NEW SPECIES AND A CATALOGUE OF STIGMODERA (CASTIARINA)
(COLEOPTERA: BUPRESTIDAE)
BY §. BARKER
Summary
A key to the sub-genera of Stigmodera Eschscholtz is given. The location of LaPorte & Gory types
of Stigmodera (Castiarina) in the Hope Department of Etymology, University of Oxford is
discussed. Seven species previously considered members of the sub-genus Castiarina are
transferred: alternata Lumholtz, maculiventris MacLeay, nickerli Obenberger, praeterita Carter,
punctatostriata Saunders and secularis Thomson to the sub-genus Themognatha; rudis Carter to
Stigmodera (sensu stricto). Replacement names are given for three primary homonyms: auripennis
Barker for aurifera Carter 1922 (a primary homonym of S. aurifera) LaPorte & Gory 1837); planata
Carter, an available synonym for auricollis Thomson 1857 (a primary homonym of S. auricollis
LaPorte & Gory 1837); magnificollis Barker for magnifica Blackburn (a primary homonym of S.
magnifica LaPorte & Gory 1837). A replacement name is given for one secondary homonym:
hoblerae Carter for mastersi MacLeay 1872, a secondary homonym of S. mastersi (MacLeay) 1872,
subsequently transferred to Stigmodera from Neocuris.

Introduction
Stigmedera Eschscholtz 1829, with more
than 400. described species, is the largest genus
within the Australian Buprestidae. In Stigmo-
dera the mouthparts are produced downwards
to form a short rostrum, the pores on the
antennae concentrated into fovea on the
toothed segments, the labrum long, coloured
like the clypetis, the posterior edge of the
Key to sub-venera of Stigmodera (modified from Carter,
|. Elytra hollowed out with large foveoles; medium to large size
pronotum sinuate, the frons not narrowed
between the antennal cavities (Britton, 1970).
There are three recognised sub-genera: Stig-
modera (sensu stricto) Eschschollz 1829, type
species macularia (Donovan) 1805, with a
total of eight species; Themognatha Solier
1833, type species variahilis (Donovan) 1805,
with over J00 species; Castiavina LaPorte &
Gory 1837, type species perty? LaPorte & Gory
1837, with aver 300 speeics,
1929)
Stixmodera (sensu stricto)
Elytra striate ar punctate-stiute: sometimes with costac 2

scutellum; medium to large size
Themognatha
Tarsal hooks always simple; never with hair on ilersal surface of head; scutellum heart-shaped or
shicld-shaped never round or oval; small lo medium size
Thery (1937) subdivided Themognatha but
here | consider it a single sub-genus. Despite
its sive the genus has never been revised in

species, a check-list and a key to the species

of jhe sub-genus Castiarina. Here I present

are completed.
LaPorte & Gory types in tie collection of the
Hope Departinent of Entomology
The pamphlet on Australian Buprestidae,
privately circulated by the Rev. F. W. Hope
in 1836 was cited by LaPorte & Gory (1837)
in their monograph, but was subsequently
declared unavailable for the purposes of
nomenclature by the International Commission
on Zoologieal Nomenclature (1948), thos
legalising a decision made 80 years previously
by leading British eniomologists of the day
(Proc. ent. Soc. Lond. 5: cix-cx, 1868), The
only objection was lodged by Dr J. Obenberger
of Prague. Later Obenberger (1955) had his
personal copy of the Hope pamphlet photo-
graphically reproduced in a paper, to muke it
‘available to all scientific investigators’.
Although the Hope pamphlet remains unavail-
able for the ptirposes of nomenclature, the
Hope “types” are extant. 1 have found that the
types of some of the LaPorte & Gory species
are not held in the collection of the Paris
Museum. The species in question were attri-
buted to Hope hy LaPorte & Gory (1837), and
under the relevant names the phrase “Du cabi-
net de M. Hope” appears in brackets, Authen-
ticated specimens of all of these species are
held in the Type collection of the Hope De-
partment of Eutomology, University of Oxford,
The LaPorte & Gory names and the Hope
Department of Entomology numbers are:
S, semricineta 982;.8. antabilis 983; 8, andersoni
959; S. erventa 970; §. bicingulara 963; 8.
bivinera 962+.8. jaypilota 967; 8. sexspilota 968,
5S. siehold| 969; 8. apicalis 965,
1 conclude that the above specimens are the
types of (he respective LaPorte & Gory species.
Species herein remaved Jrom the sub-penus

The following species are transferred 10 the
sub-eenus Theppogrtatha.

Introduction
The Burra Group in South Australia is a
major sedimentary cycle beginuing with a basal
sequence dominated by terrigenous clustics,
and may unconformably overlie basement or
older sedimentary sequences of the Callana
Beds. This dominantly clastic sequence 1 over-
lain by a mixed carbonate-clastic sequence
characterized by the presence of magnesite,
particularly in the upper part, This latter
sequence has been investigated by Howchin
(1915), Mawson (1941. 1947), Forbes (1960,
196]) and Preiss (1973). The remainder of
the Burra Group is a dominantly clastic
sequence With Variable development of dolo-
mite. Within the Adelaide Geosyneline, the
Burra Group has an extremely widespread dis-
tribution, from the southern Mt Lofly Ranges
to the Peake and Denison Ranges. 750 km
northwest of Adelaide.
The sedimentary sequence characterized by
magnesite has almost as widespread a distribu-
tion as the Burra Group itself. The Skillogalee
Dolomite was proposed by Wilson (1952) to
refer to this interval in’ the Riverton-Clare
region, and this nomenclature was followed by
Mirams & Forbes (1964), Subsequently the
term Skillogalee Dolomite has been used in
other areas in Which this sequence occurs with
the exeeption of the Adelaide region (Forbes
1971), The Castambul Dolomite and Monla-
cute Dolomite were proposed for this sequence
in the Adelaide region (Mawson & Sprigg
1950). In some areas the Skillogalee Dolomite
has been subdivided into two unnamed mem-
hers (Coats ef ul, 1969), The correlation of
sequences in other areas with the lype section
of the Skillogalee Dolomite has been based on
the presence of dark grey dolomite, and mag
hesite, However detailed work still in progress
by the author, indicates sufficient mappable
lithological differences within the interval
referred to as the Skillogulee Dolomite, to war-
rant the introduction of additional stratigraphic
nomenclature. Murrell (1977)! discusses an
unpublished nomenclature for this interval in
the Willouran Ranges, and correlation of this

Basis for revision
The sedimentary sequence deposited after
ihe Aldvate Sandstone and its equivalents, and
coding with the cessation of magnesite deposi-
tion, represents a very shallow water phase of
sedimentation, encompassing smaller scale
transzressive-regressive cycles. Sedimentation
was characterized by a specific basin chemistry,
with dolomite as the prevailing carbonate
throughout the basin, while magnesite was pre-
cipitated on the margins. However facies
changes between areas resulted because of
variable influxes of terrigenous clastics, relative
proximity to the basin margin, and tectonic
influences on basin morphology and suhsideuce
Tales
Wuhin the southern and northern Flinders
Ranges, the sedimentary interval referred to as
the Skillogalee Dolomite, contains several litho-
Sogically distinct and mappable units, although
intertonguing relationships occur, The applica-
tion of a single formation name to this interval
obscurcs the vertical und lateral relationships
between these units, and the different deposi-
teonal environments which they fepresent,
Hence a revised stratigraphic nomenclature is
propesed (Table 1), and the relationships
between the existing and proposed formations
ure discussed below. The Mundallio Subgroup,
after “Mundatlio” H.S. 10 km northeast of Port
Augusta, has been introduced because of the
oveurrence of these formations in a cycle of
regressive, shallow-water, mixed carbonate-
clastic sedimentation. The type sections of two
Fig Lt.
ot the proposed formations, are located 25 km
north of “Mundallio” HLS, in the vicinity of
Depot Creek (Fig. 2A), an area which has
been used to illustrate the important features
of this interval, to a much greater extent ‘than
the type section of the Skillogalee Dolomite in
Skillogalee Creek, The two formations defined
have excellent exposure, and one (the Yad-
lamalka Formation) is the most extensive for-
mation in the proposed Mundallio Subgroup
(Fig, 1).
Discussion and revision of existing formations
CASTAMBUL AND MoNnTACUTE DoLomrres
This nomenclature was introduced by Maw-
son & Sprigg (1950), to refer to the two major
dolomite horizons between the Aldgate Sand-
stone and the Stonyfell Quartzite if the
Adelaide region. The present Burta Group
nomenclature in this Tegiow is summarized by
Forhes in Daily et al. (1976). The Castambul
Dolomite is an essentially homogeneous,
cream coloured, recrystallized dolomite with
minor sandy and shaly intervals. The Mon-
tacute Dolomite is a more variable unit con-
sisting of dark grey, variably reerystallized
dolomites, fine-grained laminated magnesite.
intraformational dolomite and magnesite con-
glomerates, and dolomite-cemented sandstones.
Rapid vertical and lateral facies chanyes occur
within the Montacute Dolomite. Both forma-
tions are of only localized occurrence (Fig, 1),
with the most significant outcrops occurring im
the Torrens Gorge area, where they are
ussociated with siltstones aod minor sand-
stones. Elsewhere in the Adelaide regiin, this

sequence is dominated by siltstones of the
Woolshed Flat Shale (see below }.
In order to simplify the nomenclature pro-
posed by Mawson & Sprigg (1950), it is pro-
posed that the Caslambul Dolomite be
renamed the Caytanbul Formation and refer
to the interval from the top of the Aldgate
Sandstone to the hase of the Montacute Dolo-
mite in the Torrens Gorge area. Hence 1 will
include the “unnamed shites” of Mawson &
Sprigg (1950).

These formations were proposed by Wilson
(1952) in the Riverton-Clare region, He
described the Skillogalee Dolomite as “cream
colourcd fine- to medium-grained dense dolo-
mites with occasional interbedded dolanvitic
shales. . in several areas notable bluc-grey
members appear in the uppermost sections of
the formation” (Wilson 1952), The eream
coloured dolomites, which comprise most of
the formation, are extensively recrystallized,
obliterating the original sedimentary textures
and structures. Apart trom a few poorly pre-
served stromutolites. clues to the nature of
the original sediment are rare, The lenticular
dark grey dolomites are less recrystallized, and
origiated as laminated mudstones (in the
sense of Dunham, 1962) with minor strommte-
lilic horizons, Rare intraformational magnesite
cunglomerite is present. The outerops in Skil-
laogalee Creck extend northward to Spalding,
and a similar sequence occurs south of Burra
The term Skillogalce Dolonte should refer to
outcrops in these dreas only, That is, where the
dominant facies as eream coloured, reerystal-
lived dolomite, Other outerops which have
previously been referred to as the Skillowalec
Dolomite will be incorporated in the new for.
mations proposed helow
In its type section, the Skillogalee Dolomite
is overlain by laminated grey siltstoues uni
Shales of the Woolshed Flat Shale. Laterally, it
passes jato the Woolshed Flat Shale to the
southeast.

The Nathaltee Formation, after Nathaltec

taining light erey or creamy dolomite beds’
mapped by Binks (1971) io the southern Flin-
ders. Ranges as the lower part of the Skillogalee
Dolomite. The Depet Creek area (30 km
northeast of Port Augusta), deseribed by
Preiss (1973), has been selected as the type
area for the Nathaltee Formatiow. The type
section is located 1 km south of Depot Creek
(Fig. 24) and was preferred to that in Depot
Creek because of the influence of minor dia-
pirie breccia in the latter section. The transi-
tional contact with the rnderlying Emeroo
Quarizite is marked by the introduction of
dolomites and siltstones jnto the sandstone
dominated sequence al the lop of the Emetoo
Quurtzic, Interbedded sandstones continue
intr the lower part of the Nathaltee Formation,
which is divisible into three informal snits
totalling 135 m thick (Pig. 3).

coloured lithologies, allhough the lower few
meires are characterised by vross-cutting red
ortdation Zones, PM consists of about two-thirds
curbonate facies and one-third lerrigenous clas-
tics, The carbonate facics are duminated by
grey and dark-grey laminated dolomicrites with
pale-grey to black chert nodules. The dolomite
has reerystallized to microspar, bur the sedi-
ments clearly originated as mudstones fin the

conulomerate. Stromatolites, which occur as
hoth columnar and domal forms, are similar
petrologicilly to the latmnated dolomicrites,
und also contam irregular black chert nodules,
Intraformational magnesite conglomerates are

NANKANUNYANA FORMATION
The Nankabunyana Formation, after Nanka-
bunyana Well, 16 kin west of Copley, applies
to the mixed clastic-dolomite sequence between
the Copley Quartzite and the dolomite-mag-
nesite-sandstone sequence of the Yadlamalka
Formation (see below) in the northern Flin-
ders Ranges, This sequence has previously
been referred to as the lower unnamed oiem-
ber of the Skillogalee Dolornite (Coats ef al.
1969). The Nankabunyana Formation is
sequence of interbedded sandstones and sill-
stones, with minor dolomite interbeds {see
helow), whereas the Nathallee Formation.
which occurs in the southern Flinders Ranges,
consists of interbedded siltstones and dolo-
mites, with minor satidstone interbeds, that
were deposited in a lower energy regime. (com-
parc Fres 3 and 4), In the type section, 6 km
southwest of Copley (Fig, 2B), the Nanka-
hunya Formation is 538 m thick, but thickens
northwestward fo 715 m at Myrtle Springs,
The Formation may be subdivided inte four
informal imits (Fig, 4).

yaha Formation occurs at the lop of the last

boundaries are sharp, indicating little inter-
mixing of the finer and coarser components of
the sequence. However occasional fining up-
ward cycles oceur, and consist of cross-
laminated sandstone overlain by interlaminated
sandstane and siltstone capped by laminated
siltstane (Fig, 10). The only significant dolo-

refers to that part of the previously mapped
Skillogalee Dolomite characterized by inter-
bedded dark grey dolomite, intraformational
magnesite conglomerate and dolomitic sand-
stone, “The 258 m thick type section (Figs 2A

scale slumping and disruption occurred while
the sediment was still in a plastic state. Desic-
cation cracks are relatively common, but tepees
are small and rare, indicating that only thin
lithified crusts formed during periods of
exposure. Secondary silicification prior to and
during lithification and compaction, produced
lenses and nodules of black chert.
Stromatolites occur in biostromes and bio-
herms of dark grey dolomicrite, and both
columnar and domal forms are present (Fig.
12), The latter may grade into irregularly
laminated dolomicrites, representing a grada-
tion from an algal controlled fabric to planar
laminated dolomicrites in which the shape of
the lamination is not organically controlled.
Stromatolites are most abundant in the middle
of the formation where the sand content is low.
Grain supported dolomites are minor, and
include sandy intraformational dolomite con-
glomerates, oolitic dolomites and oncolitic
dolomites. Oncolites are frequently silicified,
and textures of unsilicified oncolites are poorly
preserved because of a high proportion of
organic matter relative to dolomite in the
oncolites, prior to diagenesis. Individual onco-
lites are either concentrically laminated with
asymmetric growth (up to 2 mm in size), or
internally massive (up to 1 cm in size). Onco-
litic dolomites occur as lenticular beds within
dolomicrites, or in more massive beds up to 0.5
m thick which may be associated with stro-
matolites.
Magnesite, comprising about 11% of the
type section, occurs most commonly as intra-
formational conglomerates, and only rarely as
laminated micritic magnesite. Intraformational
conglomerates are most abundant in the
sandier lowermost and uppermost parts of the
formation, and may contain a high proportion
of sandy dolomitic matrix, and a maximum
intraclast size of several centimetres. Elsewhere
intraclasts are frequently close packed with
little matrix. Those beds with a higher propor-
tion of matrix are more poorly sorted and may
be inverse graded (Fig. 13). This feature may
be caused by a high concentration of clasts and
matrix in the transporting medium during high
energy periods. As a result larger intraclasts
move to regions of least shear away from the
bed, while smaller intraclasts remain near the
sediment interface. Very rapid deposition may
preserve this clast size distribution resulting in
inversely graded beds (Davies & Walker
1974). Inversely graded beds almost certainly
represent a single depositional event such as

that resulting from a major storm. Ripple
marks and cross bedding occur rarely in finer
intraformational conglomerates, and indicate
reworking of intraclasts by waves and currents.
Laminated micritic magnesite and individual
intraclasts of magnesite have a very low con-
tent of silt and sand size terrigenous sediment,
and their micritic texture indicates that very
early diagenentic lithifization has inhibited re-
crystallization.
Interbedded sandstones are most common
near the base and top of the formation.
Average grain size is fine- to medium-grained
sand, and dolomite cement is ubiquitous. How-
ever sorting is only moderate, due to the wide
range of grain sizes present in individual beds
(coarse-grained silt to coarse-grained sand).
Petrologically the sandstones are subarkoses,
with potassium feldspars more abundant than
plagioclase, Sedimentary structures include
tabular crossbeds indicating easterly flowing
currents, symmetrical wave ripple marks, and
desiccation polygons up to 15 cm in size, Silt-
stones and shales are of minor importance
(Fig. 5).
Distribution of the Yadlamalka Formation
The distribution of this formation is shown
in Figs 1 and 7. In all areas of occurrence the
formation is characterized by facies similar to
those described above for the type section.
Thicknesses are variable and reach a maximum
of 3000 m in the area southwest of Rischbieth
Hut in the Willouran Ranges.
In the southern Flinders Ranges between
Port Germein Gorge and Yacka very sandy
sequences with only minor magnesite occur
(Forbes 1960). East of Yacka, on the River
Broughton, approximately 57% of the Yadla-
malka Formation is dolomitic sandstone, and
10 km to the west carbonate deposition was
outweighed by clastic deposition, to such an
extent that the Yadlamalka Formation cannot
be distinguished from the underlying Bungaree
Quartzite and overlying Undalya Quartzite
(Fig. 7A). Hence there was a relatively con-
tinuous influx of sand into this area during
deposition of the Yadlamalka Formation.
However in the Depot Creck area, this influx
was significant only near the base and top of
the formation, In the more easterly sections in
the centre of the ORROROO 1:250 000 map
sheet, the sandstone content is generally low,
and dark grey dolomicrite is the dominant
lithology. The percentage of magnesite is low
in the southern Flinders Ranges, apart from

dominantly as intraformational conglomerates,
The maximum ovceurrence is southwest of
Copley (Forbes 1960) where 18% of the for
mation is intraformational magnesite conglo-
merate, and 3% is laminated micriic maz-
neste. This may be attributed to very low
deposifional slopes resulling m broad areas of
Magnesite deposition on the basin margin.
These areas were sithjected to extensive pene-
contemporaneous erosion. A 60% inctease in
thickness of the Yadlamalka Formation occurs
between Copley and Myrtle Springs, with vir-
tually no facies changes, Hence depositional
rates matehed differential subsidence because
of favourable conditions for carbonate deposi-
tion. A shallow Water environment with vir-
tually no deposilional slope was maintained,
Dark-grey dolomicrites, and grey very fine-
grained sandstones, are the other major litholo-
gies in the Copley area and, along with mag-
nese, alsa dominate outcrops of the Yadla-
malka Formation in the Arkaroola region In
the southwestern Willouran Ranges, the inter-
yal equivalent te the Yadlamalka Formution,
has been designated the “Cadnawitana Forma-
won” by Murrell (197714. However hecause
similar facies are present in this region, in the
remainder of the northern Flinders Ranges,
unct in the type section of the Vadlamalka For-
mation, this formation may also he used in the
southwestern Willouran Ranges. However in
this area the clastic content increases, and the
magnesite content decreases, in @ northeasterly
direction, and the Yadlamalka Formation is re.
placed laterally by the “Mirra Formation’’
(Murrell 1977'), This formation is charac-
terized by more than 50% torrigenous sedi-

The most abundant carbonate facies is dark

Micritic magnesite formed in low energy en-
vironments on marginal shelves and restricted
lagoons. The absence of stromatolites indicates
that these environments were unfavourable for
persistent organic activity. The magnesite was
subjected to extended periods of exposure dur-
ing which tepees and lithified crusts formed.
Erosion of these crusts resulted in deposition
of intraformational magnesite conglomerates
in a range of environments from marginal mag-
nesite lagoons to subtidal dolomite environ-
ments, Low depositional slopes produced sheet
conglomerates rather than channel based beds,
The presence of dolomite as a matrix m intra-
formational magnesite conglomerates, and the
rare occurrence of interlaminated dolomite and
magnesite, indicate that these two minerals
formed from different precursors and virtually
penecontemporuncously with deposition.

dominant process in depositinae these sand-
stones (Reineck & Singh 1973).
Much of the above discussion is also
applicable to the Montacute Dolomite which
contains similar facies to (he Yadlamalka For-
mation. However the Montacute Dolomite is a
much more localized formation and contains
thure rapid lateral facies changes than they Yad-
lammalka Formation.
Brief regional synthesis
The distribution and relationships between
the formations of the Mundallio Sabgrowp are
indicated in Figs |, 6 and 7. The farmattons
which are proposed are lithostratigraphic units,
and their boundaries are likely 19 he time trans-
eressive, The boundaries of the Mundallio Sub-
group are generally well defined, especially on
the western margin of the Mi Lofty and
southern Flinders Ranges, where the subgroup
eecurs between two distinctive sandstone
dominated sequences, Well defined boundaries
alse Geeur in the northern Flinders Ranges,
and itt most of the Willouran Ranges, where
ihe Mundalllio Subgroup is underlain by
quartvitus, and overlain by a siltstone-sand-
stone sequence (Myrile Springs Formation).
However lithological similarities between dolo-
mite interheds within the Bufiyaree and Yed-
nalue Quartaites, dolomite interbeds within the
Nathaltec Pormation, and the Skillogalee
Dolomite, indicute that the possibility of inter
longing between the Mundallio Subgroup and
the tnderfying, quartzites cannut be excluded
The shallow to very shallow water sediments
of the subgroup overlie sandstones of the lower
Burra Group. These sandstones were probably
more widely distributed than the more reures-
sive Mundallio Subgroup and may have pro-
Vided a source for sandstones deposited within
the Mundalho Subgroup. The lower part of the
subgroup contains a wide spectrum of facies.
This resulted from variable subsidence and
depositional rates allowing the development of
suh-basins, with Variable water depths and
depositional slupes across the basin as a whole
Significant deposition of teerigenous detritys
occuned in many areas, andl exceeded dolo-
mite deposition. As a result the Nathaltee For-
mation und ihe Nankabunyana Formation
were deposited in those areas with an open
circulation system which supplied detrital sedi-
ment, However in other areas Which were more
protected from the influx of terrigenous seui-
ment and had favourable water chemistry for
carbonate deposition, dolomite deposition
exceeded that of terrigenous clastics and
deposition of the Yadlamalka Formation com-
menced, This probably occurred in the Mun-
dallio Creek area and m the vicinity of Yed-
nalue. Qutcrops of the Skillogulee Dolomite
also have # Jow content of terrigenous
matcrial, and Were protected from the influx of
detritus hy deposition on a broad shallow low
energy platiorm, A shallow topographic high
extending southwards ffom Spalding may have
provided a physical barrier to detrital influx,
and thus explain the rapid facies charges with-
in the Mundallio Subgroup helween Yacka and
Spalding (Fig, 7A).
Higher in the subgroup, deposition of the
Yadlamalka Formation occurred in a shallow
basin with similar water depths over large
areas. and low depasitional slopes. Ag a result
sinvlar facies were deposited throughout much
of the Adelaide Geosyncline. Dolomite heewme

Summary
Kanmantoo Group metasediments cropping out between West Bay and Breakneck River, Kangaroo
Island, South Australia, exhibit three phases of deformation. Each phase has developed macroscopic
and mesoscopic structures, as well as an axial plane schistosity. The development of these
schisosities in one area is unusual for the Kanmantoo Group.

Kanmantoo Group metasediments cropping out between West Bay and Breakneck River,
Kangaroo Island, South Australia, exhibit three phases of deformation. Fach phase has
developed macroscopic and mesoscopic structures, as well ws an axial plane schistosity, The
development of three schistosilies in one urea is unusval for the Kanmuntoo Group,
The first folding phasé (D,) produced regional east-west upright horizontal folds with axial
plane schistosity, quartz veins and parallel differentiation layering, The second folding phase
(Ds) developed abundant mesoscopic upright plunging folds with axial plane fabric elements
of schistosity, crenulation cleavage and reoriented transposed bedding, Third phase mesoscopic
and macroscopic folding (Dy) has axial plane fabric elements of crenulation cleavage, differen-
tiation layering, schistosity and transposed bedding.
Metamorphism was at a maximum (andulusite-staurolite zone, amphibolite facies) during
D, folding, and §; fabrics are characterised by a high degree of textural equilibrium, Alumina-
rich and granitic pegmatites were intruded during D, folding. From post-D, to syn-Dg, biotite
zone (greenschist facies) conditions prevailed but with af increase in textural disequilibrium
towards Dy, Retrogression during chlorite zone (greenschist facies) conditions occurred after

Introduction
Metasediments cropping out between West
Bay and Breakneck River in Flinders Chase
National Park, Kangaroo [sland, South Aus-
tralia (Flint |978, big. 1) were examined to
determine their sedimentary, petrographic and
structural history, The metasediments are
ussigned to the Kanmantoo Group of Cam-
brian age (Thomson 1975, Daily & Milnes
1971) by lithological correlation with Kane
mantoo Group metasediments in their type sec-
tion. Metamorphism of the Kunmantoo Group
in its type section is Jower Ordovician (Dasch
et al. 1971; Milnes et al. 1977). Sedimento-
logical aspects and stratigraphic correlations
are discussed in Flint (1978), in which the
stratigraphic sequence of the West Bay area
has been correlated with the Inman Hill Por-
mation of Thomson (1969) and the Tapa-
nappa Formation of Daily & Milnes (1972).
This report outlines details of a mesoscopic
geometric structural analysis and microscopic
textural analysis of the metasediments, exposed
in a thin strip of coastline, 20 m wide and §
km long (Fig. 1),
Rock types exposed are predominantly
quartz-rich metasandstones and quartz-mica
schists, Rarer types are metalutites, metasand-
stones rich in heavy minerals, and granitic and
alumina-rich pegmatites. Bedding surfaces
(S,,) ure always recognisable throughout the
map area, Rock types and sedimentary struc-
tures are involved in cyclic sedimentation
units, and are discussed in Flint (1978).
The Kanmantoo Group metasediments
exposed in the study area record three defor-
mation or folding phases. Similar results have
been obtained from other areas within the Mt
Lofty Ranges for Kanmantoo Group and
underlying Adelaidean metusediments (Offler

phases of folding are recognised in the type
section of the Kanmantoo Group between
Cape Jervis and Victor Harbor (Daily &
Milnes 1971, 1973).
The structural analysis here is based upon
abundant and widespread mesoscopic over-
printing criteria and the assumption of
coherence of orientation of tectonic fabric
elements. Different phases can have similar
fold styles and axial plane structures. The type
of structure developed is a function of:
I. type of sedimentological sequence (sequence
| and 2 of Flint 1978),

2, position (and henee rock Type) within dhe
cyche sedimeritation Units,
3. intensity of deformation,
Within a single cycle sedimentation unit of
either sequence 1 or sequenee 2 type, the
type of structure for a particular phase changes
with changing lithology. The abundance of
structures and the apparent intensity of defor-
mation is strongly dependent upon the type of
sedimentological sequences. The different types
of cyclic sedimentation units ure spatially
separated (Flint 1978, Fig, 2) and this pro-
Vides it basis for subdivision of the urea into
two structural domains (Fig. 1), Tectonic
structures are poorly developed in the northern

Although mesoscopic D, folds are lacking,
observations and interpretations from the map

folding generally produced the major regional

lulite sequence north of West Bay (Flint 1978,
Fiz. 2), while they are almost absent in the
sequence 2 metasandstones. The third phrase
plinur fabric clements are schistosity, trans-
posed tedding and strongly deformed sedi-
mentury structures: The S,, schistosity, where
present, is defined by a well-developed
preferred orientation of muscovite and biotite
(Figs 8-9). Transposition of bedding and
strong flattening of sedimentary structures
along Sy surfaces are common responses to Dy
withia the metalutiles (Pig. 10). Complete
transposition of bedding in some instances has
prad\iced a fabric which has the wppearance
of an imbricated intraclastic conglomerate but
with & planar fabric clement parallel to S,
planes jn adjacent rocks. These Sy planes have
the same orientation aa §. erenulations in sub-
area 2 Macroscopic folding of earlier struc-
tures during Dy is not evident.
In sub-area 2, the most common S, struc-
tures are crenulation cleavage and differentia-
tion layering, Which are axial plane to foldest

The area mapped has heen divided inta two

mentological boundaries, abundance of meso-
scopic tectonic folds in bedding, and regionally
significant change in S,, orientation,

sequence 2 deposits with metasandstones the

Small lenticular units of more calcareous com-
position often exhibit a mortar-like texture.
Extensive nucleation and limited grain growth
along grain boundaries has produced the
apparent cataclastic texture.
Microscopic textural analysis
The crystallisation-deformation relationships
have been determined microscopically, using
the technique of Spry (1969) to establish
changes in grade of metamorphism during the
deformation history. Thin sections which form
the basis of these observations and interpreta-
tions are deposited at the Flinders University
of South Australia (numbered 2-7-4 to
2-7-57). Terminology of metamorphic zones
(chlorite, biotite and andalusite-staurolite) fol-
lows that of Offler & Fleming (1968).
Mineral Growth Synchronous with First-
Generation Structures
S, schistosity, where developed, is defined
by a perfect (001) mica cleavage and dimen-
sional preferred orientation of biotite and mus-
covite, Textural equilibrium is indicated and
chlorite is absent in S, schists and structures.
Staurolite is developed on the margins of some
$8; quartz veins within sub-area 1. Staurolite
poikiloblasts exhibit sigmoidal trains of inclu-
sions with the internal fabric often continuous
with the external fabric (S,), and the 8, schis-
tosity tends to wrap around the porphyroblasts
indicating pre-to syntectonic growth. Stauro-
lite in the absence of chlorite, and textural
equilibrium indicate staurolite zone (amphibo-
lite facies) conditions during the D, folding,

during the D, folding. Quartz-leldspar pexnr-
Hites (containing tourmaline and garnet) are
folded disharmonically by Du and contain J.

As andalsitestauralite zone conditions are
postulated to have been attained only during

West Bay area were intruded during the first

Discussion
Deformation involving an axial plane schis-
tosity with cach of the three significant folding
phases in such a small area is unusual, Folding
phases D,-D,—D, of OMer & Floming (19683)
und 194-D, of Daily & Milnes (1973) are
correlated with the three deformations in Flin-
ders Chase.
D, tolding has caused the regional trends in
hedding orientation, an |literpretation common
to many studies on the Kianmantoo Group.
Minor macroscopic warping with crenulation
cleavage and rare schistosity development
usually typifies D. and Dy (OMer & Fleming
1968). In Flinders Chase both Du and Dy
macroscopically and mesoseopically fold
earlier structures with the development of
crenulation cleavages and schislosities. Mow-
ever, Offler & Fleming (1968) report that Dy
axial surfaces are usually steep and have a
meridional trend, but hear West Bay S_ has an
average orientation dipping 45° towards 035".
Subdivision of metamorphic grade jnte
chlorite, biotite: and andalusite-staurolite zones
(Offer & Fleming 1968), is consistent with
observed assemblages in Flinders Chase.
Mineralogy and apparent petrogenesis is in
keeping with low-pressure intermediate facies
seTics metamorphism; a vonclusion of Joplin
(1968), Olller & Fleming (1968) and Daily &
Milnes (1973),
In Flinders Chase, the only amphibolite
facies index mineral observed is carly- to syn-
Dy staurolite. Pre- to carly syn-D, cordierite
and quartz azeregates have heen identified at
Viclor Harbor (Daily & Milnes 1973), Else-
where, post-D,, amphibolite facics mineralogy
is commonly observed within the D,-D., inter-
Kinematic period representing the mujer
development of porphyroblasts (Offer &
Fleming |968). Post-D, and pre-B. porphy-
Toblasts are completely lacking at West Bay. Io
general, Offler & Fleming (1968) regard syn-
tectonic porphyrablustic growth as rate but in
Flinders Chase, Dy is associated with porphy-
foblastic staurolite and maximum grade of
metamorphism.

Introduction
Despite increasing interest in Australia’s
inland water resources, little is Known of the
ubiquitous rotifer fauna. Since the work of
Anderson & Shephard (1892), Colledge
(1909-1924), Shephard (1892-1922) and
others, the only reports of Rotifera have been
species lists from single collections (Russell
1957, 1961; Berzins 1953, 1955, 1963) or
individual descriptions (Sudzuki 1975; Sud-
yuki & Timms 1977), Taxonomic confusion
within the group has persisted; no adequate
record of the rotifers of Australia is extant.
This paper contributes a list of all species
recorded to date from the continent. Recent
advances in taxonomy, particularly with the
recognition of morphological variability within
species (see Koste 1978) has enabled synony-
mies to be established for many of the early
records. Of more than 450 recorded species,
279 are recognized here. A further 52 taxa are
recorded for the first time as a result of a sur-
vey of the zooplankton of the Murray-Darling
system (Shicl 1978, 1979, in press, in prep.!:
Koste 1979). Varieties are included in the list
because in some cases they are the only repre-
sentatives of the species found to date in Aus-
tralia.
The format adopted is as follows: valid
species names sare given in alphabetical order,
Frequently occurring synonyms and date of
synonymy are given with each valid mame, as
are locality data and principal references.
References citing Rotifera to genus only have
been excluded, as have some of the many early
works with repetitive listings. Nomina dubia
and records which are uncertain due to insuf-
ficient information, typographical or locality
errors are listed separately. Sources of
synonymy are: Chengalath (1977), Harring
(1913). Koste (1978), Kutikova (1970), Rus-
sell (1961), Ruttner-Kolisko (1974), Sudzuki
(1964) and Voigt (1956/1957).

HOLOCENE STRATIGRAPHY AND EVOLUTION OF THE COOKE
PLAINS EMBAYMENT, A FORMER EXTENSION OF LAKE
ALEXANDRINA, SOUTH AUSTRALIA
BY C. C. VON DER BORCH AND M. ALTMANN
Summary
The Cook Plains Embayment occupies an emergent area that was recently innundated by Lake
Alexandrina. The embayment is underlain by a Holocene sedimentary succession several metres
thick, the stratigraphy of which reflects some aspects of the late Holocene climatic and other
changes in the vicinity of the River Murray delta system. The most likely cause of the late Holocene
expansion of the lake system is considered to have been increased inflow to the lake from the River
Murray, during the world-wide “pluvial” period that occurred 5000-8000 years ago. A contributing
cause may also have been the peak of the Holocene marine transgression which is dated in southern
Australia at around 6000 years ago. The slightly higher than present sealevel stand may have
backed up lake waters by raising baselevel, with a consequent rise in groundwater table. Some
direct inflow of ocean water may have also taken place at this time. Subsequent to the high lake
stand, increased aridity combined with a slight sealevel fall lowered lake level approximately to its
present situation. The paleaoclimatic events deduced from the stratigraphy of the Cooke Plains
Embayment are consistent with those proposed by other workers from stratigraphic evidence in
lakes of western Victoria.

The Cooke Plains Embayment occupies an emergent area that was recently inubdated by
Lake Alexandrina. The embayment is underlain by a Holocene sedimentary succession
several metres thick, the stratigraphy of which reflects some aspects of the late Holocene
climatic and other changes in the vicinity of the River Murray delta system, The most likely
cause of the Iate Holocene expansion of the Jake system is considered to have been, increased
inflow to the lake from the River Murray, during the world-wide “pluvial” period that occurred
5000-8000 years ago, A contributing cause may also have been the peak of the Holocene
marine transgression which is dated in southern Australia at around 6000 years ago. The
slightly higher than present sealevel stand may have backed up lake waters by raising baselevel,
with a consequent rise in groundwater tuble. Some direct inflow of ocean water may hive
algo taken place at this time. Subsequent to the high lake stand, increased aridity combined
with a slight sealevel fall lowered lake level approximately to its present situation. The paleao-
climatic events deduced from the stratigraphy of the Cooke Plains Embayment are consistent
with those proposed by other workers from stratigraphic evidence in lakes of western Victoria
Introduction
The River Murray forms a major part of
Australia’s largest drainage system. Its sediment
load at present is being deposited in a marine-
dominated delta comprising lakes Alexandrina
and Albert, the north lagoon of the Coorong,
and the adjacent continental shelf. In the recent
past, fluvial as well as lacustrine and estuarine
sediments were deposited over a much more
extensive area during a period when waicr level
was somewhat higher than at present, The
region involved is illustrated in part in Figure
1 and includes the present lakes and lagoon, as
well as marginal and now essentially subacrial
areas shown by the diagonally striped symbol
The youngest sediments from beneath the
lakes and exposed former extensions of the
lakes preserve a record of the Holocene history
of the River Murray delta. The contrasting
stratigraphic units reflect notable climate and
senlevel changes that have typified the past few
thousand years,
The object of this paper is. to present pre-
liminary interpretations of the Holocene sedi-
mentary units of one of the exposed, relatively
accessible portions of the delta complex, the
Cooke Plains Embayment (Figs 1-2).
Previous work
Soil surveys by Taylor & Poole (1931),
Wells (1955) and de Mooy (1959a, 1959b)
provide some imitial data in the study area.
De Mooy (1959a) specifically documented
some of the sediments on the stranded lake
flats, informally designating the characteristi-
cally dark-coloured upper sediments in areas
such as the Cooke Plains Embayment as the

seribed the widespread siliceous and calcareous
eolian sand accumulations which form the
morphological framework of the region sur-
vounding the lakes.

somewhat more elevated dunes. Two cheniers
of siliceous sand (Fig. 2) occur at the western
end of the embayment adjacent to present-day
Lake Alexandrina and these have been des-
cribed by de Mooy (1959a). Two gypsum
lunettes (Campbell 1968), occur adjacent to
the inland (eastern) end of the embayment,
one of which lies within the boundary of Fig.
2
Sand dunes, mainly of Pleistocene emplace-
ment, border the embayment. These comprise
unconsolidated siliceous sands ai the surface,
generally overlying a Pleistocene calecrete
developed on calcareous dunes. The calcrete
is onlapped by Holocene sediments of the
embayment, Some of these dunes may repre-
sent Pleinstocene marine strandline deposits
formed during interglacial high sealevel stands
(Sprigg 1952, 1959). Others are related to
sand-dritts of the arid phase which coincided
with the last glacial maximum.
The surface of the Cooke Plains Embayment
is notably Hat. It is largely vegetated by halo-
phytes such as Salicornia australis and, as such,
contrasts with the surrounding undulating topo-
graphy of the dune systems. The embayment
surface is covered in marginal areas by a wide-
spread black soil.

The former shoreline of the Cooke Plains
Embayment is defined by the slope-break
between the hulophytevegetated Hats and the
surrounding dune system, In places, particu-
larly along the northern shorelines, low (1-2
m) stranded cliffs can be observed cut into
ihe calcrete surface, marking an erosional
shoreline produced by wave attack under the
influence of high-impact south to south-west
winds, These cliffs are shown by dumpy-level
traverses to have formed when water level In
the lake was as much as 2,7 m above present
mean scalevel,
Immediately inland from these former shore-
lines, particularly along the northern margin.
there is evidence of prolonged occupation by
aboriginal Australians. Numerous circular
hearths comprising blackened calcrete cobbles
associated with black soil and charcoal frag-
ments are visible in areas where deflation has
removed an unconsolidated brown siliceous
sand from the irregular calerete sufface, Stone
artifacts are scattered over these deflated areas
atd one dune drift has heen eroded to expose
a burial site. These remains are all obviously
younger than the calerete surface, The hearths
predate the overlying brown siliceous sand
which ts of unknown age. Much of the oceupa-
tion was probably related to ihe widespread
humid climatic phase between about S000 and
5000 years ago (Bowler 1971) which resulted
in expanded lakes in many parts of the world,
However the hearths, at least superficialty,
appear more ancient and could possibly be of
Pleistocene age.
Present-day lakes Alexandrina and Albert
have been modified by the addijion of a system
of barrages. These were completed in 1940 and
now effectively isolate the lakes from scawaler
access. Prior to barrage construction a saline
tw brackish water environment existed in the
urea, Which would then have been an estuary.
Due to the barrages, the area is now lacustrine
in character and filled with fresh water, In the
ensuing discussion it will became apparent that
it is pot possible accurately to define from
existing stratigraphic evidence whether the area
was lacustrine or estuarine in character at any
one time in the pust. Accordingly In this. paper
the word lake will be used throughout, irres-
pective of whether or not a marine connection
existed,

sion. Core sites were plotted on a base map
(Fig. 2) using aerial photographs. Sites were
subsequently levelled to Australian Height
Datum benchmarks for the cross-sections
shown in Fig. 3.
Smear slides for microscopic study and
samples for X-ray diffraction and chemical
analysis were taken from split sediment cores.
Organic carbon content was determined using
the technique of Gaudette et al, (1974).
Stratigraphy
Descriptions of stratigraphic units are
presented below, beginning with the basal
Holocene unit which unconformably overlies
a Pleistocene calcrete soil. The units are shown
in the cross-section of Fig. 3.
Basal sand and clay unit
This unit, up to 60 cm thick, comprises
unconsolidated greenish clay, sand, or sandy
clay, with less typical colour variations being
dark grey or white. The contact with the under-
lying indurated calcrete is sharp. Dominant
mineralogy of the coarse fraction is quartz,
with lesser amounts of feldspar, halite and
gypsum and traces of pyrite. The fine fraction
is mainly illite and kaolinite. The unit lacks
any notable fossil biota. Diatom frustules were
found in only one sample.
The basal sand and clay unit is the most
consistent and ubiquitous of any encountered
in the Holocene section. It is found above both
low and high areas of basement calcrete
throughout most of the Cooke Plains Embay-
ment (Fig. 3). It appears to be a typical dia-
chronous transgressive sand, reworked from a
regolith during expansion of ancestral Lake
Alexandrina.
Sapropel unit
Stratigraphically above the basal unit in
central areas of the basins lies a greenish-black,
rubbery sapropel unit with a typical cheese-like
fracture. It ranges to 40 cm thick. Contact with
the underlying unit is gradational over about
one centimetre. This sapropel is dominated by
degraded remains of blue-green algae, Minor
quartz, feldspar and clay are present, along
with traces of gypsum, halite and calcite, Dia-
tom frustules occur in significant numbers
throughout. Palynological observations (W. K.
Harris, pers. comm.) reveal a dominantly
terrestrial assemblage of fossil pollen, Pollen
and cuticle fragments of Chenopodiaceae
(blue-bush and salt-bush group), Myrtaceae
(titree family), and Casuarina, dominate the
assemblage. In addition, significant amounts of
unicellular algae (Botryococcus braunii) and
Myriophyllum and Haloragis pollen are
present, The latter two species represent
aquatic plants characteristic of essentially fresh-
water swamps.
The sapropel unit is limited in its distribution
to what clearly were deepest areas of the
former embayment (Figure 3), demonstated
by its restriction to central portions of the
basins shown in Fig. 2. Radiocarbon dating of
one sample of the sapropel shows an age of
6930 + 150 radiocarbon years (GaK 6718).
Diatomite unit
A grey diatom-rich sediment, containing up
to 70% diatom frustules, overlies the sapropel.
This diatomite unit is characterized by fine
internal laminations averaging one mm in
thickness which are visible by X-radiography.
Contact between the diatomite and sapropel
units is generally gradational over several centi-
metres, Overall appearance and consistency of
the diatomite is that of a soft, very sticky clay.
Apart from diatoms, the fine fraction contains
kaolinite and illite whilst the coarse fraction
consists of quartz, feldspar, halite and gypsum.
Diatom frustules composed of opaline silica
dominate the fossil biota, Their significance as
palaeo-environmental indicators will be dis-
cussed in a later section.
In terms of its distribution. the diatomite
unit of the Cooke Plains Embayment is best
developed in the upper reaches of the Central
Basin remote from the present lake, as well as
in the Upper Basin (Figs 2-3). Stratigraphically
equivalent although less diatomaceous sedi-
ments occur in western portions of the Embay-
ment nearer the lake. Like the sapropel, the
diatomite unit generally is restricted to what
were once deeper portions of the former exten-
sion of Lake Alexandrina, generally in centres
of the basins. However it is more widespread
than the sapropel, occasionally occurring
directly above the basal sand and clay unit
beyond the lateral extent of the sapropel (Fig.
3). This relationship suggests that the estuary
or lake was still expanding during diatomite
deposition.
Yellow clay unit
This unit, basically an unconsolidated yellow
clay up to 1 m thick, overlies the diatomite
with a gradational contact. Where the diatomite
74 Cc. C. VON DER BORCH & M, ALTMANN
is absent it overlies cither the sapropel or the
basal sand and clay unit. Typically it exhibits
bright yellows, browns and rust-reds of oxidised
iron, The clay-sized component of thrs wnil,
Which is dominant, consists of illite alang with
up to LO% CaCOy. The coarse fraction com-
prises (eypsum, halite and sand-sized quarte,
Diatom frustules. the only obvious biotic
remains, ace sporadic in their distrihution,
The yellow clay unit js areally more wide-
spread than all undestying units with the excep-
tion of the basal sand and clay (Fig, 3), sug-
gesting formation during the maximum Holo-
cene extent of the lake. It is particularly well
developed in the Upper Basin, Its oxidized
appearance and marked local colour Varia-
bility 1s most likely due to ils stratigraphic level
which lies above present-day summer ground-
water table, During its deposition it may have
contained significant sulphides, subsequent
vadose oxidation of which may have produced
the observed iron-staining An equally Feasible
explanation of the staining wauld be that it
was due to oxidation of iron sulphides carried
upwards by proundwaters from underlying sui-
phide-rich sediments,
Arkosle sand unit
A testurally mature arkosic sand unit up to
40 cm in thickness oceurs stratigraphically
ahove or interfingers with the yellow clay unit.
Contact With the clay is gradational. Like the
Yellow Clay Unit it is pigmented by ferric
von, Shells of the small gastropod Cexfella
confisa frequently occur near the lop of the
arkosic sand unit, indicative of progressive
develupment of 4 shallow, ephemeral jake
environment during the overall shoaling phase
Rare diatoms are also preseor at this level,
The arkosic sand unit was not detected in
the Upper Basin or it partions of the Central
Bosin remote from present day Lake Alexan-
dina. However, it constitutes a large portion
of the cores frora the Lower Busins and
western Ceolral Basin, where it shows the
previously mentioned interfingering relationship
with the yellow clay unit, Tt therefore is con-
sidered (4 be in part time-equivalent to the
yellow clay unit, and with jt representative of
the maximum stand of the Jake. It appears
genetically related to twa now dry channels
(Hlind Creek, and an un-named one to the
north, Pig, 2) which connect the Lower to the
Central Basins. This possible velationship is
supported by the Fact that the arkeasie saud
init seems most prominent near the inner
terminations of these channels in the Central
Basin, The sand has a wedge-shaped geometry
which progressively thins to the cast, implying
a Westerly origin in the form of a tidal delta
or washover fan ftom the direction of present.
day Lake Alexandrina. Progressively shoaling
conditions indicated by the unit are likely due

water level, Whatever the cause, the tap of the
unit marks the end of the transgressive phase
as recorded in the sediments.
Carbonate weit
A carbonate unit Up to 90 em thick. typically
a white clay-like sediment, overlies the arkosic
sand or yellow clay in some areas. Its contact
with underlying nits is gradational over
several centimetres. Fine-grained magnesian
caleite is the sole carbonate mineral present.
Gypsum and halite, along with minor quartz
and illite, are detected on hulk X-ray diffracto-
Meter determinations. The proportion of calcite
ranges between 10% and 60%, Shells ot
Coxiella con/usa ave common throughout the
calbonate unit. This species lives in great pro-
fusion in shallow (20-30 cm) ephemeral
carbonate lakes of the Lower Basins, and in
similar ephemeral alkaline lakes throughout
the Coorong region (von der Borch 1965),
There is na doubt that the carbonate unit
formed under comparable conditions, typified
by Winter Jake filling from a rising yncontined
aquifer and ensuing summer desiccation. This
observation is enhanced by the fact that the
carbanale unit has a sporadic oecurrence, For
example, vores from some areas such as the
so\thern end of traverse B (Pig. 3) consist
alinost entirely of .carbonate, whilst nearby
cores may be essentially carhonate-free,
Generally speaking, the carbonate unit began
to form during a period of lake shoreline

the chatomite and yellow clay, reflects cither a
decrease in the ammunt of available organic
matter, ar swamping of the organic material by

Significance of the diatonts
Diatom frustules constitute the bulk of the
diatomite unit and also oceur in notable num-
bers in the sapropel, They are present in lesser
quantity in the basal sand and elay, yellow
clay, arkasie sand and black mud units and
are absent from the carbonate and evaporite
Units,
Diatom species are sensitive to depositional
conditions such as water temperature und
salinity (Koiva 1976). From this viewpoint a
preliminary examination of diatoms from the
Cooke Plains Embayment sediments was
carried out (D, Thomas, pers. comm.).
Although additional work is required, the
initial study suggests that these diatom-bearing
sediments were deposited from water having
a Variety of salinities ranging from essentially
fresh to a little less than normal marine, A
general trend was detected in individual units,
from fresher waters at the Lake Alexandrina
end of the embayment to more saline near the
eastern (inner) extremity, implying greater
evaporative concentration of waters in more
restricted areas, Stratizraphically, there appears
to be an upward-freshening trend through the
sapropel to the top of the diatomite, although
these units were both deposited under relatively
low salinity conditions. The yellow clay unil
overlying the diatomite contains diatoms, which
Suagesty a subsequent increase jn salinity to
brackish-marine, This increase is interpreted
to be due to progressive restriction of the
embayment during its most extensive phase by
sediment infilling, and finally by chenier
development. Tt could also be due to seawater
access to the estuary at the height of the Holo-
cene marine transgression, The carbonate unit
does not contain obvious diatom frustules,
possibly due to dissolution of these by alkali
Wadler in the pans. However the black mud
unit of the Central Basin has un assemblage
which denotes a subsequent low-salinitv phase
in that locality. possibly reliled to «# more
humid climatic cyele.

approximately 6500 radiocarbon years age
fvon der Borch, 1976, ANU 1415 and 1416).
The age of this maximum coincides with the
previously mentioned radiocarbon date on the
sapropel anil, However, it also coincides with
a World-wide mid-Holocene humid period
which existed SQOON—S000 vears azo. Elsewhere
in southern Avetratia this period is charac-
tered by wnilarped tukes (Bowler vt al 1976),
This suggests that enhanced run-off due to
the higher humidity may have increased Lis-
charge of the River Mufray, thereby causing
or gugmenting the expansion of Lake Alexan-
drina, Further work will be required before
(he exact nature of this phenomenon can be
documented fully, but it may have been due to
a fortuitous combination of both high sealevel
and higher river discharge.
As lake water level rose, reworking of
Pleistocene sandy soils overlying the calerete
surface resulted in the hasal sand and clay unit,
Fatrophication of the embayment waters
followed, Related to this event is the sapropel
unit which at least in part formed 6900 years
uvo (Fig, 4A). Restriction of the sapropel to
deepest portions of the three basins shown in
Fiv. 2 suguests the possibility of stratification
of lake waters at this time, resulting in oxygen
depletion of bottom waters and consequent
preservation and bacterial modification of
organic matter in a manner similar to that
deseribed by Twenhofel & McKelvey (1941).
An alternative and perhaps more acceptable
explanation may be that the lake reached its
maximum depth at this stage, in response to
the Mid-Holocene humid period. Deeper water
(several metres) und suspended River Murray
sediment could have inhibited photosynthesis
in all but near-surface levels, resulting in low
oxygen levels and accompanying preservation
of algal material on the lake floor to form the
relatively pure sapropel depasit,
Shallowing of lake waters at the close of the
mid-Holocene humid period may have even-
tually enhanced oxygenation of bottom waters,
resulting in the destruction of much of the
subsequently deposited organic material. Dia-
toms would then have been able to dominate
the sediments ta form the diatonyite unit (Fig,
4B), whose significant clay content was
possibly derived from inflow of river water
with its suspended sediment load,
The widespread yellow clay and related
arkosic sand units mark the maximum stand
of ancestral Lake Alexandrina and the end of
the transgressive phase (Fig, 4C). Water levels
as high as 2,7 m above present mean sealevel
are indicated by the cliffs cut in the Pleistocene
culcrete around the northern embayment shore-.
line, The arkosic sand most likely formed as
a Hood-tide delta, rapidly building the embay-
toent sediments up to water level, The
simultancously deposited yellow clay likely
comprises River Murry suspended load sedi-
ment which was deposited in less energetic
regions of the embayment, A progressive
HOLOCENE STRATIGRAPHY OF AN EMBAYMENT OF LAKE ALEXANDRINA 77
increase in water salinity, detected in the dia-
tom flora of the yellow clay unit, may have
been due to relatively free access of marine
waters to the lake at the peak of the post-
glacial transgression, through passes in the
developing Younghusband Peninsula barrier.
This increase in salinity would undoubtedly
have caused increased flocculation and deposi-
tion of suspended River Murray clays which,
during fresher periods, would most likely have
been carried in suspension out to sea.
Regressive phase
The regressive phase of the Cooke Plains
Embayment is represented by the carbonate
and evaporite units (Fig. 4D). The carbonate
unit formed in shallow ephemeral alkaline
lakes fed by seasonal groundwater inflow. As
stated earlier, carbonates developed most
readily along the southern margin of the
embayment adjacent to the high Pleistocene
dune where groundwater inflow from dune
aquifers was enhanced. During shoreline
regression the carbonate environment dia-
chronously migrated to the west to localities in
the Lower Basins where it is precipitating
today. The evaporite unit, comprising gypsum
and halite, developed in the Central and Upper
Basins in areas most remote from the present
Lake Alexandrina and in a region of seasonal
groundwater discharge and evaporation. Like
the carbonates, evaporites are also forming at
the present day in some areas.
The black mud unit, with its freshwater
diatom flora, resembles the organic-rich mud
which is being trapped around reed-beds in
present day freshwater Lake Alexandrina, It
exists in the Central Basin near the top of the
stratigraphic sequence, where it occurs in place
of the carbonate and evaporite units, Such a
relationship is most easily explained by a short-
lived period of increased humidity which
resulted in the formation of a freshwater
swamp in the Central Basin. Carbonates and
evaporites could have continued to form in
pans marginal to this swamp. A period of
relatively high stream discharge 3500-1800
years ago has been suggested by Williams
(1973) to explain some aspects of alluvial fans
stratigraphy in the Lake Torrens region of
South Australia. This humid period may
correlate with the formation of the black mud
unit, Alternatively, its formation may have
been synchronous with a period more humid
than the present one, centred at about 1000
years ago. At this time Lake Keilambete in
western Victoria had a water level significantly
higher than the present level (Bowler et al.
1976).
Chenier and lunette formation
The two cheniers (Fig. 2) across the mouth
of the Cooke Plains Embayment are built from
siliceous sands provided by long-shore trans-
port within the lake. They overlie calcitic muds
which are thought to be correlative with the
carbonate unit. The older, inner chenier was
constructed when water level was. slightly
higher than the present lake level. The outer
bar is probably still forming. The fact that the
inner chenier sits on a clayey unit which con-
tains carbonate similar to the carbonate unit
described earlier suggests it to be a relatively
recent feature. formed following most of the
sedimentation in the Embayment. A period of
lake level stillstand or increased storm activity
may have existed to enable littoral transport to
construct the sand spit. Following this, a
relatively rapid but slight (tens of cm) drop
in the lakewater to its present level occurred.
The two well-defined gypsum lunettes at the
eastern extremity of the embayment are diffi-
cult to date on existing evidence. Bowler
(1971) notes double lunette dunes around
playa lakes throughout southeastern Australia,
and provides convincing evidence that they
formed by wind deflation of evaporite pans
during drying stages following humid climatic
cycles, If the luncttes are correlative with those
described elsewhere by Bowler (1971), then
they are of the order of 25000 years old.
formed during the regional humid to arid
climate changes at that time. On the other hand
it is possible that at least the lunette nearest the
lake may be considerably younger, and related
to Holocene sedimentation in the Cooke Plains
Embayment. Obviously further work is
required to clarify this matter.
Regional correlations
Stratigraphic studies and surveying of core
sites to mean sealevel (using Australian Height
Datum benchmarks) imply that a major inter-
connected body of water existed in the area
up to 5000 or 6000 years ago, during the time
of maximum level of Lake Alexandrina. The
water body in question extended from lakes
Albert and Alexandrina and their stranded
flats, via the north and south lagoons of the
Coorong, to regions now occupied by stranded
ephemeral carbonate lakes adjacent to the
southern extremity of the Coorong Lagoon.

Cores taken from all of these widely separated
areas contain a saprope] unit in deepest
portions of the basins (Taylor & Poole 1931;
von der Borch 1965, 1976, Milne! 1973, Plush
1974, Lock" 1974, Dunstan! 1976). Radio-
carbon dates (Gak 6007 and 6008) made on
sapropel from below a carbonate mud sequence
in two of the alkaline lakes adjacent to the
southern Coorong Lagoon, give ages of 8000
+ 470 and 6600 + 210 radiocarbon years re-
spectively, the last of which is cquivalent in age
to that of at least a portion of the Cooke Plaing
Embayment sapropel. Quite clearly a major
freshwater lake system existed over the area
during the mid-Holocene humid period, which
coded 5000 years ago. This lake presumably
received its water from the River Murray, At
the onset of less humid conditions subsequent
ta 5000 years ago the lake level fell, As a
result the marginal areas became stranded and
in some areas evolved into discrete ground-
water-fed alkaline or saline evaporite lakes,
interrupted by a temporary return to freshwater
conditions possibly a thousand years ago, Such
a climatic evolution is consistent with that
proposed by Bowler ct al, (1976) trom studies
of Lake Keilambete in western Victoria,

A revised, jiustrated generic key to mature nymphs of the Ephemeroptera (mayflics) of
Australia is presented. A résumé of dingnostic characters of the five familics represented in
Australia is also given, and a list of the 19 genera described from Australia is included.
Introduction
Although the Ephemeroptera, or mayfiies,
are abundant in the Australian freshwater
environment, their classification below the level
of Family is unreliable. The majority of the
systematic study on this Order has been con-
cerned with the adult stage. with approximately
70 species being described. Of these species
only 33 have been associated with their respec-
live nymphs, This situation, although similar
to that found in the rest of the world
(Edmunds & Allen 1966), is anomalous in that
nymphs are by far the longest living stage, and
they are often abundant in benthic saniples
from permanent freshwater habitats, The
inability to identify animals abundant in the
benthos limits the amount of information that
is available on the benthic community.
Williams (1968) recognised this problem
and provideda key to the genera of Ephemero-
ptera nymphs, noting that some difficulties
would oceur in its use, After examining
numerous collections of nymphs and adults,
from all parts of Australia, a revision of
Williams’ key to genera has been prepared.
Comments ind eriticisms from biologists upon
this revision will enable further improvements
to be made, resulting in reliable identification.
There has been debate about the classifica-
tion of this Order, especially of the families
Raetidae and Siphtonuridae, Riek (1970)
placed the two groups as subfamilies Siphlo-
nurioae and Bactinae in the Bactidue. In 1973,
Rick refers to the Siphlonuridae and Bactidae
as separate families. Recent reviews of the
phylogeny of the Ephemeroptera (Edmunds
1975: Edmunds, Jensen & Berner 1976) also
consider these as separate families. This classi-
fication (used also by Williams 1968) has been
maintained in this paper, The three other
families recognised in Australia to date are
Leptophlebiidae, Ephemerellidac, and Caeni-
dae.
Four genera in the Leptophlebiidae have
been described from adults only and no formal
description of nymphal material has been
made. These genera are, Atalomicria Harker,
Kirrara Harker, Thraulophlebia Demoulin, and
Ulmerophiebia Demoulin, Of these all except
Thraulophlebia have been included in a study
of adult and nympha!l morphology and phylo-
geny by Tsui & Peters (1975), and nymphs of
two (Atalomicria and Kirrara) have been
illustrated but not described by Rick (1970),
Therefore, these genera cannot be incorporated
in this key, but a mention of the characteris-
tics which distinguish them, as illustrated by
Riek, is included.
Atalomicria nymphs “have conspicuous.
preatly elongated maxillary palpi” (Riek 1970)
which extend well beyond the front of the
bead. and in Avrrarva “the abdominal gills have
ventral lobes which combine to form a large
suction disc” (Riek 1970).
A résumé of the five families of Australian
mayflies is included here. The number of
species mentioned refers to published material.
There are undoubtedly numerous as yet unde-

Family LEPTOPHLEBIDAE
Nymphs large, slender, dorse-ventrally
flattened with prognathous head, maxillary and
labial palps 3-segmented, Abdominal segments
\-7 bear lateral gill; three long caudal filaments
with whorls of short sctae at apex of cach
segment,
The nymphs are found m most permanent
freshwater habitats from standing waters to
fast flowing streants,
The Leptophiebiidae is the dominant maylly
family in Australia with 43 described specics
in eight genera. Of the 43 species only 16 are
described from both adult and associated
nymphs, A list of the genera and the number
of described species is included, while the

elytriform gill cover, covering remaining pairs
which bear long tracheal filaments. Hind
corners of abdominal segments produced inte
small backward puinting projections, and there
are three caudal filaments with whorls of short

The nymphs are found on the undersurface
of rocks and wood on the bottom of ponds
and standing pools, as well as in slow to
moderately fast flowing streams,
Only one genus is recorded in Australia.

Introduction
In his revision of the Genus Propallere.
Stock (1975) recorded its distribution as Japan,
southeastern Asia, southern and southeastern
Africu, Madagascar and Sierra Leone, Three
new species described here increase the total
io ten and establishes a new record from Aus-
tralian waters, The Australian material ts
recorded from the shallow waters of Iwo
diverse regions: the tropical waters of Quecns-
jand in the north, and the southern temperate
waters of Victoria. Propallene saengeri wits
collected using a Van Veen Grab during ben-
thic surveys at the mouth of the Calliope
River, Gladstone, Queensland. for the Queens-
land Blectricity Generating Board; P. cyathies
was collected using $.C.U.B.A. during an off-
shore benthic survey for the Latrobe Valley
Water and Sewerage Board southwest of Sea
spray on the Ninety Mile Beach, and P, vagus
was collected using $.C.U.B.A, in the vicinity
of Port Phillip Heads. Institutions in which

southwest of Seaspray for the lalrobe Valley
Water and Sewerage Board, Examination of
347 adult tndividuals showed ati extremely
high percentage of fertile specimens; 92.9% of
the males were ovigerous and 96.8% wf the
lemalcs were gravid, Only three specimens of
& cyathus were recorded from two previous
surveys of the same station in March and
August, 1977. In March 1977, one ovigerous
male and two juvenile males were collected.
No specimens were recorded fram the latler
survey. Such a high percentage of fertile speei-
mens in November suggests 4 cyclic breeding
pattern, and the complete absence of speci-
nuns just four months earlier, may indicate a
migratory response to their reproductive
yetivity, Hydrological studies by Newell
(1961) indicafe a seasonal reversal of current
patterns in this region, and jt is. probable thal
the extent of migration is largely dependent on
the Bass Strait current system, In many in-
stances specimens were heavily encrusted with

la the absenee of further records of the

locate the holetype (Stock 1974), morpho-

I am satisfied, however, that the [following
features are sufficient to justify the specific
status of P. vapes: larger size (e.g, ¥ leg 3 o!
P. similis is 4,79 mm, that of Po vagus 7.4%

ferous second palp segment (e.g, Barnard

7 times its basal diameter, with a small group
of setae distally: P. vagus 54 times. and with
a dense fringe of long setae distally), stronger

most specimens had attached themsclyes to
small fragments of drifting detritus, the only
identifiable piece of which wax a portion ot a
colomy of the arboresceat bryozoan Corni-
copina erandis (Busk).
The specific name, vaews (wandering)
alludes to the situation in which the specimens
were observed when collected.
The collection comprised only three males,
two af whieh are sub-adult, and eleven
females. The single mature male had rem-
nants of cement adhering to the fifth oviger
segment indicating that eggs had been carried,
Ol the 1] females, 10 were gravid, und the
Jow pjumber, or complete absence of eves in
some legs, suggested that eggs had recently
been deposited.

Summary
TEALE, Grattam §, (1979) Revision of nomenclature for Palaeozoic intrusives of the Mount
Painter Province, South Australia, Trans. R. Soc. S. Aust. 103(4), 95-100, 31 May 1979,
‘The term Mudnawatana Granite has been used to describe two large bodies of Palaeozoic
granite in the Mount Painter Province of South Australia. The two intrusive bodies are petro-
graphically and geochemically distinct.
It iy suggested that the term Mudnawatana Granite be changed to Mudnawatana Tonalite
and applied only to the pluton in the Mt Babbage Block. It is proposed that the other large
pluton which intrudes the Mt Painter Block be termed the British Empire Granite. A third,
previously unmapped Palaeozoic intrusive type is designated the Gordon Springs Granodiorite.
Chappell & White (1974) have used geochemical, isotopic, mineralogical and textural
criteria to distinguish granite types with a basic to intermediate igneous protolith (“T-type”)
from those with a metasedimentary protolith (“S-type”). The Mudnawatana Tonalite and
Gordon Springs Granodiorite do have many charucteristics indicative of “I-type” granitoids:
the British Empire Granite, however, exhibits most of the characteristics ascribed to “S-type”
granitoids.
Introduction
Previous mapping within the Mt Painter Pro-
vince of South Australia (Coats et al. 1969)
has separated a “Younger Granite Suite” from <4
the older (Carpentarian) metamorphic base- W
ment complex. This “Younger Granite Suite”
includes minor biotite and muscovite pegma-
tites, aplites, potassium-rich pegmatitic granite
and albitites but is predominantly composed of
the Mudnawatana Granite (Bowes 1953). The
term Mudnawatana Granite was first applied
by Bowes (1953) to the pluton in the MI
Babbage Block (Fig. 1) but has since been
extended by Coats & Blissett (1971) to include
two bodies of granite that intrude the central SS
part of the Mt Painter Block (Fig. 1). SS
According to Bowes (1953) the Mudna- fags: SSG

watana Granite in its type locality is a geet COMPLE
medium-grained, equigranular rock consisting ‘
of plagioclase (Ana,), quartz, biotite and [+ ]mwsminassae
microcline, Using a modal analysis he cate-
gorised the intrusion as an “adamellite on the .

the type Mudnawatana Granite because of
their “similar composition, texture and grain
size”. Neither Bowes (1953) nor Coats & Blis-
sett (1971) used chemical data for their classi-
fications Of the intrusives,
This paper presenis the results of a re-
examination of these leticocrati¢ intrusive
rocks. Three distinct intrusive types can be
recognised on geochemical and petrographic
data and a revision of present noimenclature 1s
recommended, The terms tonalite, granodiorite
and granite as used here conform to the
recommendation of the LU.G.S, Subcommis-
sion on the Systematics of Igneous rocks
(Streckeisen 1976).
Field Relationships
The Gordon Springs Granodiorite occurs as
small stocks and crosscutting dykes (Fig, 2)
which intrude augen gneiss and sillimanite
gneiss in the Radium Creek area and migma-
titic gneiss in the Paralana Hot Springs area.
It is similar in colour and texture to the Mud-
nawatana Tonalite although usually it is more
fine-grained. No contact metamorphic features
are evident.
In the upper reaches of Radium Creek, the
Granodiorite, at its type locality, intrudes a
zone of strongly lineated sillimanite gneiss
which was developed during the last pre-Ade-
laidean deformational event. The weak folia-
tion evident in the granodiorite cannot be attri-
buted to this deformation and it is suggested
that the fabric is a result of the later Dela-
mertian orogeny; the implication is that the
granodiorite was emplaced prior to the Dela-
merian orogeny. Dating of the Gordon Springs
Granodiorite, using the Rb/Sr isotopic tech-
nique, is currently being undertaken.
Ficld relationships of the Mudnawatana
Tonalite have been adequately described by
Bowes (1953) and Coats & Blissett (1971).
The tonalite is intrusive into deformed Carpen-
tarian granitoids and has caused minor recrys-
tallisation of pre-existing gneissic textures, No
other contact metamorphic phenomena have
been observed. The weak foliation present
implies that it has been deformed after its
emplacement,
The British Empire Granite has intruded as
large semi-conformable sills which dip shal-
lowly towards the west, The non-foliated, and
therefore probably post-Delamerian intrusive,
has numerous pegmalitic apophyses, all of
Which occur along the western margin (or
roof) of the intrusive. According to Coats &
Blissett (1971) the granite contains abundant
xenoliths and rafts of reeling Heights
Quartzite; they suggest that the granite is pre-
orogenic on the grounds of its apparent struc-
tural Tepetition in the Paralana Hot Spring
area, There are, however, no yvranitoids similar
fo the British Empire Granite in that area.
It is proposed that the type Mudnawatana
Granite be reclassified as the
Mudnawatana

In the southern Mt Paitter Block previously
unfecognised intrusives occur as sniull stacks

Petrography
The Gerdon Springs Granodiorite
The Gordon Springs intrusive is a fine
grained, equigratula’, grey biotite eranadiorie
whieh is restricted in outcrop Lo the southern
part of the Mt Painter Block (Fig. 3) The
granodiorile consists of sodi¢ andesine (Any.)-
microcline, biotite and quarie with accessory
magnetite, monazite, apatite and rare rutile
and zircon, Plagioclase (~1,5 mm) is com-
plexly yoned and twinned and has heen de-
formed and recrystallised alony its grain houn-
daries, Quartz exhibits Wridulose extinction and
sub-grain development. Apatite (0,05 mm)
and zircon are usually associyted with biotite
whereas monazite occurs randomly distributed
throughout the rock. Some larger apatite grams
(up to 0.3 mm) occur as inclusions in plagio-
vlase. Biotite composition can be used to
characterise the different plutons, using Wl %
Al.O, and the ratio 100 My’ Mg + Fe. Biotile
in the Gordon Springs Granodiorite ts red
brown in colour and contains 16.5 wl %%
Al.O. and has a 100 Mg/Mg+ Fe of 56
(mean of 4 unalyses), Muscovile occurs in the
more corundum normative variants, with
secandary muscovite and sare sub-himinous
amphibole formed during the Delamerian
event.
In Radium Creek, approximately 1 km up-
stream From its junction with Arkaroola Creek,
there is a hornblende-hearing variant of the
Gordow Springs Granodiorite, The rock is
slivhrly coarser than the normal Gordon
Springs (ntrusive and has a grain size of
approximately 2 mm. Brown-green hornblende
is found as single grains throughout the rack
and has a 100 Mg/Mg+Fe of 61 Horn-
blende and hiatite comprise approximately 8%
of the mode with calcie oligoctase, barium rich
micro-perthitic K-feldspar and quartz weeannt-
ing for the remainder. Biotile is yellow-brown
and has a low AlsO., value (12.4 wt %) and
a 100 Me/Me-+ Fe of 72. Although mona-
vile is the dominant aceessory phase in the
hornblende-free variety of the Gordon Springs
Granodiorite it is not present in this horn-
blende-bearing type. The accessory phases in
this small stock are sphene and allaiite (0,08
mm) with rare zircon associated with biotite.
Acicular apatite graits are found iy hath hie
tite and plagioclase with megielife occurring
as discrete grains scattered throughout the
rack,
The Mudnawatana Tonalire
The Mudnawatana Tonalle ws described
petrographically by Bowes (1953) ts a weakly
foliated, medium graited granitoid which in
thin section exhibits deformed and m places
recrystallised quartz, teldspars and biotite. Ir
contains calcic oligoclase, quartz, microcline
and biotite with rare zircon and apatite, Zircon
is found in biotite and is responsible for the
numerous pleochroic haloes that aye present,
Apatite is also confined mainly to biotite and
is usually acicular, No monazite has been
observed. Magnetite 1s follnd as granules
within biotite with no magnetite grains m the
matrix, Plagioclase is more <odic than the
Gordon Springs Granodinrite plagioclase and
is also complexly twinned and zoned. The
average size Of plagivclase prains is 1A min;
however, some plagioclase crystals up to LS
em have heen observed. Plaginclase cores are
usnally teplaced by aggregates of muscovite,
valcite and kaolinne.
The Botish Empire Granite
The British Fmpire Gratite is a fine to
medium grained, light coloured, muscovite-
hearing alkaline granite whieh consists of
abundant muscovite (up to 5 mm), sadiv
plagioclase, mierocline, quatiz and minor bio-
lite, garnet (~O.3 mm), apatite, Huorite anc
rare magnetite. No zifeon, monazite, allanite
or sphene have heen recorded, Pligioclase

usually forms large (up to 1 mm) grains inter-

Geochemistry and Discussion
The Gordon Springs Granodiorite is quite
distinct from both the British Empire Granite
and the Mudnawatana Tonalite in that it con-
tains very high Ba and Sr values and also has
higher values for TiO,, CaO, MgO, Total Fe
and Zr (Table 1). It has a K/Rb ratio (~120)
intermediate between the British Empire
Granite and the Mudnawatana Tonalite and
has a Rb/Sr ratio closer to the tonalite than
the granite. The hornblende-bearing variety of
the granodiorite has a slightly higher K/Rb
ratio (154) and is the only diopside normative
Palaeozoic granitoid (Table 1); all other in-
trusives are corundum normative to varying
degrees. The hornblende-bearing intrusive also
contains magnetite and sphene as the dominant
accessory phases in common with other
“T-type” plutons (Chappell & White 1974;
O'Neil et al. 1977). The hornblende-absent
granodiorite, which is the more common
variant, contains monazite as the dominant
accessory phase, a feature not usually charac-
teristic of “I-type” plutons (Chappell & White
1974). A noticeable distinction between the.
Gordon Springs Granodiorite and the Mud-
nawatana Tonalite is the absence of monazite
in the latter. The granodiorite has between
0.3% and 1.4% normative corundum and mol.
Al,O;/(Na,0 + K,O + CaO) values of less
than 1.1.
The Mudnawatana Tonalite has lower values
of P,O,, TiO,, K,0, MgO, Total Fe, Rb and
Zr and a higher value of Na,O than the
Gordon Springs Granodiorite. Its K/Rb ratio
(275) is much higher than any other pluton
and it has the lowest Rb/Sr ratio of all the
Palaeozoic granitoids (Table 1). Its initial
Sr87/Sr86 ratio of .7045 = .0012 is so low as
to preclude all but an insignificant contribution
of old crustal material.
The “I-type” character of the Mudnawatana
Tonalite and the Gordon Springs Granodiorite
is not marked; however, the mol. Al,O./
(Na,.O + KO + CaO) values of less than
1.1, the high Na,O/K,O ratios (Fig. 4) and
the low initial Sr§*/Sr8* ratio of the Mudna-
watana Tonalite are all indicative of “I-type”
plutons (Chappell & White 1974). Their posi-
tion on the Ab-An-Or diagram (Fig. 5) indi-
cates that they are much higher temperature
melts than the British Empire
Granite.
The British Empire Granite has higher SiO.,
Rb and Nb and lower MgO, TiO,, CaO, Zr,
Sr and Ba than the Mudnawatana Tonalite
and the Gordon Springs Granodiorite. It has
extremely low K/Rb ratios (Table 1) and very
high Rb/Sr ratios. There is a chemical in-
homogeneity within the mass and variation
diagrams exhibit a large scatter, a feature
“S-type”

corundum normative; both features that are
common to “S-type” granitoids. The high value

gram (Fig. 5) verify this, The initial Sr'7/Sr*6
ratio of .7591 + .0146 (J. A. Cooper pers,
comm.) is indicative of “S-type” plutons, albeit
extraordinarily high.
Biotites from the British Empire Granite
have exceptionally high octahedral Al (0.9-1.0
atoms) whereas octahedral Al in biotites from
the Gordon Springs Granodiorite are from
0,30-0,35 atoms. Biotite from the hornblende-
bearing variant of the granodiorite has less
than 0.1 atom of octahedral Al, Albuquerque
(1973) has noted that the composition of bio-
lite is probably a strong indicator of the pera-
PALAEOZOIC INTRUSIVES 99
luminous character of the granite. O'Neil et al.
(1977) show that biotites from “S-type” gra-
nites of the New England Batholith have octa-
hedral Al in excess of 0.6 atoms.
In Fig. 6 analysed samples of the granitoids
under discussion have been plotted in terms
of Al-Na-K, Ca and Fe + Mg. All samples
of the British Empire (“S-type”) Granite fall
in the field of plagioclase + muscovite + Mn-
rich garnet, Whereas all but one of the Mudna-
watana Tonalite and Gordon Springs Grano-
diorite (“I-types”) samples fall into the field
of plagioclase + biotite or plagioclase -- bio-
lite + hornblende. The separation of the tona-
lite and granodiorite from the granite can
also be observed in Fig. 4 with the more sili-
veous British Empire Granite having overall
lower Na,O/K.0O ratios, with the tonalite and
the granodiorite having higher Na,O/K,O
ratios.
Conclusions
From petrographic and geochemical evi-
dence it is suggested that the term Mudna-
watana Granite be changed to Mudnawatana
Tonalite and be applied only to the Palaeozoic
intrusive mapped by Bowes (1953) and Coats
& Blissett (1972) in the Mt Babbage Block
(Fig, 1). The term British Empire Granite is
proposed for the “S-type” intrusive body con-
tained within the central section of the Mt
Painter Block (Fig, 3), and the term Gordon
Springs Granodiorite for the previously un-
mapped “T-type” intrusive found throughout
the southern regions of the Mt Painter Block,

STRATIGRAPHY OF THE EARLY CAMBRIAN EDEOWIE LIMESTONE
MEMBER, FLINDERS RANGES, SOUTH AUSTRALIA
BY P. S. MOORE
Summary
The Edeowie Limestone Member comprises a thin unit of buff-coloured, flaggy weathering,
dolomitic limestone. As previously defined in the literature, the member was assigned to the Lower
to Middle Cambrian Billy Creek Formation. However, on both stratigraphic and sedimentological
evidence, the sequence is considered to relate best to the limestones of the Hawker Group. The
Edeowie Limestone Member is therefore reclassified as the uppermost member of the Orapinna
Shale. The definition of the lower boundary of the Edeowie Limestone Member is also revised.

dolomitic limestone, As previously defined in the literature, the member was assigned to the
tower In Middle Cambrian Billy Creek Formation. However, on both stratigraphic and
sedimentological evidence, the sequence is considered to relate best to the limestones: of the

Introduction
In their summary description of the Lower
Cambrian stratigraphy of the western Flinders
Ranges, Dalgarno & Johnson (1962) defined
the base of the Billy Creek Formation as. “xs
two foot thick fossliferous limestone which
varries /Tyolithes, unidentified brachiopods and
occasional trilobite fragments”. They con-
linued: “This bed o¢curs ten feet or less below
4 prominent thin bedded and laminated dolo-
mite which is an excellent marker throughout
the area discussed”. Between the fossiliferous
limestone and the laminated dolomite there
ate greyish green silty shales. Thus, as
previously defined, the Edeowie Limestone
Member comprised the entire sequence from
the base of the fossiliferous limestone to the
top of the Maggy dolomite. In some arcas, such
uy near the Bunyeroo Gorge and at Mern-
merna, this definition meant that the lower
hal! of the member comprised dominantly
greyish green shale, identical in character to
the underlying Oraparinna Shale. The present
contribution redefines the base of the Edeowic
Limestone Member so as to exclude this basal
shale—carbonate sequence (Fig. 4), which ts
therefore included in the Oraparinna Shale,
sere stricto,
Although the Edeawie Limestone Member is
represented in outcrops along the Heysen
Range, at Mernmerna and in the southern part
of the Wirrealpa Basin!, it is absent from many
other areas (Fig. 1). Thus, by including the
Edeowie Limestone Member as part of the
Billy Creek Formation, one may infer that the
shales of the basal Billy Creck Formation are,
in some areas, laterally equivalent to the
Edeowie Limestone Member, or else that the
base of the Billy Creek Formation is locally
disconformable. Such a siluation is considered
by the author to be unlikely, for reasons dis-
cussed below. In addition, B, Daily (pers,
comm. 1977) had originally included what was
later termed the Edeowie Limestone Member
in the type Oraparinna Shale.
Redefinition
Due mainly to the sporadic outcrop of the
Canibrian sequence in the Flinders Ranges.
the Edeowie Limestone Member cannot he
traced unequivocally into its lateral strati-
graphic equivalent, However, two outcrops, in
the central and southern portions of the
Wirrealpa Basin, support the author's view that
the Edeowie Limestone Member passes
laterally into other units of the Hawker Group,

Fig. |, Location map, showing outerap of upper
Lower to lower Middle Cambrian strata
in the Flinders Ranges. The FEdeowie
Limestone Meniber occurs in (he southern
portion of the Wirrealpn Basin, at Mern-
mera, and along the Heysen Range
(Brachina/Bunyeroo) where ut underlies
fedbeds of the Billy Creek Formation, It
is absent however from several other
vuterops (Mi Frome, Reaphbook Hill, the
northemn and suulliern extremities of the
Wirrealpa Basin, and the Mount Scott
Range),
The Edeowie Limestone Member is shown by
Dalgarno & Johnson (1966) as outcropping
continuously along the Bunkers Range, from
north of Baleoracana Creck to south of Ten
Mile Creek, In the most southern area of out-
crop south of the Ten Mile Creek graben, the
Edeowie Limeston¢ Member is absent and
redbeds of the Billy Creek Formation lic
uncunformably on Wilkawillina Litmestone.
Although outerop is poor in the critical inter-
vening airca, it ts apparent that the Bdeowie
Limestone Member does not thin to a feather-
edge an@ onlap the Wilkawillina Limestone on
the southern flank of the graben, but instead,
Passes southwards with little thickness variation
from evenly laminated limestone into evenly
bedded dolomiti¢ limestone. Interdigitaied with
the dolomitic limestone are two thin tongues of
highly silicified, ?stromatolitic carbonate which
can be traced laterally inte the uppermost
Wilkawillina Limestone. ‘Thus, gy transition
uppears to vecur, from evenly laminated Jime-
stane into stromatolitic limestone on the
southern margin of the Ten Mile Creck praben.
This facies change is related to differences in
Waler depth of the flank of the grshen, with
the highly silicifiled, ?steornstolitic carhonates
deposited in relatively shallow water,
An identical situation occurs further north
m the Wirrewlpa Basin, where the Edeowie
Limestone Member passes trom an evenly
fuminated argillsccous limestone in the vicinity
of Baleoracana Creek into a highly silicified,
%stromatolitic limestone mits northernmost
eulcrop, approximately 1 km to the north,
Unfortunately, the sequence in this area is
complicated by faulting and poor outcrop, and
the siheified limestones cannot be traced swrth-
wards along strike, Ten kilometres to the north
however, near the Old Wirrealpa Mine, red
and green shales of the Billy Creek Formation
rest conformably on stromatoliti¢ dolomite of
the Wilkawillina Limestone, Since the Edgowie
limestone Member is present and well
developed only 10 km to the south, the lateral
transition with decreasing water depth trom
laggy Edeowie limestone into stromatolitic
Wilkawillina dolomite is considered jn this case
to be more likely than the alternate transition,
from flaggy Edeowie limestone into shaly, non-
calearcous redbeds of the Billy Creek Forma-
tion,
The Edeowig Limestone Member is also
present along the Heysen Range, where it
thickens towards the south in sympathy with
other units of the Hawker Group, To the north
in the Mount Scott Range, the Hawker Group
is quite thin, and much of the sequence
indicates deposition on a very shallow shelf.
The FEdeowie Limestone Member is absent,
and non-calcareous redbeds of the Billy Creek
Formation rest directly on stromatolitic dolo-
mite of the Ajax Limestone. The contact has
been excavated at a locality approximately 15
km northwest of the main road, and red shales
of the Billy Creek Formation were observed
draping perfecily preserved domal stromato-
lites of the Ajax Limestone. The lack of erosion
ol the stromatolitic domes indicates that the
contact is a conformity or at most, an hiatus
of insignificant duration, ‘Thus, a transition
from the flagegy Edeowie limestone in the
ceutre of the basin, into stromatolitic dolomite
of the basin margins is again considered to be
the mast likely sedimentological interpretation
of the sequence. This view is supported hy the
fact that the stromatolitic dolomite and the
flaggy Edeowie limestone are always mutually
exclusive. Nowhere does the Edeowie Lime-
stone Member rest on synscdimentary dolo-
mites of the Hawker Group,

Group. The outcrop is located approximately
12 km north of Parachilna, and is shown on
the Parachilna 1[:250000 Geological Sheet
(Dalgarno & Johnson 1966). The sequence at
this locality is quite thin and the Oraparinna
Shale, instead of heing an olive green to black
shaly siltstone, comprises a fine-grained
sequence which is reddish in part, and contains
several Maggy limestone intervals up to 2 m in
thickness, These flaggy limestones are similar
in character ta outerops of the Edeowie Lime-
stone Member. This unusual variant of the
Oraparinna Shale is inferred to pass north-
wards into the Ajax Limestone, and southwards
into the more characteristic facies of the Ora-
parinoa Shale,
In outcrops south of the Chambers Gorge,

the Billy Creek Formation rest conformably

increasingly Well bedded in stratigraphically
higher units. The uppermost 6-9 m are domi-
nated by platy to flagey limestones similar
in character to much of the Edeowie Lime-
stone Member, although somewhat less dolo-
mitic. Thus, the Edeowie Limestone Member
is considered by the author to be the lateral
equivalent of the uppermost part of the Mooro-
wie Formation.
The Base of the Edeowie Limestone Member
In the vicinity of Ten Mile Creek in the
Wirrealpa Basin, evenly laminated, flaggy,
dolamitic limestone of the Edeowie Limestone
Member rests conformably on a thick sequence
of Oraparinna Shale (Figs, 5a, 5b). Further to
the south, the Edeowie Limestone Member
tests conformably on thinly bedded, rubbly
Wilkawillina Limestone which intertongues
with the Orapariona Shale in the vicinity of a
biohermal bank (Walter 1965*, 1967). In the

In most outcrops, the Edeowie Linestone
Member is overlain conformably by red and
green laminated shales of the Billy Creek
Formation. The contact is poorly exposed as
the flagey limestone becomes platy and argilla-
ceous, and passes upwards into greyish green
shale. The passage Zone is typically only 10-30

In the three small basins adjacent to Balcora-
cana Creck, the Edeowie Limestone Member
is overlain conformably by a thin sesuence of
pale brown, caleareous, medium-grained sand-
stones attributed to the basal Billy Creek
Formation. The sandstones are cross-bedded
to ripple-laminated, and pass laterally into red

Microsparite (calcisiltite) to micrite (calcil

sandstone are commonly asociated with the
basal portions of graded laminae. The terri-
genous content of this lithology is yenerally
3-8% and rarely exceeds 10%. Although
dominated by subangular to subrounded
quartz, a variety of mineral specics is preseot,
including a very mature suite of heavy
minerals, A high terrigenous clay content is
responsible for the yellowish brown colour
of some intervals, Abundant dendritic pyro-
lusite is a common feature on bedding plane
surfaces (Fig. Se). Mast samples are weakly
dolomitic, and this feature is partly attributed
to a high initial Mg/Ca ratio, associated with
a restricted environment of deposition.

most irregular and in some cases are discon-
tinuous over a metre or less. Individual larmi-
hie are separated by very thin, ferruginous
clay intervals, Terrigenous sand and silt grains

tween successive carbonate laminae, Adjacent
to Balcoracanu Creck and south of the Ten
Mile Creek in the Wirrealpa Basin, the lime-
stone is strongly recrystallised and silicified
(Fig, 5}.
The extreme fissility of this lithology is duc
to the concentration of terrigenous material
into thin laminae. The wavy nature of the
laminae is due in part to the extreme suscepti-
bility of this fissile lithology to the effects of
hillereep and tectonic activity, However, in
most cases the undulose laminations are attri-
buted to sediment binding by algal mats (Fig.
5g). Domed stromatolites. have not been
observed in the Edeowic Limestone Member.
Intraclastic Limestane
In three small sedimentary basins adjacent
(o Balcoracana Creck, thick developments (up
to about 20 m) of the Edeowie Limestone
Member are present, Interbedded with the
fluggy mudstone carbonates are units up to
0.6 m thick, comprising medium grey to pale
arey, intraclastic limestone, This factes is typi-
cally poorly bedded and may be considerably
sandy, Reerystallization to medium or coarse
sparite is common in these units. The intra:
clasts are generally subrounded to rounded.
Micrite or sparite aggregates, up to 5 mm
across. They form a packstone texture in which
the interstices are filled with micrite or, les»
commonly, tmicrosparite,

This lithology is developed in the vicinity of
Balcoracana Creek, particularly io the basal
portions of the member. If comprises thin

Graded bedding, from calcareous sandstone to

sandy beds are loaded on the underlying car-
bonate mudstone. South of Balcorcacana
Creek, small clastic dykes link sandy intervals.
The sandstone dykes are contorted, duc to
post-injection compaction of the carbonate
layers (Fig. 5h),
Tufiaceaus, Silty Linestone
A thin, bright olive green tuffaceous unit up
to 0.4 m thick has been identified from the
Edeowie Limestone Member in several out-
crops south of Balcoracana Creek. Ts tuffa-
ceous origin is principally interpreted from
similar, less altered and coarser-grained litho-
logies in the overlying Billy Creek Formation,
The tuffaceous unit comprises chloritic micrite
and ehloritic, silty mudstone. Quartz fragments

Interpretation of Facies
The absence of fossils in the Edcowie Lime-
stone Member is probably related to the semi-
restricted nature of the depositional environ-
ment, Flaggy limestones and dolomitic lime-
stones (Fig. 5d) are interpreted as having
accumulated on an intertidal to very shallow
marine shelf during a period of regression.
Argillaceous laminae indicate a very minor
although persistent terrigenous influx. Wavy
laminae (Fig. 5g) are considered to be of
algal origin, although domal stromatolites have
not been identified from the Edeowie Lime-
stone Member. There remains the possibility
however that the strongly silicifled and re-
crystallised intervals (Fig. 5f) were originally
stromatolitic.

ber appears to have accumulated in the central
portions of the basin, it is to be expected that
it occurs in a conformable sequence with other
Cumbrian units. Its association with the Ora-
parinna Shale is also consistent with deposition
in the central basinal area, based on the simpli-
fled palaeogeogruphic reconstruction of the
Hawker Group proposed by Wopfner (1969,
Fig, 40). An exception oceurs at Brachina
Gorge (Fig. 7, fourth colurim from the left)
where the Edeowie Limestone Member rests
conformably on a sequence of conglomerates
with silty interbeds. However, in the absence
of palacontological evidence, the conglo-
Merates ure assumed to be the lateral cquiva-
lent of green and grey siltstones of the Ora-
purinna Shale.

thus several interpretations of the sequence are
pessible. Far example, the Ecdeowie Limestone

with a period of nan-deposition and subacrial
exposure at Reaphook Hill. Alternatively, the
Edeowie Limestone Member may have been
deposited in the Reaphook area, but have heen
subsequenily removed by erosion, This hypo-
thesis is considered unlikely however, since
there arc no clasts of the Edeowie fucies in the
conglomerate at the base of the Billy Creek

Faunal Assemblage No. 2, The Edeowie Lime-

deposited in the area due to the region's sub-
aerial exposure at this period of time. Care
must be taken tn interpreting the outerop how-
ever, since the Wilkawillina Limestone is
strongly jointed and dissected by small faults.
The contact hetween the Wilkawillina Lime-
stone and Billy Creek Formation is not
exposed, and a major fault along this boundary
eliminating part. of the sequence remains a
distinet possibility.
Thus, the Edeowie Limestone Member

some cases disconformably on stromatolitic
and fenestral carbonates of the uppermost
Hawker Group.
Conclusion
The Edeowie Limestone Member is re-
defined and reclassified a3 the uppermost mem-
ber of the Oraparinna Shale and thus as. part
of the Lower Cambrian Hawker Group. It
comprises medium grey to buff. flaggy, micri-
tic limestone which is in part dolomitic. In the
vicinity of Baleoracana Creek. thick develop-
ments of the Edeowie Limestone Member
occur in three small basins which underwent
ereater relative subsidence in the Early Cam-
brian. In these regions, the limestone ts slightly
sandy and contains intervals of pale red, in
part recrystallized and silicified, inteaclastic
limestone,

CYCLIC VEGETATION PATTERN IN THE SOUTHERN SIMPSON
DESERT
BY T. J. FATCHEN & S. BAKER
Summary
Local vegetation patterns in the Simpson Desert were objectively examined at seven sites near Lat.
26°S. The vegetation at most sites comprised a continuum of species, usually of regular cycle
across dunes and related to soil stability. Variation in soil type was subordinate to soil in influence
on vegetation.

Local vegetation patterns in the Simpson Desert were objectively examined ul seven sites
year Lat. 26'S. The vegetation at most siles comprised u continuum of species. usually of
regular ¢ycle avross dunes and related to soil stablity. Variation in sail type wus subordinate
tu soil stubility in influence on vegetation,
fifferences were found in the pattern of vegelution between siley due to yariahons in the
species: present, landform und, on Desert margins, domestic stock grazing. The effects of
Womeslic stock grazing suggest that plant cover contributes more to the landscape’s stability
than is thought by some authors,
No regular vegetation pattern was found in the central Desert where dunes were less
regular and Jess mobile than elsewhere, Also Triedia hasedowii was absent, though normally
regarded as typical of the Desert, These characteristics appear more significant in the southern
Desert (hun is reported for the northern part, and represent the main hindscape heterogeneity
found during the study,
Introduction
The vegetation of the Simpson Desert has
received seat attention since the initial study
by Crocker (1945), Further detailed reports
comprise only the single site studies of Boy-
land (1970) and Wiedemann (1971). The
mapping of Perry ef al (1962), Specht (1972)
and Laut et al, (1977) provides information
in broad terms only, much of it derived fram
Crocker’s report, Hence knowledge of the
vegelyuion occupying 150 000 km rests largely
on one traverse and two studies on the mar-
gins
Concern here is with small scale vegelalion
pattern. Local variation in the Desert is known
lo show a pattern concordant with that of soil
stability: the mobile sands of the parallel dune
crests carry «a vegetation contrasting in struc-
ture and species composition to those of the
more stable lower dune slopes aid interdune
corridors, This eyelic sequence is reported
variously as an alternation of discrete Asso-
clations (Crocker 1946; Boyland 1970) or as
continuous variation (Wiedemann 1971),
Crocker lists several variants, of which the fol-
lowing ure most significant, First, in an areca
“west of the Hay River”, the dunes lose some
of their regularity, becoming less mobile, and
the vegetation pattern accordingly alters.
Second, the presence of an Acaclu caimbagei-
dominated Association is noted in restricted
interdune corridors of the eastern Desert, addi-
tional to the usual Zygochloa paradoxa (dune
crest) and Triodia basedowti (slope and corri-
dor) Associations. Despite these variations, the
impression remainy of “a remarkable con-
sistency” (Crocker 1946, p, 249),
The lack of interest in the Vegetation indi-
cated by the dearth of further studies may
well stem from this impression, As well, the
upparent physiographic \niformity of the area
(Madigan 1938) may have led to an assump-
tion of consequent uniformity in the vegeta-
tion,
A series of qtantitative observations are
reported here, taken from seven study sites
istributed across the Desert near Lat 26°S,
and. aimed at further examination of the nature
of the vegetation and the variation In its pat-
tern. The observations also extend sampling to
a hitherio largely unreported area, This is the
first report dealing in detail with the southern
Simpson Desert, and the first in which quanti-
tative information is provided from the Desert

accurate ecological assessment of this large but
poorly investigated part of the continent.
Study site locations and descriptions
The Desert was traversed by vehicle from
West to East in August 1972. A mining
exploration track was followed from Dal-
housie Springs, S.A., to Poeppel’s Corner, and
thence towards Birdsville, Qld, along Lat. 26°S
(Fig. 1). In contrast to previous studies
drought conditions prevailed before and dur-
ing the crossing.
Observations were made at seven sites along
this traverse (Fig. 1). Sites 1-3 had essentially
the same physical characteristics: red regular
dunes 10-15 m high, parallel and evenly
spaced, unstable only at the crests and
separated by sandy or occasionally sandy clay
corridors, In the central Desert at site 4, dunes
were yellow rather than red, lower than at the
previous sites and irregular both in profile and
trend, with stable rather than unstable crests.
The area was homologous with the section of
Crocker’s (1946) traverse, already mentioned,
west of the Hay River. Sites 5 and 6 were in
yellow, regular dunes 15—30 m high, with un-
stable crests and predominantly clay inter-
dunes, while site 7 was in similar dunes
amongst the floodflats of the Mulligan River
(Eyre Creek). Sites 1 and 7 were both grazed
by domestic cattle, watering in the first case
from Purni Bore (an uncapped artesian well
T. J. FATCHEN & SUSAN BARKER
sunk in 1961): and in the second from numer-
ous waterholes in the Mulligan. Other sites
were essentially ungrazed except by occasional
small rabbit populations. Low open woodlands
were found on interdune flats with sandy clay
soils at sites 5 and 6 (Acacia cambagei) and
at site 7 (Eucalyptus microtheca).
Methods
At all but site 6, a single belt transect of
contiguous 4 m x 1 m quadrats was laid across
the trend of the dunes, incorporating at least
one complete topographic cycle. The inci-
dences of all recognisable species encountered
were scored, and the information processed by
Influence Analysis (Lange 1968). Those un-
familiar with this technique should see also
Barker & Lange (1969) and Lange (1971).
Species were identified with reference to the
checklist of Symon (1969).
At site 6, species’ densities were sampled.
The topographic profile was divided into four
categories: dune crest (unstable sand), slip-
slope (steep eastern dune face, semi-stable
sand), backslope (gentle western face, stable
sand) and flat (interdune corridor, sandy clay
loam overlying sandy clay). Three parallel
transects, 400 m apart, were run across a pro-
file comprising three crests, two backslopes
and slipslopes, and one clay flat. Along the
transects were laid 66 20 m x 1 m quadrats at
regular intervals within categories, each at
right angles to the transect. Slipslopes and
crests were more intensively sampled relative
to the ground area they represented, to
approximate the sample sizes obtained on the
other categories. All recognisable species were
scored.
Results
Species’ occurrences
Fifty-two species were found in quadrats
(Table 1) from 87 species observed during the
crossing (Appendix 1), but only nine species
were common to all sites. These were the
grasses Aristida browniana, Enneapogon ave-
naceus, Eragrostis dielsti, Zygochloa paradoxa
and the herbaceous species Atriplex limbata,
Goodenia cycloptera, Salsola kali, Sida virgata
and Tribulus hystrix. Of these, S. kali, E. ave-
naceus and A. browniana were generally the
most abundant, although usually individuals
were dead. Triodia basedowii, supposedly the
“most important plant in the Desert” (Crocker
1946), was absent from sites 4, 5 and 6, and
present only at low frequencies at sites 3 and
7.

Fig. 2. Nodes of association, poles of interaction and assigned Influence Ratings (IR’s) for each sample.
Species numbers are those of Table 1.
Interdune corridors with sandy clay as the
predominant soil type were sampled at sites
2, 3, 5, © and 7, but did not noticeably alter
the array of species encountered except at the
site 3, Here, a low open shrubland of Atriplex
vesicaria was found in one corridor with the
only occurrences in quadrats of the chenopods
A. vesicaria, A, holocarpa, Sclerolaena divari-
cata, Dissocarpus paradoxa, Maireana aphylla
and the Mitchell Grass Astrebla sp. Low open
woodlands on clay flats at sites 5 and 6
(Acacia cambagei) and site 7 (Eucalyptus
microtheca) certainly altered the appearance
of the vegetation but had little influence on the
understorey species list. Trees at these latter
sites were well spaced—at site 6, A. cambagei
occurred in four of 14 quadrats laid in the
woodland, but no trees were found in quadrats
at other sites.
Influence Analyses of vegetation pattern
The nodes of species association and the
assignment of Influence Ratings (IR’s) are
shown in Fig. 2, Small quadrat size and low
replication limited the degree of reinforcing
within nodes—statistical associations tended to
appear as chains rather than webs of asso-
ciated species—but the outline of associations
is clear, Twenty-two species contributed to the
nodes detected, although not all at any one
site. Enough combinations exist, however, to
indicate the pattern of association most likely
to arise if all species were to be present simul-
taneously. Given this, the species of Table 2
are divided into three groups, the first two
having within-group positive association but
with negative association between groups.
Group III represents species which because of
their low abundance or ubiquitous distributions
showed no significant association.
On the basis of their constituent species,
groups I and II conform respectively to the
Triodia basedowii and Zygochloa paradoxa
Associations of Crocker (1946), the former
associated with the stable soils of slopes and
corridors, and the latter with the unstable sand
of dune crests,
In Fig. 3, Influence Ratings (IR’s) are back-
plotted against distance for the individual
nodes at each site. For consistency in presenta-
tion, IR’s have been assigned so that a high

Fig. 3. Influence Ratings backplotted against
Jength of transect for 6 sites in the
Simpson Desert, Breaks in the plots
indicate quadrats with no score. The
uccumpanying topographic profiles ure
diagrammatic only ond are Tauterally dis-
torted (see text).
IR indicates that expression of the influence
favouring group II species. Points on the plot
are evenly spaced for clarity: since the quad-
rats followed the ground contour, the accom-
panying sketches of the transect profile are
distorted accordingly,
In areas of regular, Ungrazed dunes (sites 2,
3 and 5), the major influence of soil stability
is clearly shown by the backplots of the first
node at each site. A pronounced cyclic vegeta-
tion cxists parallel to the topographic cycle and
so to soil stability. Crests and upper dune
slopes display the highest IR’s, with lower
values for the lower slopes and interdunes, A
further node is found at site 2, apparently in-
dicating a secondary influence associated with
the base of the slipslope.
The backplot for node J at site 7 also shows
the influence of soil stability in the same man-
ner, While a second node indicates an undeter-
mined influence ussoviated with upper dune
slopes. There is no evidence in the analysis of
any perturbations which might be aseribed to
i
domestic grazing, although the frequencies at
which species occurred were generally lower
here than elsewhere (Table 1).
At site 1, the transect ran across one dune
into the corridor containing Purni bore and
its drain, on which cattle were concentrated.
As in the previous cases, IR’s increase to a
maximum on the mobile dune crest, then de-
crease along the backslope; but where the
dunce merges into the corridor, near the bore
drain, IR’s again inerease to a level as high as
that found on the crest, The influence dis-
played must be soil stability, given the pattern
of the first half of the transect, hence the rest
of the plot indicates that the corridor-dune
junction has became as unstable as the crest.
Compared with other sites, the vegetation
was relatively uniform in the irregular dunes
at site 4. Overall high TR's along the transect
suggest a high degree of instability, but while

evidence at the site indicated recent deflation
(e.g. wind-cut plinths around the bases of
perennial bushes) the dunes appeared to be
much more stable than at the other sites, with
very little mobile sand present,
Density distributions
Only seven species at site 6 were restricted
entirely to a particular topographic category:
Acacia cambagei, Tragus australianus and Di-
crastylis costelloi on clay flats, Calotis erinacea
and Dodonaea attenuata on backslopes, and
Crotalaria novae-hollandiae, Ptilotus latifolius
and Zygochloa paradoxa on mobile dune
crests. Although other species showed a pre-
ference for a particular category, considerable
overlap occurred. A continuous gradient in
species’ incidence and abundance relative to
the categories is in fact displayed by Fig. 4, in
which the species restricted to flats and crests
respectively represent the two extremes of the
gradient. (C. erinacea and D. attenuata do not
appear to fit in the sequence, but this may
result from minimal abundances—see Appen-
dix 2.)
Essentially, the findings replicate the results
of analyses already given. Most species distri-
butions relate to the primary influence of soil
stability in the manner expected from the In-
fluence Analyses. Two exceptions are Era-
grostis dielsii and Goodenia cycloptera which
at this site show a preference for stable and
unstable soils respectively.
Discussion
The nature of the communities
The continuous variation highlighted by
analyses supports Wiedemann’s (1971) con-
tention of a vegetation continuum along the
dune-interdune cycle rather than a separation
into more-or-less distinct associations as pro-
posed by Crocker (1946) and Boyland (1970).
The continuum relates directly to soil stability,
the major and often only influence detected.
Further, the type of substrate appears to have
little effect on the expression of this con-
tinuum. Clay-dominated soils in interdune cor-
ridors at sites 2. 3, 5 and 7 introduced no per-
turbations to plots of the influence, and only
at site 3 was the array of species present sig-
nificantly altered by the increased soil diver-
sity. Species restricted to clay soils at site 6
appear to represent more an extreme of a
sequence encompassing both sand and clay
soils than a group in their own right, Thus
even the Acacia cambagei woodlands at sites
5 and 6 could be considered as part of the one
continuum rather than a distinct Association,
despite the major and obvious differences in
substrate and appearance. Separate classifica-
tion and mapping, not only of dune Associa-
tions but also of these woodlands, may be con-
venient for rapid and subjective appraisal but
misleading in terms of the system’s operation:
the trees catch the eye but are unlikely to be
exerting much influence on the rest of the
vegetation because of their wide spacing (see
also Wiedemann 1971).
Wiedemann (1971). as well as demonstrat-
ing the existence of the above continuum at his
study area, also defined a number of “habitat
types”. Some support for this curiously ambi-
valent reclassifying of the vegetation might be
seen in the present study, in that the influences
expressed by node 2 at site 2 and node 2 at site
7 may correspond to his “lower slope clayey
sand” and “mid-slope clayey sand” habitats.
However, the results given here show that
these variations are minor indeed by compari-
son with the over-riding influence of soil stabi-
lity.
Variation in vegetation pattern between sites
The cyclic pattern in the vegetation is clearly
not consistent across the Desert. Three sources
of variation are found; in the species present
at any one site, in landform, and in the impact
of domestic stock, Much of the first source
may stem from differences in the levels of
sampling replication or in time since last plant
growth, but differences due to varying distribu-
tions on a biogeographic scale were also noted.
Although a discussion of the last is beyond the
scope of this paper, the absence of Triodia
basedowii from the central Desert sites war-
rants mention in view of the reported import-
ance of the plant. In the western Desert, 7.
basedowii is the most frequently encountered
perennial, and Crocker (1946) and Wiede-
mann (1971) indicate its significance as an
influence on other species present. Hence
changes in the distribution of associated
species would be expected to accompany its
disappearance.
The absence of a clearly defined vegetation
pattern at site 4 reflects differences in land-
form between this and other parts of the
Desert: differences which are not confined to
the southern Desert but apparently extend to
the latitude of Crocker’s crossing. The results
are confusing: the site showed at the same
time evidence of recent deflation and an ab-
sence of mobile sand, while analysis of the

ALOCOSTMA NEW GENUS (NEMATODA: TRICHONEMATIDAE)
BY PATRICIA M. MAWSON
Summary
Alcostoma is related to the genera Macropostrongylus and Macroponema. It is distinguished by the
presence of longitudinal striae in the anterior part of the lining of the buccal cavity, and by the very
distinctive cylindrical submedian cephalic papillae. A diagnosis is given of the new genus, as well
as a partial redescription of the type species, Cyclostrongylus clelandi.

(1979) Alocestoma new genus (Nematoda: Trichonematidac), Trans, 2K,
Soe, So ust W305), 123-126, 31 August, 1979,
Aloecostama is reluted to the genera
Macropostrongylus and Macroponema. It is
distinguished by the presence of longitudinal string in the anterior part of the lining of the
buccal cavity, ynd by the very distinctive cylindrical submedian cephalic papillae, A diagnosis
is given of the new genus, as well as u partial redescription of the type species, Cyclostrongylus
elelandi.
Introduction
Cyclostrengylus Johnston & Mawson was
revised’ by Mawson (1977), C. cleland? being
noted as belonging to an undescribed genus.
This species is now redescribed, and proposed
as the type of a new genus Alocostoma, New
material is now available; though not nu-
merous in any one host animal, specimens
have been taken over a wide geographical
range and from two host species.
Alocostoma gen. noy,
Trichonematidac; Small worms; anterior end
with well developed cuticular collar, sub-
median cephalic papillae cylindrical, truncated;
circumoral cuticle aiid lining of anterior buc-
cal cavity fincly striated; buccal capsule lightly
chitinised, its shape mobile; oesophagus long
and slender, with terminal bulb, Male: bursa
not joined ventrally; ventral rays together,
ventro-lateral rays divergent from other
laterals, externd-corsal rays arise with laterals,
divergent from them; dorsal ray bifureates,
euch branch giviog off lateral stem; spicules
alate, gubernaculum present. Female: tail
conical, vulva close to anus, ovijectors
opposed, parallel to body length. Parasitic in
muacropodid marsupials,
Type species; Cyclostrongylus clelandi John-
ston & Miwson.
Alocestoma most closely resembles Macro-
postrongyvlus, Yorke & Maplestone, 1926 and
Macroponema Mawson, 1978 which have a
long oesophagus with a terminal bulb, the buc-
cal capsule not strongly chitinised, and lips and
leaf crown absent, It differs in the shape of the
buccal capsule and of the cephalic papillae.

anterior end.
Wide, thick cuticular collar around anterior
end pierced around its periphery by cephalic
papillae and amphids. Cepholic papillae of dis-
tinetive shape: cylindrical, abruptly truncated
distally, and with small depression in. centre
of free end, Area around mouth finely striated
radially, and strme continue into anterior part
of buceal cavity as well marked Jongitudinal
lines. Labial collar can be raised as narrow
frill around mouth or depressed below level of
outer cephalic collar, not comparable with leat
crown as it appears in Cloacina spp, and Mrr-
shida spp.. but similar to labial fringe present
in Papillastrongylus labiatus Johnston & Muaw-
son (1939a) and labial Mange in Mueropo-
nema spp. (Mawson 1978), Shape of mouth
varies—round, elongate. or pursed (Fig. 4),
More or less cylindrical buccal capsule so

Ocvsophagus long, cylindrical with clongate

lobes not clearly demarcated, and short ventral
lobes not joined; genital cone small, conical,
with lateral swellings and with accessory cone
of two short bilobed processes. Figs 6-8 show
the shape of the bursa and the arrangement of
the bursal rays in specimens from Macropus
riganteus and in those from M. rebuyiny in
N.S.W, In miles from M, rebustus from W.A,
the dorsal lobe is Jonger and the dorsal ray
correspondingly clongated (Figs 9, 10).
Female body tapers in region of vulva, and
again near tip of tail. Length of vagina varies,
in specimens from eastern Australia it is
shorter than in most of those from W.A, In all
specimens there is a distinet anterior caccum
from the point of origin of vagina (Fig. 11).
No specimens held eggs in the vagina,
though these were present in the uteri, In three
specimens eggs had been laid into a brown egg
case, still attached to the worms. These eggs
measured 105 x 50 jm, were thin shelled, and
appeared not to have divided,
Unless otherwise indicated, specimens
figured were from M. robustus, Rivertree,
N.S.W. These were more numerous than those
from the type host in Victoria, and were col-
lected much closer to the type locality.
Measurements of the specimens examined
are shown in Table 1; those of specimens from
different hosts and localities are shown
separately; allhough the dorsal lobe and ray is
longer in those from W.A.. there does not
appear to be grounds for the proposal of a
new species. Measurements of specimens from
the two hosts in W.A, are given separately, as
it seemed that one collection was of younger
worms—the body is shorter and no eggs were
present in the uteri.

genetic unplications of the findings are discussed.
Introduction
There is controversy over the phylogenetic
relationships of Australian native rodents
(Tate 1951. Simpson 1961; Watts 1974;
Baverstock ¢f al, 1977b; Baverstock ef al,
1977c) although all species are considered
members of the Muridae.
On the basis of a wealth of morphometric
data, Tate (1951) classified the Australo-
papuan rodents into two subfamilies: the
Hydromyinae, which he considers diverged
from an ancestral murid or even cricetid stock
and is represented in Australia by Neramys
and Mydremys, and the Murinae whieh in-
cludes all other genera. In the Mutinae he con-
siders that Psendomys, Leporillus, Masto-
coms, Notomys, Zysomnys and Conitarus
evolved from one afcestral stock, whereas a
more modern group branched off from a stem
leading to Rattus and gave rise lo Meloiiss
and Uronrys. Simpson (1961) identified four
groups. two subfamilies (the Hydromyinae and
Pseudomyinac) and two other groups: one of
Rattus species and the other of Uremys/ Meln-
mys, OF these the Psecudomyinae, which in-
cludes Nortomys, Conilurus, Pseudoinys and
Leporillus species, as well as several other
genera, has radiated mainly in Australia,
whereas the other three groups are well re-
presented in New Guinea.
Several authors have recently hypothesised
phylogenetic relationships. Watts (1974) put
forward a phylogenetic scheme in which
Pyeudomys and Rattus are closely related and
Pseudomys was considered ancestral to all
Australian rodents with the exception of Melo-
inys, Mastecomys and Rattus, Mastaconrys is
shown diverging carly from the ancestral
stock, as is Rartis and Pseudoniyy. As a resull
of chromosomal analysis Baverstock ef al.
(1977b, 1977c) concluded that Rarris stood
out as a distinct group with the Hydromyinac,
and the Uromys/Melomys group diverged al
an early stage from the ancestral stock which
gave rise to the Pscudomyinac, The position of
Zyromys was considered enigmatic, but they

considered that it is probably derived from the
same ancestral stock that gave rise to the
Pseudomyinae.
Baverstock et al. (1977b) concluded that
sperm morphology might be a particularly use-
ful character in gaining further evidence about
the phylogeny of Australian rodents, as sperm
are less likely to be related to the lifestyle of
the animal than morphological characters. In
this study, therefore, we present data on
spermatozoal morphology, together with some
other aspects of the male reproductive tract
anatomy, from representatives of the main
groups of Australian native rodents.
Materials and Methods
Animals; Rodents used in the present study
were obtained from the following sources:
The hopping mice (Notomys alexis) and
plains mice (Pseudomys australis) were derived
from a laboratory stock maintained at the
Medical School, University of Adelaide (see
Breed 1975).
The water rat (Hydromys chrysogaster) was
obtained from the River Torrens near Ade-
laide; Rattus fuscipes greyi was collected near
Stirling, S.A., Pseudomys hermannsburgensis
was laboratory bred from parents collected
near Curtin Springs, N.T., and Zyzomys
argurus and Zyzomys woodwardi were col-
lected near Darwin by Dr R. Begg.
Material from the following species was
obtained from animals held at the Institute of
Medical & Veterinary Science field station in
Adelaide: Pseudomys higginsi, P. apodemoides
(see Baverstock et al. 1977a for specific ter-
minology), P. manus, Conilurus penicillatus,
Leporillus conditor, Melomys littoralis, M. cer-
vinipes, Uromys caudimaculatus, Rattus leuco-
pus leucopus, R. sordidus, R. colletti, R.
lutreolus and Notomys mitchellii (for details
of sites of capture see Baverstock et al. 1977b,
1977c, Robinson et al. 1978). Nomenclature
of Rattus spp. used is that of Robinson et al.
1978.
Preparation of spermatozoa: Spermatozoa
from 1 Hydromys chrysogaster, 4 M, littoralis,
6 N. alexis, | P. apodemoides, 4 P. australis,
1 P. hermannsburgensis, 3 R. fuscipes greyi
and 4 Z. argurus were obtained immediately
after killing the animals with chloroform. The
tail of one epididymis and adjacent vas
deferens was dissected out and sperm droplets
squeezed onto several slides. Thin smears were
made by using the edge of another slide.
Spermatozoa from the other species were ob-
tained after anaesthetising the animals with
urethane. A small incision was then made in
one scrotal sac and part of the tail of one epi-
didymis was removed from which sperm
smears were obtained as described above.
After allowing the smears to dry, they were
flooded with 2.5% glutaraldehyde in 0.01M
sodium cacodylate fixative and a_ coverslip
placed on top which was fixed in position with
De Pe X to give a semi-permanent mount. Lat-
terly wet smears were fixed with either glu-
taraldehyde or picric acid/glutaraldehyde/ for-
maldehyde mixture (sce Ito & Karnovsky
1968).
Methods of assessment of spermatozoa:
Smears were inspected by phase contrast and
spermatozoa that appeared intact, straight, and
reasonably well isolated, were selected for
measuring. Using an eyepiece micrometer the
following measurements were made: (1) head
length from the most caudal part of head to
top of the curve (see Braden 1959), (2) length
of midpiece, and (3) length of remainder of
tail (usually the principal and end pieces were
not well differentiated, so they were included
together as one measurement), Several sperma-
tozoa from each individual were observed and
usually the measurements were similar or iden-
tical, When some variation occurred the range
has been included (Table 1).
Smears were also observed by Nomarski dif-
ferential interference microscopy, and selected
spermatozoa photographed. Measurements ob-
tained by phase contrast were compared with
those made from photographs obtained by
Nomarski.
Attempts were made to determine the
presence of the acrosome and the distribution
of DNA in the sperm head from P. australis,
M. littoralis, N. alexis, Z. argurus and H.
chrysogaster. The DNA_ was determined
according to the Feulgen method (Pearse
1968) and by the use of DAPI (Russell et al.
1975). After staining by the Feulgen method
smears were observed by epifluorescence using
green excitation (Ploem 1967) (Olympus exci-
tation filter IF 545, with a G dichroic mirror
and barrier filter Y595) and by normal bright
field microscopy. When DAPI in distilled
water (about 0.001% ) was used the filter sys-
tem included ultraviolet excitation (UG 1), U
dichroic mirror, and Y455 barrier filter. Acri-
dine orange was used in an attempt to visualise
the acrosome by fluorescence microscopy (see

variation was small except for sperm from
Notomys alexis and N, mitchellii.
Sperm from all species, apart from Rattus
spp. and Notomys spp. conformed to the same
general pattern, The sperm head had a fairly
broad base which tapered to two or three
prongs or hooks. The top hook was usually
larger and invariably single, whereas the lower
one was often bifid. There was inter-specific
variation in head length (Table 1). Staining
with Feulgen and DAPI demonstrated that the
top prong consisted of DNA, and Acridine
orange indicated the presence of an acrosome
covering the nuclear material on top of the
hook and extending beyond its tip, The lower
hook(s) appeared to have DNA only at the
base and no orange or red colour was obtained
with Acridine orange.
About one-third the way up the ventral side
of the sperm head a small spike occurred to
which is attached the connecting piece. On the
dorsal side, a ridge could sometimes be seen
which stained orange with Acridine orange.
and presumably represent the continuation of
the acrosome down the dorsal side of the head.
The midpiece had very prominent gyres of
mitochondria.
Species that conform to the above general
pattern and had three hooks included Leporil-
lus conditor, Pseudomys hermannsburgensis,
P. australis, P, higginsi, P. nanus, P. apode-
moides, Conilurus penicillatus, Melomys lit-
toralis, M. cervinipes and Uromys caudimacu-
latus, These spermatozoa were similar except
that the length of the head of C. penicillatus
was shorter. Melomys littoralis and M. cer-
vinipes had smaller hooks, and only on close
examination were three discernible, Zyzomys
argurus, Z, woodwardi and Hydromys chryso-
gaster had spermatozoa of the same _ basic
structure but the hooks were not so long and
only two were visible. No bifid lower prong
could be seen. The sperm heads tended to be
shorter than most of those with the three
hooked sperm, and the breadth of the sperm
head was also less. H. chrysogaster also had a
relatively short midpiece.
The spermatozoa from Notomys alexis were
variable but consistently different. Fig. 2 shows
three different morphological types. The head
length was generally short and there was usu-
ally a short top hook and a very truncated
lower hook. Only the top hook appeared to be
surrounded by an acrosome. The midpiece of
N. alexis was generally longer than that for
other species described above (see Table 1),
but the principal/end piece appeared shorter.
N, mitchellti also had intra-individual variable
spermatozoal morphology. Sometimes there
was a single top hook which was longer than in
N. alexis and a short truncated lower hook,
whereas on other occasions, two or three
straight short hooks occurred.
The spermatozoa of all Rattus species were
markedly different from those described and
generally appeared similar to each other and
to R. norvegicus and R, rattus (Friend 1936).
The heads were long and attenuated with a
long sharp hook. Acridine orange demon-
strated the acrosome primarily on the top sur-
face of the sperm head and extending beyond
the DNA to the tip of the hook. The junction
between the mid and principal piece was not
easily visible, in contrast to the situation in
the previous species described, but when
visible it appeared that the midpiece was at
least twice as long as that for sperm from the
other groups of Australian rodents. Since the
principal and end pieces were generally similar

in lengths to those of the other groups, except
for N. alexis, the resultant total length of the
sperm was considerably greater.
Testis and male accessory organs
Analysis of gonadal weights has been per-
formed on some of the species of animals that
yielded motile sperm. Table 2 demonstrates
that testis weight/g body weight was similar in
P. australis, R. fuscipes greyi, M., littoralis and
H. chrysogaster in spite of the considerable
range of absolute body weights (60-540 g).
The relative testis weight of Z. argurus was
somewhat less and those of N. alexis and N.
mitchellii were markedly lower than in the
other species examined (Table 2).
The testes of P. australis, R. fuscipes, M.
littoralis, H. chrysogaster and Z. argurus in-
variably occurred in a scrotal sac with the tail
of the epididymis protruding into an extension
of this towards the body wall of the scrotum.
132 W. G. BREED & V. SARAFIS
By contrast, the testes of N. alexis and N. mit-
chellii appeared to usually be naturally crypt-
orchid and lay in the abdomen close to the
body wall ventral to the tail, Externally the
skin of Notomys species (and other species)
was usually pigmented and only sometimes a
slight swelling occurred. The tail of the
epididymis lay in a small cremastic sac.
The relative weights of the male accessory
organs of R. fuscipes, M. littoralis, H. chryso-
gaster, and P. australis were similar. Seminal
vesicles, together with coagulating glands
when present, ranged from 0.4 to 1.8% of
total body weight, and those for ventral pros-
tates 0.06-0.31%. The relative weights of
seminal vesicles and coagulating glands for Z.
argurus were somewhat less (0.3%-0.5%),
although that of the ventral prostate was simi-
lar. The morphology of the seminal vesicles of
Z. argurus (Fig. 3) differed somewhat from
that of the other species. N. alexis and N. mit-
chellii had seminal vesicles that were only just
visible to the naked eye. They measured about

of only two May reflect problems of technique.
The top hook was invariably made ap of DNA
over which an acrosome oecurred, whose
material stained oringe with Acridine orange.
This uppears to coincide with the hook ob-
served in many other murid redents (eg.
Friend 1936; Bishop & Walton 1960), How-
ever. the lower. usually bifid. hook appears to
be wu unique character occurring in Australian
rodents and is prestimably derived, This hook
appears to only have DNA at its base, and is
likely to be mado up mainly of acrosomal
Material, even though it does not stain orange
ov red with Acridine orange, Vartability of
staining of acrosomal material with Aridine
orange has previously been documented
(Allison & Hartree 1970), It seems likely,
therefore, that all the above genera have been
derived! from the same ancestral form in which
u Iwe or three-hooked sperm evolved.
The sperm marpholagy of Nerainys spesies
is. however, markedly different, In N. alexis
and No rdrehellii there was much indivicual

however, the sperm of N, dlevis was charac-
rerised hy a single small trulicated top hook.

ihe fotal leneth of the head and the relative
proportions of the midpiece to the rest of the
sperm til wis alse considerably different Fram
all the other genera, In Nofemivs, i contrast
ww the other species studied, there appeared to
he relutively few spermatozoa in the epididy-
mis and vas deferens, the ratio of testis
weight/total body weight was markedly less,
the testes usually appeared naturally orypl-
orchid, the seminal vesicles and coagulating
glands markedly smaller and the ventral pro-
state relatively lurger. Vaginal plugs, after
recent matings, have not vet been observed in
N. alexis, This may be due to lack of develop-
ment and seeretion of the seminal vesicles and
couxwlating glands, Other physielogical and
huhavioural significances of these differences
have yet to be elucidated. but the smaller
testes and few stored sperm suggest only in-
frequent matings would result ii suceessful
fertilizations. The sovial-sexual behaviour of
these species is Hot known in detail but it
uppears that Notamys alexiv is a highly social
animal (Stanley 1970). An anatomical feature
that may be related to this is the occurrence
of prominent chest glands (Stanley 1970,
Watts 1975), We therefore suggest hal Noto-
my has diverged further from the basic
pseadomyid stock thin siiggested on morpho-
logical characters by Tate (1951). Further
shudies or spermatozoal and male reproductive
tract morpholoxy of the other Psevdoniys anc
Netonvs species should be carried out to
determine if our findings are characteristic of
the genera. This may fot be the case as Hisen!
(1971) states thal nol all Prendomys species
have spermatozoa of similar morphology,
although she considers that only twa hooks are
normally present, She claimed that spermato-
vow al P. yhoriridvel cepresented the primitive
sperm type and fF delicatidla (as Lexaelina
delicatitla) sperm had no hooks. Unfortunately
we have not been able to reinvestigate these
findings,
The spermatozoa of Kuiras spp, were very
different from those of all other Australian
rodents and sinzilar to congeners oceurring on
ather eontinents, Ulison’ came to a siniliar
conclusion, This suggests an independent line
of evolution and invasian into Australia of

parative morphological studies of the penis,

except Rattus and the other that gave rise to
the “native” species of Rattus. More recently
Baverstock et al. (1977b, 1977c), from chro-
mosomal data, concluded similarly for the
Australian rodents. Our data on sperm mor-
phology therefore supports the phylogenetic
conclusions of these authors, but conflicts with
those of Tate (1951) who regarded the Hydro-
myinae as a separate subfamily and Simpson
(1961) who regarded the Hydromyinae and
Pseudomyinae (excluding Rattus) as separate
subfamilies.
The significance of interspecific differences
in sperm morphology has been discussed by
Friend (1936), Fawcett (1970, 1971, 1975,
1977) and others. Some mammal spermatozoa
have large acrosomes, e.g. guinea pigs (Fawcett
1970) and musk shrews (Green & Dryden
1976). The latter relate this to the thick
corona radiata around the eggs. Acrosomes of
spermatozoa of the Pseudomyinae/Hydro-
myinae/ Uromys/Melomys stock were not very
well developed, whereas those of the Rattus
spp. were similar to that of the laboratory rat.
The sperm head is very rigid, which may be
necessary for penetration of the thick zona
around the egg (Bedford & Calvin 1974),
whereas the hook of murid sperm may be
involved in motility (Cohen 1977). However,
head shape does not appear to be closely
related to species specificity for penetration of
the oocytes, as human sperm can penetrate
hamster eggs (Rudak er al. 1978). Fawcett
(1977) has suggested that the hook may deflect
the sperm from the surface of the mucosal
lining in the oviduct but as yet there appears
to be no evidence for this.
The midpiece also differs greatly between
species, Occurrence of increased mitochondrial
development of the midpiece correlates with
the evolution of internal fertilization (Afzelius
1971; Fawcett 1978), but variation in number
and shape of mitochondria between species of
mammals has not yet been given any satisfac-
tory explanation. There is no obvious correla-
tion between number of mitochondria and the
distance sperm have to swim to bring about
fertilization. Thus although there is as yet no
agreed explanation for cither sperm head
shape or midpiece length in mammalian
spermatozoa, these characters may be useful
in determining phylogenetic similarities and
differences when taken into consideration with
other morphological, biochemical, cytological
and behavioural characteristics.

BY B. D. MITCHELL
Summary
Age and growth were determined in populations of Carassius auratus from the River Murray,
Millbrook Reservoir, and a farm dam. Fish from Millbrook grew most rapidly, reaching 13.1 cm at
the end of the first year’s growth. The Uraidla population exhibited the lowest growth rate, reaching
4.7 cm at the end of the first year. Significant differences in length-weight relationships occurred
between all populations. The lenpth (1) -weight (w) equations were: Millbrook, w = 0.0297"! (7 =
0.989); Cobdogla, w = 0.0147 (c* = 0.923); Uraidla fish (< 6 cm), w = 0.0247° (7 = 0.950),
Uraidla fish (>6 cm), w = 0.0541"? (* = 0.908).

Introduction
Ecological studies of introduced freshwater
fish in Australia have concentrated on
salmonid species due to their importance in
commercial and amateur inland fisheries (Lake
1957; Weatherley 1958; Weatherley & Lake
1967; Tilzey 1970), The cyprinids, the Euro-
pean carp, Cyprinus carpio, the tench, Tinca
tinea, and the golden carp or goldfish, Caras-
sius auratus, haVe received little attention as
they have not generally been regarded of com-
mercial interest,
The history of the introduction and subse-
quent spread of European carp through south.
eastern Australia is now well documented
(Weatherley & Luke 1967; Anon, 1971; Anon.
1975; Shearer 1977; Wharton 1977). The
detrimental etlects on water quality, plants und
animals aseribed to the European carp are
manifold (Butcher 1962; Anon, 1975). Lt is
only comparatively recently, however. that
studies on the basic biology and ecology of
this species have commenced in Australia
(Lake 1966, Jones 19741; Reynolds 1976a;
Shearer 1977). Although apparently destruc-
tive in small, crowded habitats, it may not
compete with native fishes (Shearer 1977) nor
be directly responsible for the decline in
catches of most native species in the River
Murray (Weatherley & Lake 1967; Reynolds
1976b).
Weatherley & Lake (1967) have recorded
the introduction and distribution of the tench
in southeastern Australia, and this species was
fairly common in the Murray and Torrens
Rivers in South Australia (Scott, Glover, &
Southcott 1974). The tench appears to have
been displaced in the lower Murray by the
European carp (Reynolds 1976b), The food
and growth of wild populations of tench in
Tasmania bave heen studied by Weatherley
(1959, 1962), and some information is avail
able on tench growth at Narrandera (Weather-
ley & Lake 1967),
The golden carp was introduced to Vic-
torian streams about 1876 (Seott, 1953; Lake
1959) and spread to South Australia via the
River Murray (Scott 1953), This species is
widespread throughout South Australia (Scott
et al, 1974) and was “quite prolific” in streams
near Adelaide (Scott 1953), Golden carp is
also widely distributed in Queensland and
Western Australia (Weatherley & Lake 1967;
Lake 1971) and, like the other cyprinids,

appears to prefer sluggish waters (Weatherley
& Lake 1967; Scott et al. 1974).
Golden carp may be caught in “very large
numbers” in Victorian backwaters (Anon.
1971), the Albury-Wodonga area (Walker &
Hillman 1977), and in South Australia. This
species may increase water turbidity in a
fashion similar to European carp (Lake
1966). Golden carp might be expected, there-
fore, to exert similar, although less pro-
nounced, environmental effects to European
carp in those sheltered backwaters where the
latter is likely to have its most profound effect.
This paper presents information on growth
in three populations of golden carp from dif-
fering habitats in South Australia. Gut con-
tents of fish from two of these localities are
also analysed and the results discussed in rela-
tion to other cyprinids in Australia.
Methods
Three populations of golden carp from
divergent habitats were sampled using a seine
net (3 cm stretched mesh), dip nets, and a
cylindrical trap (12 cm aperture, 1,0 mm mesh
size).
Thirty-two fish were collected from a small
(100 x 40 m), shallow (0.75 m) backwater
of the River Murray at Cobdogla, S.A.
(140°24°E, 30°14°30"S) in late September
1977. The backwater was enclosed on three
sides by dense stands of cane grass (Phrag-
mites sp.), the open water underlain by soft,
fine sediments.
Thirty-eight fish were collected in March
1978 from Millbrook Reservoir, surface area
178 ha and mean depth 9,3 m, in the Mt Lofty
Ranges (138°48'45”"E, 34°49'44"S). The
reservoir has gently sloping sides, a gravel and
clay substrate, and small, localised stands of
water ribbon (Triglochin procera).
One hundred and thirty-six fish were col-
lected from a small (300 m*), deep (3-4 m)
farm dam near Uraidla, Mt Lofty Ranges
(138°30'50”E, 34°48’S) in March and April
1978. The bore-fed, clear-water dam has a
gravel and clay substrate and was bounded on
the southwestern perimeter by a narrow stand
of bullrush (Typha sp.). The entire pond bot-
tom was covered with a dense, submerged
stand of ribbon weed (Vallisneria spiralis).
Fish were treated as follows. Live weight
(gm) and = standard length (cm) were
measured. Six large, symmetrical scales were
removed from the left side of the body be-
tween the lateral line and the anterior half of
B. D. MITCHELL
the dorsal fin (after Tesch 1968). Scales were
cleaned and examined microscopically using
transmitted light. Annuli were determined
after Tesch (1968). A radius from the nucleus
to the middle-front margin of a _ non-
regenerated scale was measured using a micro-
meter eyepiece, and the distance from the
nucleus to each annulus was also measured.
The digestive tracts of 70 fish from Millbrook
and Uraidla were removed and their lengths
measured. Representative samples of material
in the intestine were taken from the fore, mid,
and hind gut. This material was examined
microscopically and analysed, using the occur-
rence and points methods (Hynes 1950), The
intestines of fish from Cobdogla had been eva-
cuated before examination.
Results
Age and Growth: The length-frequency dis-
tribution of each population sample is pre-
sented in Figure 1, It can be seen that the
length ranges of all samples overlap to some
degree. Skewness is not marked in any in-
stance, suggesting that samples were represen-
tative. The mean length and weight of each
population sample are presented in Table 1.
Mean lengths for Cobdogla and Millbrook
population samples were similar although the
length-frequency distribution indicates that fish
longer than 18 cm were more common from
Millbrook. Fish from Uraidla were markedly
shorter than from Cobdogla and Millbrook.
Mean weight was highest for the Millbrook
population sample and, as for length, lowest
for fish from Uraidla.
Log live weight has been plotted against log
standard length for each population in Figure

(n = 29, = 0.950) for fish less than 6 cm
length, and w = 0.054279 (1 = 107, r2 =
0,908) for fish longer than 6 em. No change in
the length-weight relationship was apparent
for Cobdogla or Millbrook fish, The signifi-
cance of dillerences in the exponent b was
determined by comparing the slopes of the
regression lines in Figure 2. Analysis of co-
Variance revealed significant differences (F siz,
at 0.001) in b between all populations and
between individuals shorter and longer than 6
em from Uratlla, All populations appear to be
undergoing allometric growth. ‘The change in
length-weight relationship for the Uraidla
population reflects changes in growth rate
after the formation of the first annulus.
The scales of golden carp have been de-
seribed by Llewellyn (1969) who noted that
the circuli of the embedded section were “fine
and regular”. Difficulty was experienced in the
interpretation of anauli in 12% of fish; this
was particularly the case for older fish.
Fish from Cobdogla, caught in September
1977, appeared to be in carly growing season
(a marrow band of widely Spaced circuli fol-
lowed the last annulus) suggesting that the
unnulus may have been formed in July or
August of that year, Fish aged OQ. | + and 2>
from Millbrook and Uraidla, caught in March
1978, were apparently in early to mid-growing
season, This suggested that annulus formation
and spawning had taken place later in 1977
at these localities than at Cobdogla. The mean

sive scale annuli. Scale radius is plotted against

the data best fitted a linear relationship (r-

length was, standard length = 25 (scale

tions for tench to avoid over-estimation of the

O* age group fish collected from that locality

The modified direct proportionality formula
(Tesch 1968; Chugnova 1970) was used in the

samples are presented in Table 2. Mean back-
population differences were evident. Fish from
Millbrook grew most rapidly and reached 13
cm in their first year, compared with 4.8 cm
for fish from Uraidla. Fish from Cobdogla
exhibited intermediate growth. The growth rate
of the Millbrook population was similar to that
for the fastest growing form from the Danube,
However, the Uraidla population had a !ower
growth rate than the slowest growing popula-
tion from the Danube.
Feeding: Relative gut length of fish from Mill-
brook and Uraidla was determined as length
of gut from oesophagus to anus (cm) divided
by standard length (cm). Relative gut length
varied considerably between individuals
(range = 1.64—4.48). No inter-population dif-
ferences were apparent, and no general rela-
tionship between relative gut length and body
length was discernable.

Food items found in the intestines of fish
from Millbrook and Uraidla together with per-
centage occurrence in each locality are pre-
sented in Table 3. A wide variety of organisms
were present including cladocerans, copepods,
ostracads, rotifers, caddisflies, mayflies, chiro-
nomids, molluses, green algae and diatoms.
The genera of organisms present in intestines
are all characteristically littoral in habit,
usually associated with the sediments (Brooks
1959; Edmonson 1959; Wilson & Yeatman
1959; Chapman 1967; Williarms 1968: Patrick
1977).
The mean % composition of the gut con-
tents of fish from Millbrook and Uraidla, ana-
lysed by the points method, is presented in
Figure 5. Differences in gut content between
populations were apparent, principally involv-
ing diatoms, cladoccrans and molluscs.
Discussion
Growth rate varied markedly between the
populations of golden carp sampled. The fac-
tors responsible for growth differences may be
temperature, food, or genetic variation in
growth potential. The Cobdogla population
would be expected to experience generally
higher temperatures than the Millbrook and
Uraidla populations (Bureau of Meteorology
1975). However, the Cobdogla population had
only intermediate growth. No conclusion can
be drawn from the data presented as to the
relative effects of dict on growth, Fish have
wide and variable food habits and preferences
may vary seasonally and with age (Hynes
1950; Keast 1978).

oO
The influence of genetic variation on growth
rates is usually masked by environmental fac-
tors but differences in growth do occur be-
tween forms of golden carp (Kukuradze &
Mariyash 1975) and also of European carp
(Lagler, Bardach, & Miller 1962),
Populations of golden carp in this study
exhibited lower growth rates than mainland
populations of other introduced cyprinids
(tench, European carp) in Australia (Weather-
ley & Lake 1967; Jones!). In the River Mur-
ray, S.A., European carp may reach three
times the length of golden carp from Cobdogla
in their first year of growth.
Organisms found in fish from Millbrook and
Uraidla were all characteristic of the littoral
zone and usually associated with the sedi-
ments. This, and the high proportion of detri-
tus in fish from both populations, suggests that
fish were feeding near the bottom and ingest-
ing sediments, The absence of diatoms from
Millbrook fish may be the result of poor deve-
lopment of a benthic diatom community in
that habitat or of fish feeding on benthos
below the light extinction level.
Archibald (1975) has recorded size-selective
predation by golden carp, 10-12 cm long, on
species of Daphnia and fish from the Albury-
Wodonga area appear to feed on microcrus-
tacea including true planktonic forms (Walker
& Hillman 1977). Whereas fry of this species
may feed on zooplankton, adult fish are usu-
ally more omnivorous (Lake 1966).
Tench have a “wide ranging carnivorous”
diet (Weatherley & Lake 1967) with insects
becoming more important in larger fish. How-
ever, bottom dwelling organisms occur in fish
from some _ habitats (Weatherley 1959),
Golden carp from Millbrook and Uraidla
appear to feed in a more strictly iliophagic
manner than tench. The food requirements of
the two species appear to overlap to some
extent, although the intensity of competitive
interactions will probably vary between loca-
lities.
The European carp is described generally as
a ‘bottom feeding omnivore’ (Weatherley &
Lake 1967) although diet appears to vary
widely between populations (McCrimmon
1968). Although the golden carp is capable of
increasing water turbidity (Lake 1966) it is
generally assumed not to feed in the same
manner as the European carp. The latter typi-
cally “suck up mud and other materials from
the bottom, eject it, and select food when it is
suspended in the water’ (McCrimmon 1968).
The gill rakers of this species are short, thick,
and widely spaced (Kazansky 1964) suggest-
ing that fairly large objects are dealt with
(Nikolsky 1963). The gill rakers of golden
carp are longer and more slender with lateral
processes (Iwata 1976) accounting for the
ability of this species to feed on plankton.
Golden carp may “skim off” the top layer of
the sediments, filtering out diatoms and micro-
crustacea, or simply ingesting all the material.
European and golden carp may compete more
directly than is the case for tench.
Neither European nor golden carp possess a
true stomach (Suyehiro 1942; Shuljak 1968).
The digestive tract of the golden carp appears
to be relatively longer than that of the Euro-
pean carp by a factor of two or three (Suye-
hiro 1942) suggesting that golden carp has
characteristically more indigestible material in
its diet (Nikolsky 1963; Kapoor, Smit, & Veri-
ghina 1975), However, in Australia the Euro-
pean carp has been viewed as the major detri-
tivore amongst the introduced cyprinids, This
study has shown that golden carp may be ilio-
phagic in some localities.
The precise nature of diet, gut morphology,
and mode of feeding needs to be determined
for golden and European carp in Australia.
The question of the relative effects of each
species on water turbidity, and therefore other
aquatic organisms, is important as they appear
to be most abundant in similar habitats and
may hybridize (McCrimmon 1968). The study
of wild populations of golden carp is import-
ant, both intrinsically and within the wider
context of delimiting the effects of introduced
fishes on the Australian aquatic environment.

The Mossgiel meteorite, found in southwestern New South Wales in 1967, is described
briefly. Hs chemistry and mineralogy are consistent with its classification as an LL4 chondrite,
Introduction
The Mossgiel meteorite was found in 1967
by H, Watkin during harvesting in a wheatfield
on his property “Killara”, in southwestern
New South Wales. As it had not been seen the
previous year when the crop was sown, the
meteorite may have been uncovered sub-
sequently by wind erosion, The weathered
condition of the meteorite indicates that it is
not a recent fall,
A specimen of the find was identified as a
meteorite by K, DB. Collersan, at the Mining
Museum, Sydney. Collerson subsequently
acquired it, then in 23 pieces, He named it
Mossgicl as it had been found southeast of that
town (approximate site of find: 33°19'S,
144°47°E), Collerson registered the meteorite
with the International Meteoritical Commission
in 1969, The bulk of the meteorite is now in
Canada where it was taken by him in 1972.
The meteorite was originally described as an
olivine bronzite chondrite (Krinov 1970).
However, results obtained by Mason [1974)
and Fitzgerald (19792) suggest a different
classification, Here | present a brief description
of the meteorite, bulk and mineralogical com-
positional data and discuss its classification.
Experimental methods
X-ray fluorescence analysis was used for the
determination of all elements exeept sodium
for which a flame photometric method was
employed, A modified yersion of the Norrish
& Hutton (1969) technique for X.R.P. analysis
was used, Olivine determinations were carried
out using the method of Yoder & Suahama
(1957) which involves measurement of dis
spacings using zine oxide as an internal stan-
dard, Details of methods are in Fitzgerald
(1979a).
Description of the meteorite
A small fragment of the meteorite was
examined, Isolated grains of metal and
tarnished sulfides are disseminated throughout
the silicates which are stained brown from
oxidative alteration. In places these iron-rich
opaque minerals have been completely replaced
with limonite and other oxides. Chondrules
are Visible on a cut surface, many being partly
or wholly surrounded by troilite rims; they can
also be seen penetrating through the fusion
crust,
The major minerals present in the meteorite
are olivine, pyroxene and metallic nickel-iron,
Minor amounts of troilite and other minerals
are present. The composition of the olivine as
determined by X-ray diffraction, Fass“, com-
pares well with the value of Fags: reported for
this meteorite by Mason (1974) using an
electron microprobe. The tendency to lower
iron content in the diffraction results matches
the trend observed for other meteorites by
Mason (1974) and Fitzgerald (1979a).
In thin section the meteorite has a fragmen-
tal appearanee, most of the silicates being
heavily stained with limonite and other iron
oxides. Chondrules are present in addition to
lithic fragments and monominerallic grains.
Many of the lithic clasts are fragments of
porphyritic material containing clasts of skeletal
olivine and polysynthetically twinned clino-
pyroxene. The latter commonly poikilitically
encloses sub-rounded to rounded chadacrysts

of olivine or orthopyroxene. A significant num-
ber of poikilitic orthopyroxene grains are
present also. In many cases the brecciated
nature of the meteorite is partially obscured
by an integration of clast margins, possibly
produced by recrystallization. Many of the
chrondrules are fractured, and now have veins
of opaque minerals running between the frag-
ments. Much of the glassy mesostasis in the
porphyritic inclusions has been devitrified to
fine grained pyroxenes, while in some cases,
some clasts appear to have been completely
devitrified and recrystallized. Evidence of
shock, in the form of undulose extinction, can
be seen in many of the larger pyroxene grains
and in many instances a mosaic texture is
present. In contrast, most of the olivine grains
are characterized by sharp extinctions.
Bulk chemical composition
The bulk composition is listed in Table 1
along with the results of a normative calcula-
tion. The assumptions made in this modified
form of the CIPW calculation are documented
fully by Fitzgerald (1979a), Phosphorous has
been assigned to the mineral species merrillite
(B-Cas(PO1)2) as this has been shown by
Dowty (1977) to be the principal meteoritic
phosphate.
Classification
Values of the atomic ratios (expressed on a
percentage basis) Ca/Mg (4.5), Fe/(Fe +
Mg) (34), Al/Si (7.0) and Ca/Si (4.3) all
fall within the ranges used by Fitzgerald
(1979a) to define the ordinary chondrites.
Both the absolute iron content (18.4%) and
the low value of 49 for the Fe/Si ratio are
suggestive of an LL chondrite classification
whereas the olivine composition of approxi-
mately Fas is appropriate to the L group.
Mossgiel belongs to petrologic type 4 (Mason
1974) and so it is possible that it contains
unequilibrated silicates. Electron microprobe
determinations were not carried out on this
meteorite and so this point could not be con-
firmed. Dodd et al. (1967) found that in the
L and LL chondrites the average iron con-
tent of the olivine increases during equilibra-
tion. As a result, unequilibrated members of
these groups can have olivine compositions
appropriate to the H or L groups, but bulk
chemistries characteristic of either the L or LL
group. (It is also possible that the fairly
extensive weathering, seen in thin section, has
resulted in an iron-loss, with the result that the
olivine composition accurately indicates the
correct classification. )
Mason & Wiik (1964) suggested that the LL
chondrites are frequently characterized by a
scarcity of chondrules and a_ prominent
brecciation. The texture of Mossgiel does not
completely accord with this description, but
since nine of the 12 meteorites examined by
these authors belonged to the LL6 group, the
lack of chondrules probably only reflects
recrystallization effects, and is not necessarily
typical of the LL group as a whole. Fodor &
Keil (1975) also pointed out that the LL
(HE MOSSCGIEI
chondrites are characterized by their breccia-
ted structure and described poikilitic lithic
fragments from five LL chrondites. In general,
they found olivine chadacrysts poikilitically
enclosed in orthopyroxene oikocrysts.
Comparison of Mossigiel with a section of
the LLS5 chondrite Forrest Lakes, figured by
McCall & De Laeter (1965), shows some
points of similarity. Lake Labyrinth, an LL6
chondrite, has been more extensively recrystal-
lized than either Mossgiel or Forrest Lakes,
with the result that very few chondules can
he seen, This recrystallization has not, how-
ever, destroyed the poikilitic nature of the
large orthopyroxene grains which enclose
chadacrysts of olivine. Both Forrest Lakes and
Lake Labyrinth were found in the Nullarbor
Plain, Forrest Lakes just west of the state
border and Lake Labyrinth northwest of
Kingoonya, The fall of the latter (recovered
in 1934) was probably witnessed in 1924, A
complete analysis of this meteorite has not
heen published previously. Accordingly, an
analysis obtained using the same analytical
METEORITE 147
technique is included in Table J, as is one of
Obcron Bay, another LL chondrite examined
in this work, This latter meteorite, which was
recovered on Wilson’s Promontory, has some
unusual features and is deseribed in full by
Fitzgerald (1979b). Table 1 also meludes
analytical results. for the LL3 chondrite Ngawl.
Much of these duta were obtained by Ahrens
etal, (1969) using a similar X.R.F, method of
analysis. In order to present a complete
analysis, these results were supplemented hy
those of Mason & Wiik (1966),
On the basis of textural relationships and
its bulk chemistry Mossgiel is classified as an
LL4 chondrite. The apparently olivine com-
position may be the result of lack of equili-
brium in the major silicate minerals,

Plateau, Western Australia. Trans. KR, Noe, 8. Aust. 10306), 149-153, 31 August, 1979.
A new species of Literia is described. t| is of moderute size (males 44-51 mm, females
50-57 mim S-V), and is a further representative of the L, caerulea group. Amongst its osteo-
logical features it is unique in Litaria in exhibiling a supraorbital sphenethmoid flange.
Introduction
For over a century Literia caerulea (Shaw)
was considered a highly distinctive hylid frog,
and in fact Gunther (1858) erected the genus
Pelodryay and family Pelodryadidac to accom-
modate it. The species was first reported from
South Australia by Tyler (1977). Tyler et al.
(1977) described the new species Litoria
yplendida which they considered derived from
it, and Tyler and Davies (1978) associated the
two species within a species group.
This paper deseribes a further new species
of the L, caerulea species group.

Hind limbs rather short (TL/S-V 0.48).
Toes in decreasing order of length 4 > 5 > 3
> 2 > 1. Webbing on toe 5 reaches slightly
above subarticular tubercle at base of penulti-
mate phalanx; extends to subarticular tubercle
at base of penultimate phalanx of toe 4 and
continues to discs in form of broad lateral
fringe. Subarticular tubercles prominent. Large
oval inner and small rounded outer metatarsal
tubercles (Fig. 2).
Dorsum coarsely granular; skin fold along
posterior edge of forearm and slight tarsal fold,
Supratympanic fold narrow. Ventral surface
coarsely granular.
In preservative the dorsum is a uniform pale
brown and the ventral surface uniform pale
cream.
This male specimen has unpigmented nuptial
pads, and a submandibular vocal sac with
short apertures near the articulation of the
jaws.
Dimensions of holotype
Snout to vent length 48.0 mm; head length
16.7 mm; head width 18.2 mm; tibia length
23.0 mm; eye to naris distance 4.8 mm; inter-
narial span 4.0 mm; eye diameter 5.3 mm;
tympanum diameter 4,2 mm.
Variation
There are 14 paratypes: WAM R43329-30
collected with the holotype by L. A. Smith
and R. E. Johnstone; WAM R60680-84 collec-
ted at East Mitchell Falls, by W. H. Butler on
4.11.78: WAM R61624-30 sandstone upon
Mitchell Plateau, W. H. Butler 20-28.2.79. Five
of the paratypes are adult males (44-50 mm
S-V) and two are females (50 and 57 mm
S-V respectively). The larger of the females
is gravid; the smaller has few ova but convolu-
ted oviducts and may have deposited ova
shortly before capture.
The overall proportions of the paratypes are
similar (HL/HW _ 0,.89-1.05; HL/S-V_ 0.32-
0.37; E-N/IN 1.13-1.38). The tympanum is
clearly defined and a distinctive feature in all
representatives. Webbing shows no detectable
variation, The skin is coarsely granular in the
series collected at Surveyors Pool, but less
conspicuously granular in the series from the
East Mitchell Falls.
Osteology (based on WAM R60681—Fig. 3)
Skull moderately well ossified, broader than
long; sphenethmoid well ossified projecting
between nasals almost to anterior extremities.
Ventrally ossified portion of sphenethmoid

Comment; The presence of a supraorbital
sphenethmoid flange has not been reported
previously in the Hylidae, Supraorbital fronto-
parietal flanges are not uncommon, but the
anterior progression of the flange is unusual.
Comparison with other species
The overall habitus of L. cavernicola, size
of digital discs, presence of interdigital webbing
and colour in life are all reminiscent of L.
caerulea, and the relationship with that species
appears closer than with any other congener.
Accordingly it has been compared with
individuals of caerulea from various parts of
that species’ range and a detailed morphometric
comparison made with a series of 13 L. caeru-
lea taken upon the Mitchell Plateau: KU
180663-64, SAM RI17147-R17155. Table 1
demonstrates that L. cavernicola is significantly
smaller, has more narrowly spaced nostrils (so
producing a higher E-N/IN ratio), lacks the
short head of L. caerulea (HL/S-V 0,32-0.37,
compared with 0.29-0.32 in L. caerulea).
Litoria cavernicola has longer legs; only one
specimen having a TL/S-V ratio below the
maximum for L. caerulea.
Litoria cavernicola lacks the large parotoid
glands of L. caerulea, which in that species
obscure the upper and posterior margins of the
tympanum. Thus in L, cavernicola the tym-
panic annulus is entirely visible.
Features of the skull of Z. cavernicola have
much in common with L. caerulea. However
some quite considerable differences have been
observed as follows: nasals of L. cavernicola
are more slender than those of L. caerulea
whilst the sphenethmoid is more ossified in the
former species. A supraorbital sphenethmoid
flange is present in L. cavernicola compared
with a small supraorbital frontoparietal flange
in L, caerulea, The zygomatic ramus of the
squamosal is shorter and otic ramus longer in
L. cavernicola than L. caerulea. The preorbital
process of the pars facialis is in bony contact
M. J. TYLER & M. DAVIES
with the maxillary process of the nasal in L.
caerulea but not in L. cavernicola, The alary
processes of the premaxillaries are perpendi-
cular in L, cavernicola and curved posteriorly
in L, caerulea. The anterior alae of the pre-
vomers are reduced in L. cavernicola but not in
L. caerulea. The cultriform process of the
parasphenoid is irregularly truncate in L.
cavernicola but acuminate in L. caerulea whilst
the alae are at right angles to the cultriform
process in L. cavernicola but directed slightly
posterolaterally in L. caerulea.
Relative widths of the transverse process of
the presacral vertebrae differ, being HI — SD
> IV >VU> I= Vil = VUl > Vin LZ.
cavernicola and II = SD > IV > V = VI
= VII = VUI > IL in L. caerulea.
Litoria splendida is a further representative
of the L. caerula species group as defined by
Tyler and Davies (1978). It is a large species
(up to 100 mm S-V) and is distinguished from
L. cavernicola by possession of vast, hyper-
trophied, supracranial glands and conspicuous
pale yellow spots upon the green dorsum,
Habitat
Litoria cavernicola has been collected only
from large caves in sandstone gorges. Else-
where in the Kimberleys such caves are in-
habited by L. caerulea and L. splendida.
Distribution
Only known from the gorges bordering the
Mitchell Plateau, W.A., but possibly wide-
spread in comparable gorges in the inacces-
sible country (subhumid northwest Kimberley).
Etymology
The specific name is derived from the Latin
caverna (a hollow; cave or cavern) and cola
(inhabitant).

BY P. DE DECKKER
Summary
Ngarawa dirga n.gen., n.sp. of the new subfamily Ngarawinae, is described from mound springs and
spring seeps in the Strangways-Curdimurka area, southwest of Lake Eyre South. Two other
cyprididid ostracods are recorded from temporary pools in the same area: Reticypris walbu n. sp.
and Heterocypris tatei (Brady, 1886). The latter species is redescribed and recorded from some
mound springs.

Introduction
Natural artesian springs commonly occur
along the edge of the Great Artesian Basin
and some are in the area between Strangways
and Curdimurka, South Australia. Some of
these consist of dome-shaped structures or
“mounds” (Fig. 1) from which water flows
slowly. Inside the open domes, small pools
often occur which overflow through a “seep”
(Fig. 2), The waters from these springs are
commonly slightly saline and alkaline having
conductivities of up to 9000 millimhos/cm.
Spring water temperatures are usually high
(e.g. 18-30° in early October 1978), those of
the seeps characteristically higher than the
pools. As the mound springs are the only
—
Mound at Horse Springs. Note the
characteristic cone shape of the spring.
The sides of the spring are made of
calcareous encrustations leached by the
spring waters. Distance across the top of
the spring is approximately 20 m. (Photo
B. D. Mitchell).

prominent water bodies in an arid area, they
might be expected to provide unique habitats
for an endemic fauna, as is the case for the
remarkable phreatoicid isopod Phreatomerus
latipes (Chilton, 1922), As yet undescribed
gastropods collected from the same mound
springs are also endemic (B. V. Smith in litt.
to B. D. Mitchell, 24.xi.1978). One new
ostracod genus and new species is a common
inhabitant of the mound springs and _ their
seeps, and believed to be endemic to the area.
For further details of the area, refer to Cobb
(1975) and Mitchell (in press).
The material analysed here was collected by
B, D. Mitchell during the period of 30.ix.-3.x,
1978 during an investigation of the mound
springs by the Nature Conservation Society of
South Australia. Some collections made by
K. F. Walker in the same area were also
examined, i
The specimens used for the description of the
three ostracod species are deposited at the
Australian Museum (AM _ P28669-P28692).
Paratype material is also deposited at the
South Australian Museum, British Museum
(Natural History) and U.S. National Museum.
Aboriginal words are used here to name the
new ostracods because the area where they
were collected is rich in myths of the Arabunna
people.

Order: PODOCOPIDA Miiller, 1894
Superfamily: CYPRIDACEA Baird, 1845
Family: CYPRIDIDAE Baird, 1845
Subfamily: NGARAWINAE new subfam.
Type genus: Ngarawa dirga n. gen., n. sp.
Diagnosis: Carapace: left valve with dorsal
hump and slightly larger than right valve; edge
of right valve with faint tuberculation pos-
teriorly; broad selvage near edge of left valve
but forming edge of right valve; calcified inner
lamella broad anteriorly; central muscle scars
consisting of 6 scars at the maximum arranged
in circle; 2 on top with one or 2 below in
centre, and 2 others below; 2 mandibular scars
below and in front; radial pore canals
numerous, straight and arranged in groups of
2 and sometimes bifid; 4 rows of seminal
vesicles forming U-shape in posteroventral area
and forming 2 loops, one clockwise in dorsal
area around central muscle field, the other
anticlockwise in posterodorsal area.
Anatomy: antennula 7 segmented with one
thick and straight bristle at the end of last
segment; antenna with small unequal natatory
setae; mandibular endopod with « bristle long,
narrow and with pilose distal end, 8 bristle
with smal! and fine short hairs and 7 bristle
very long and with pilose tip; rake-like organ
with 6 teeth; last segment of maxillular palp
trapezoid; the 2 Zahnborsten on 3rd lobe of
maxillula with teeth; male maxillary palps
almost identical with 2 long and narrow bristles
plus 6 pilose bristles on epipod; Zenker organ
with both ends rounded and bearing 25
rosettes; furca with 2 long claws almost equal
in length and 2 bristles; furcal attachment with
one ventral extension near articular extremity,
2 small dorsal branches and a bifid ventral
one; no spine on posterior of body.
Remarks: This new subfamily is at present
monospecific. The Ngarawinae resembles the
Cyprinotinae in dorsal hump in left valve
and tuberculate edge of one valve, but differs
from it by possessing a trapezoid end segment
of maxillular palp, almost identical maxillar
palps in males, different shaped hemipenis (in
Cyprinotinae it usually has a boot shaped
lateral lobe) and furcal attachment with 2
dorsal branches and a ventral process near
articulary extremity.
The furcal attachment, which was shown by
Rome (1969) to be an important feature for
distinguishing various subfamilies within the
Cypridacea, separates Ngarawa from Priono-
cypris Brady & Norman, 1896, redescribed by

Danielopol & McKenzie (1977), which, other-
wise resembles the former genus in many
anatomical details. However, the similarity of
the furcal attachment of Ngarawa with those
of the genera included with the Herpeto-
cypridinae still does not necessitate the associa-
tion of this genus with Herpetocypris, Ilyodro-
mus and Psychrodromus because the furca,
another distinguishing taxonomic feature at the
subfamily level, has different types of bristles.
Therefore the Ngarawinae could be a transi-
tion form between the Herpetocypridinae and
the Cyprinotinae. Whether or not it is ancestral
to these families is not yet known.
Ngarawa n. gen.
Type species: Ngarawa dirga n. sp., gender
feminine.
Diagnosis: Same as for subfamily Ngarawinae.
Derivation of name; From guda ngarawa in
Arabunna vocabulary meaning mound spring,

Ecology: Ngarawa dirga is a benthic ostracod
found in most springs in the Strangways-
Curdimurka area. B. D. Mitchell collected
specimens of this species from the following:
Hamilton Hill Homestead Spring (T. 18°C,
cond. 8970 mmho); unnamed spring near
Blanche Cup; Blanche Cup (T. 14°C, cond.
6952 mmho); The Bubbler (T. 30°C, cond.
5943 mmho); Coward Spring Railway Bore—
swamp; Coward Springs (T. 28°C, cond, 6811
mmho); Warburton Spring; Strangways Spring.
N. dirga was also collected from 2 mound
springs seeps: Horse Springs Seep (T. 23°C.
cond. 7047 mmho) and Blanche Cup seep
(T. 28°C). K. F. Walker collected N. dirga
on 30.xi.1975 from the Blanche Cup Spring
(T. 29°C), the Bubbler (T. 31°C) and the
Little Bubbler (T. 28.5°) near the latter
spring. For all these localities refer to the
1:250 000 Curdimurka topographic map.
Mitchell noticed that in the seeps, N. dirga
was crawling on a rocky bottom covered with
algae and also within sandy sediment, The
water depth in places was a few millimetres.
N. dirga was not found swimming, a fact
explained by the undeveloped natatory setae
on its antennae and the presence of a thick
bristle attached to the last antennular segments
which would be useful for crawling. It is likely
that the abundant hairs covering the carapace
of N. dirga are of some use in keeping the
animal moist by trapping a water film or
bubbles around the shell, and in maintaining
the animal's vertical position by the hairs acting
as lateral stabilizers when water is depleted
within the seeps. Abundant hairs are also

Reticypris walbu n. sp.
Figs. 35-63.
Holotype: Adult male, AM P28688,
Paratype: Ovigerous female, AM P28689.
Type locality: Pool in Margaret River, S.A.
(lat. 29° 22’ 38” S; long. 136° 46° 52” EB).
Derivation of name: Walbu in Arabunna
terminology meaning rib bone for the saw-like
appearance of the dorsal edge of the shell.
Walbu relates to the particular myth at the
Blanche Cup and Bubbler Springs when a
mythological hero captured and cooked in a
spring a large snake, discarding the rib bones
to form the white encrustations seen at the
edge of the spring.
Diagnosis: Saw tooth like ornamentation in
the dorsal area of the shell, and posterior edge
of both valves with broad denticulation, Shape
of hemipenis as in Fig. 60.
Description: Carapace. (External). Holotype
adult male: length LV 0.725 mm, RV 0.71
mm; height LV 0.485 mm, RV 0.48 mm.
Paratype ovigerous female: length LV 0.82
mm, RV 0.81 mm; height LV 0,54 mm, RV
0.53 mm. Carapace kidney shaped with curved
dorsum; ventrum deeply incurved; hexagonal
reticulation all over carapace; broad denticula-
tion along posterior edge, and sometimes
anterior edge, of valves—this denticulation
occurs on a rim that contours both valves all
around near flange and continuing in dorsal
area where denticulation has appearance of
saw (Fig. 48)—greatest height at about 1/3
from anterior, and greatest width at about 2/3
from anterior. LV longer especially in anterior
area; overlap of LV over RV dorsally with
stronger overlap at 1/3 from anterior (Figs
43-44). Reticulation of valves and denticula-
tion along edge of valves present in juveniles
(Fig. 46).
(Internal). Selvage narrow anteriorly and
broad posteriorly in both valves; calcified inner
lamella at least twice broader than outer
lamella anteriorly, whereas nearly absent pos-
teriorly. Hinge: fine groove in RV (Fig. 48)
and ridge in LV; in LV, anterodorsally and
posterodorsally small extension, for over-
lapping RV, covering the fine ridge. Central
muscle field with inclined row of 3 broad
horizontal scars and one behind middle one
and a small one in front of top one; 2 mandi-
bular scars below and in front. Radial pore
canals numerous and straight. In male 4 rows
of seminal vesicles parallel to dorsum and
curved anteriorly and posteriorly to form
complete tight loop at least posteriorly (Figs
39-40).
Anatomy. Antennula: (Fig. 49); 7 segmen-
ted; length/width ratio of last 6 segments:
5 ee g, 32, +. 33, natatory setae
almost as long as last 6 segments. No sensory
organ seen on 2nd segment.

Rake-like organ: (Fig. 59); 10 (in male)
and 11 (in female) and narrow teeth with
interior one bifid.
Maxillula: (Fig. 52); length/width ratio
of palp segments: we — end of palp with
2 smooth and thick bristles; 2 long setae
attached to middle of Ist lobe on posterior
side.
Maxilla: sexually dimorphic; in male (Figs
56-57) palps asymmetrical and bearing 2 small
pointed setae at base of clasping palp; in
female (Fig. 55) 3 pilose setae, each of
different lengths, the longest one twice the
length of small one.

undivided; claw as long as last 4 segments;
for details of setae see Fig. 54.
Thoracopoda [I: 2 terminal setae with
longest one 3 times length of hook-shaped

and internal one strongly chitinized, brown in
colour and cudgel in shape; for outline see
Fig. 60.
Zenker organ: (Fig. 63); both ends slightly
funnel-shaped and with 16 rosettes.
Furca: sexually dimorphic; 2 strong pec-
tinate claws: anterior one nearly twice length
of posterior; in male (Fig. 61) anterior bristle
twice length of posterior and longer than
posterior claw; in female (Fig. 62) both
bristles of equal length and smaller than pos-
terior claw.
Furcal attachment: (Fig. 58); long and
strongly arched dorsally with one small dorsal
branch curved away from articular extremity
near which a small spike occurs ventrally.
Eye: cups of nauplius eye fused.
Colour of shell: (preserved in alcohol)
females dark green; male light green.
Remarks: Reticypris walbu differs from R.
herbsti McKenzie, 1978 and R. dedeckkeri
McKenzie, 1978 on the following grounds: the
shell is reticulated entirely and is broadly
denticulated all around the edge of valves
(forming a saw tooth-like feature dorsally)
whereas in the latter two species the shell is
almost smooth anteriorly and posteriorly and
bears very fine denticulations along the margin
of the shell except in the dorsal area, The
hemipenis outline also differs: see Fig. 60 and
McKenzie (1978, p. 186, Figs 71, 76). The
spike near the articulary extremity of the
furcal attachment was not described by
McKenzie for Reticypris but it was found on
topotypic R. herbsti. This feature may be
diagnostic of the Diacypridinae.
Ecology: All Reticypris species are restricted
to saline waterbodies and therefore it was not
surprising to find R. walbu in the pool in
Margaret River which Mitchell described as
saline to taste. W. Zeidler collected this species
at Davenport Spring on 2.xii.1974.

here for H. tatei because Brady (1886) only
described the carapace, and this was done
insufficiently and incorrectly.

and longer in left one where it is almost as
long as posterior one. Claws unequal: posterior
one 2/3 length of anterior.
Furcal attachment: (Fig. 95); slightly
curved with dorsal branch very thin and curved
away from articular extremity.
Eye: cups of nauplius eye fused; dark brown
in colour.
Colour of shell: transparent to white when
in alcohol.
Distribution and ecology: The original locality
was given by Brady (1886) as “brackish pools
in a dry creek at Adelaide”. However, the
holotype slide was labelled “Brackish Pools,
Dry Creek, Adelaide”, A river named “Dry
Creek” exists in the north of Adelaide and it
is thought to be the locality from which
Professor R. Tate collected the specimens
described by Brady. Part of Dry Creek has
been transformed into a drain. Heterocypris
tatei has been collected by B. D. Mitchell at a
temporary pool near Hamilton Hill Homestead,
at Coward Springs Railway Bore Swamp and
Coward Springs. One emptied carapace. was
collected by K. F. Walker from Dalhousie
Homestead Spring on 4.x.1975. This species
has also been collected by J. Arnold on 9.vi.
1977 in a pool at Beringboding Rock, W.A.
(lat. 30° 34’ S; long. 118° 29’ BE).
This ostracod, as for most species recorded
in the genus, is a common inhabitant of tem-
porary pools. It is not surprising therefore to
find it in the various pools and swamps in the
area studied as well as in one of the springs
(Coward Springs) where the conductivity was
6811 mmho. Inhabitants of temporary pools
can usually withstand slight salinities but are
never found in saline lakes.
Remarks: Outside Australia, the average length
for Heterocypris species is about 1 mm. H.
tatei and H. leana (Sars 1896) are exceptions.
The length of the adult female of the latter
species is 2.70 mm and the size of some
Heterocypris spp. can vary greatly: Hetero-
cypris aurea (Sars 1896) described from South
Africa had a length of 1.32 mm (male) and
1.60 mm (female) but Daday (1913) recorded
for it a length of 2.2 mm (male) and 2.5 mm
(female), (McKenzie 1971). The holotype of
H. tatei is slightly smaller than the specimens
described here but the length/height ratio is
very similar for Brady’s specimens and for
those from the Mound Springs area.
It is important to point out the difference in
sizes of specimens within a species because
many Heterocypris species have been dis-
tinguished only on the basis of the length and
height of the carapace.

futroduction
About one-third of the known frog fauna
of the Australian continent has been described
in the last decade (Tyler 1979a), Many of
these descriptions arise from the re-examination
of existing material, but a large proportion of
hew specics has resulted from greater access
to remote areas, and the intense activity
generated by faunal surveys,
The faunal survey program of the Queens-
land National Parks and Wildlife Service has
resulted already in the description of Literia
longirasiris (Tyler & Davies 1977) and
Caphixalus concinnus (Tyler 1979b). A
further undescribed species was collected by
J. W. Winter and R. G, Atherton af Alex-
andra Creek, neur Thornton Peak in 1976.
The species appears to be a member of the
Litoria nannotis species group as defined by
Liem (1974) and Tyler & Davies (1978),
Here we describe the new species and
compare it with other members of the L,
naunots species group.
Materials and methods
‘Lhe specimens reported here ure deposited
in institutions whbreviated in the text as
follows! American Museum of Natural History
(AMNH), British Museum of Natural History
(BMNH), Queensland Museum (QM),
Queensland National Parks and Wildlite
Service (OP), South Australian Museum

tions follow ‘Trucb (1979). Cleared and
stained material was prepared by a. slight
modification ef the method of Davis & Gore
(1947) whilst dried skeletal preparations
were made following the methods cited by

calary structures cartilaginous,
Comparison with other species
(a) External morphology: The medium size,
slight finger webbing, extensive toe webbing,
dull colouration, spiny nuptial pad, lack of
vocal sac and large unpigmented ova are a
combination of features exhibited by members
of the Litoria nannotis species group viz.
L. nannotis, L. nyakalensis and L. rheocola. L.
lorica is undoubtedly a member of this species
group.
The species can be distinguished from L.
nyakalensis and L. rheocola by the presence
of accessory pectoral spines in the male, the
indistinct tympanum and the enlarged prepollex
(Fig. 2). It can be distinguished from L.
nannotis (the species to which it seems to be
most closely related) by its smaller size (L.
nannotis male S—V 40.1—53,.2 mm, female S-V
46,3-56.0 mm), its truncate snout (Fig. 6)
and the terminal position of the nares. In
addition, L. nannotis males have more ac-
cessory spines in the head region, and on the
forearm and thighs, and have a more robust
forearm than L, lorica,

skull of L. nyakalensis, NP N14284.
(b) Osteology: The skulls of L. nannotis, L.
nyakalensis and L. rheocola are illustrated in
Fig. 4. Litoria lorica can be distinguished from
L. nannotis by reduced ossification of the
neurocranium, the anterodorsally projecting
alary processes of the premaxillaries (account-
ing for the more truncated snout shape in
L. lorica), the lack of a pronounced preorbital
process on the pars facialis of the maxillary,
larger exposure of the frontoparietal foramen,
the stockier crista parotica, the longer den-
tigerous processes of the prevomers and the
very slender medial extremities of the palatines.
Postcranially, £. nannotis differs from L.
lorica in having poorly expanded sacral
diapophyses and the relative width of the

transverse processes of the presacral vertebrae
of WI > Sacrum > IV > II > V = VI =
VIL = VII.
The bony prepollex of L. nannotis is larger
than in L. lorica and a number of flanges are
present on the adjacent metacarpal compared
with the single flange in L. lorica. Presence of
humeral flanges dorsally and ventrally in L.
nannotis (Fig. 5) is similar to the condition
in L. lorica although these are more pro-
nounced in the former species.
L. lorica differs from L. rheocola in having
reduced ossification of the neurocranium, no
contact between sphenethmoid and nasals, an
elongate frontoparietal foramen, a complete
quadratojugal, longer dentigerous processes of
the prevomers and slender medial extremities
of the palatines.
Postcranially, medial separation of the
coracoids is less in L. lorica than in L.
rheocola, Humeral flanges are poorly de-
veloped in L. rheocola (Fig. 5) and there is
no flange on the adjacent metacarpal to the
narrower bony prepollex. Relative widths of
the transverse processes of the presacral ver-
tebrae in L. rheocola are Il > Sacrum =
IV > Il > V = VI = VII = VIII. The
intercalary structures are ossified.
L. lorica can be distinguished from L. nya-
kalensis by reduced ossification of the neuro-
cranium, absence of nasal contact with the
sphenethmoid, an elongate frontoparietal fora-
men, longer dentigerous processes of the pre-
vomers and slender medial termination of the
palatines.
Postcranially, L. lorica and L. nyakalensis
are similar with comparably developed hu-
meral and metacarpal flanges and prepollices.
The relative widths of the transverse processes
of the presacral vertebrae in L. nyakalensis are
Ill > Sacrum > I] > IV > V = VI= VIL =
VII. Intercalary structures are bony.
Larval morphology: The tadpole is unknown
but the habitat preference of the adult indi-
cates that it is probably a torrent-adapted form.
Habitat: The type series was collected on
granite boulders in notophyll vine forest in the
splash zone near turbulent, fast-flowing water.
At the type locality L. lorica is sympatric with
L. nannotis, L. rheocola and L. nyakalensis.
L. nannotis is usually found in the splash
zone of rapids and waterfalls, but. some speci-
mens of both sexes have been collected on
trees away from these areas. L. nyakalensis is
usually found on branches overhanging
streams, rarely on rocks, whilst L. rheocola is
found on rocks and sometimes on overhang-
ing branches near broken water.
Differing habitat preferences are exhibited
by each of the four species although L. nan-
notis and L. lorica seem to exhibit the least
separation. Further data should clarify this
situation.
Distribution: L. lorica has been collected only
at the type locality of Alexandra Creek near
Thornton Peak.
The Litoria nannotis species group
Liem (1974) discussed the three species of
the L, nannotis group then known. With the
description of L. lorica and further data now
available to us on the other members of the
group, some additions to Liem’s descriptions
are necessary.
On a number of morphological and osteo-
logical criteria the group falls naturally into
two species pairs: L. nannotis and L. lorica,
and L, rheocola and L. nyakalensis; these fea-

tures include expansion of the dises (Fig, 2
secondary sexual characters, condition of the
quadratojugal (Fig. 4) and intercalary struc-
tures. Whilst there is little difficulty in separat-
ing members of the former pair from each
other and from the other pair, and the males
of the second pair from cach other, preserved
fernules and non-breeding males of L. rheacola
und £, nyakelensiy are difficult to distinguish
on external morphology alone,
A great deal of intraspecific variation occurs
in many characters. Ror example, live speci-
mens of L, nvakalensis are usually, but not
always, pinkish on the Ventral surface, and this
colouration invariably disappears in preserva-
tive, Head shape varies slightly with the
group (Fig. &) but state of preservation can
distort this character. Hand and foot webbing
show slight differences between the species, but
again intraspecific variation occurs. The tym-
panum is generally indistinct or not visible
externally in L. lorica andl. ninnotis, whereas
in L, rheacela and L. nyakalensis it is wsually
distinct.
Vocal sacs are absent in all members of the
species group, but males of L. rheecola and L,
nyakalensis are capable of depressing the sub-
mandibular region during vocalization (M,. J,
Tyler, pers, comm.,).

The one morphometric measurement that
Liem used to distinguish members of the group
—the relationship between eye to maris dis-
tance and ipternarial span was found to be in-
consistent in the series of frogs examined by us
(L, nannotis E-N/IN 0,84-1.24, L, rheocola
0.86-1.15, L. nyvekalensis 0.88-1,35), How-
ever, we find that the head length to head
width ratio separates L, rheocola from L, nye-
kaletists.
Osteological comparisons are between males
because females of L. nyekalensixs Have not
been available to us for study. Many of the
osteological features separating L. rheocola
and L. nyekalensiy (such as development of
humeral crests and metacarpal flanges, asso-
ciated with the development of the forearm
and prepollex) may be sexually dimorphic.

Jntroduction
Most of the nematudes recorded here
were taken trom birds dissected by the author;
others were donated by other collectors, Some
Tetrameridae from Australian birds have al-
ready been described, and those dealt with
here are additional ones (Johnston & Mawson
1941, 1949, 1951; Mawson 1968, 1977).
Chabaud (1975) divides the Tetranieridae
into subfamilies, and places Microhadjelia
Jogis and Tetrameres Creplin in the Telra-
merinae, Microtetrameres he considers a sub-
genus of Tetrameres, on the grounds that the
head structures of the two groups are similar
though not sufficiently studied, In practice
however they are readily separable, the females
by the body shape, and the males usually by
the type and arrangement of the caudal pa-
pillae, though this latter is noted more casily
in the actual specimen than in line drawings.
Microtetrameres is retained as a genus here,
Chabaud also refers to the unsatisfactory
definitions for the subgenera usually attributed
to these genera, In the case of Tetrameres, the
three subgenera have in the past been sepa-
rated by the absence of body spines (Gynae-
vophila) and by the presence (Petrowimeres)
or absence (Tefrumeres) of lateral cuticular
appendages; however as Chabaud (1975) and
Mollhagen (1976)? state, the spines ale some-
limes very few and/or very small. Mollhagen
ufler examining representatives of many
species, separates the three subgenera by the
absence (Tetramereys) or presence, of dorsal
and ventral labia, and further by the presence
(Petrowimeres) or absence (Gynaecophila) of
interior lateral flanges (lateral cuticular ap-
pendages or cordons of some authors).
In the case of Microtetrameres, a subgenus
Guhernacules has been proposed for species
in Which there is a gubernaculum; this structure
is sometimes distinct, but in many cases jn-
definite, so that this is an unsatisfactory sub-
division, und is not used here,
The specific identification of either Micro-
felrameres spp. or Tetrameres spp. from
females only is, alt the present state of
knowledge, impossible. In cases where only the
female is present im collections listed below,
indentification rests only on similarity to other

females occurring with males. Points con-
sidered in comparison of females are the shape
and size of the buccal capsule and of the egg.
Two of the species described below are from
the Australian pelican. The only record of
Tetrameridae from this host is that of Tetra-
meres pelecani Johnston & Mawson (1942a)
described from one male, and later redescribed
by them (1942b) from three males and a
young female. Mollhagen (1976) considered
T. pelecani incertae sedis, pointing out that
the narrow. buccal capsule and few caudal
papillae described for the single male of the
original description were not typical for the
genus. Further, though the second description
noted more caudal papillae, it also noted the
presence of narrow caudal alae, not otherwise
recorded for the genus, and moreover that
there are discrepancies in the measurements
given in the two descriptions. Recent collections
from pelicans include female Tetrameres and
female Microtetrameres (sometimes in the
same host bird) and with them two species of
male tetramerids, neither provided with body
spines. These males have been compared with
the specimens previously identified as T.
pelecani (Johnston & Mawson 1942a, 1942b).
One is identified as Microtetrameres sp. because
of the number, arrangement, and shape of the
caudal papillae. This is similar to the single
male first described as Tetrameres pelecani,
and this species must now be transferred to
Microtetrameres.
The other species of male is referred to
Tetrameres. The head structure, spicules, shape
of the tail and type of caudal papillae, all
agree with this genus. Although there are
narrow caudal alae, not previously described
for Tetrameres, the specimens are now de-
scribed as a new species of the genus. The
specimens identified as T. pelecani by Johnston
& Mawson (1942b) have been examined and
belong to this species.

species there are four rows of spines, The only
other species in which there are both lateral
flanges and two rows of spines is 7, indiaia
Ali, and in this the left spicule is much shorter
and the spicule ratio less, As the flanges in
T. anseranas ate so poorly developed and may
easily be missed, jt has been compared with
species without flanges but with two complete
rows of spines, but differs from any of these
in the length of the left spicule and the large
body size.

Tetrameres (Gynaecophila) dacelonis n.sp.
FIGS 11-16
Host and localities: Dacelo novaeguineae
(Hermann) from Brisbane, Qld (1 ¢, 20 9);
A.C.T. (2 @).
Male: Length 2.6 mm. Lateral alae present,
from just anterior to cervical papillae to about
two thirds body length. Four rows of well de-
veloped spines, the first at level of cervical
papillae (Fig. 12); dorsal rows end about
1820 ~m from head, and spines in all rows
much smaller, papilla-like and more sparse
from about 1250 »m from head. Oesophagus
580 ym long, its muscular part 210 yr; nerve
ring 130 um, cervical papillae 105 »m, and
excretory pore 190 »m, from anterior end of
worm. Buccal capsule well sclerotised, 12 jm
long, 12 wm maximum external diameter.
Dorsal and ventral labia present, pseudolabia
trilobed. Teeth apparently present, seen only
in lateral view.
Single spicule 280 p,m long, its hilt SO ~m
long (Fig. 13). Tail 115 ym long, caudal
papillae elongate, four pairs subventral, two
pairs lateral.
Female: Gravid female widest anteriorly,
tapering more or less gently to tail, depending
on number of eggs. Total length up to 2.4 mm
(Fig. 14). Oesophagus up to 800 pm long. In
specimen with oesophagus 700 »m, muscular
part of oesophagus 290 ym, distance from
anterior end of nerve ring 170 «wm, of cervical
papillae 80 ym, of excretory pore 135 um.
Buccal capsule barre] shaped, 15 ym long, 11
wm external diameter at widest part.
Body tapering from vulva to rounded point
at tip of 110 pm long tail, with pair of elongate
phasmids 80 »m from tip. Vulva 250 »m from
anus. Embryonated eggs 45-48 »m by 21-22
pm, without opercular or polar filaments.
The only record of Tetrameres sp. from
Alcedinae is of one female, not identified to
species, from Megaceryle alcyon, U.S.A.
(Mollhagen 1976). T. prozeskyi Ortlepp has
been recorded from two hornbills (Lophoceros
spp.) and Tetrameres sp. from Merops sp.
(Borgarenko 1960).
The measurements of the male from Dacelo
are close to those given by Ortlepp (1964)
and Mollhagen (1976) for T. prozeskyi, but
the spines in the latter species start just behind
the head, and are distinctly larger; moreover
there are no dorsal or ventral labia.

Tetrameres gubanovi Shigin
FIG. 17
Tetrameres gubanovi Shigin, 1957, p 256, From
Colymbus cristatus, USSR (2 ¢@).

and Purnong, S. Aust. (8 3, 10 2); Tachybaptus
novaehollandiae (Stephens), Barren Box Swamp,
N.S.W. (2 6, 3 @).
T. gubanovi is the only species recorded in
which there are short longitudinal striae on
each cuticular annulus at the anterior end of
the body, giving a striking appearance (Fig.
17). In the present specimens these striae con-
tinue, becoming less distinct, over about two
thirds of the oesophageal region.
The measurements of the male worms from
the hosts given above are: length 6.5—7.4 mm,
oesophagus 1300-1350 yum, left spicule 4.0-
4.8 mm, right spicule 150-180 ym, spicule
ratio 24-26, tail 380-400 ym. The most an-
terior hooks lie about 300 ,.m from the head;
there are four pairs of subventral and three
pairs of sublateral caudal papillae.

L. Alexandrina (6 ¢, 12 2) S. Aust.; Alice Springs,
N.T. (1 92); P. tabuensis (Gmelin), Langhorne
Creek, S. Aust. (3 &).
The specimens listed above agree generally
with records tabulated by Mollhagen (1976).
The differences are small—the tip of the left
spicule is rounded, not pointed, and there are
very narrow lateral alae. Measurements:
males: 1,9—-2.5 mm long, oesophagus 560-900
um (1/2,8-3.4 of body length); single spicule
190-310 ym long, with hilt 30-38 »m; tail

terior end.
Lateral alae absent, and no somatic spines
observed but two subventral rows of very small
papillae extend from cloaca to about proximal
end of left spicule. Tail rounded at tip, Four
pairs of elongate post-anal subventral papillae
supported by distinct narrow alae and a pair
of lateral papillae on the proximal half of tail
and a pair of phasmids on distal half.
Left spicule 800-1000 ym long, about a
fifth to a sixth body length, with leng cylin-
drical hilt (90-100,m). Right spicule 125-200
pum long. Spicule ratio 5.0-7.7. Gubernaculum
absent.
Female: Largest females somewhat pear-
shaped, with thickest part of body posterior
to midlength. Overall length of body up to 5.5
mm, maximum width 2 mm. Buccal capsule
barrel-shaped, 33-35 ym long, diameter 20-21
pm at widest part. Oesophagus 1400-1900 um
long, its muscular part 310-500 ym long.
Nerve ring 200-300 um from head, Excretory
pore just behind nerve ring.
Body narrows suddenly a little in front of a
vulva, is strongly constricted at vulva, then
tapers to tip of tail; body posterior to vulva
directed dorsally in all specimens (Fig. 25).
Tail 100-120 ,»m long, vulva 200-300 «jm in
front of anus, Embryonated eggs 44-45 ,m
by 20-23 ,m: polar threads absent, thickened
shoulders at each end suggest presence of
opercula but these not visible,
The male of this species is distinguished
from all others described for the genus by the
presence of caudal alae. Apart from the alae,
it seems closest to the four species grouped by
Mollhagen (1976) as the ‘microspinosa group’,
characterised by the absence of lateral alae,
somatic papillae in two incomplete rows, basic
arrangement of caudal papillae four sub-
ventral, one lateral on each side. These species
are T, microspinosa Viguerras, T. buterides
Mollhagen, 7, eleyi Mollhagen and T, flehartyi
182
Mollhagen. The measurements of the Austra-
lian species, and the arrangement of the so-
matic papillae, do not agree with any of
these.
The three male worms from which the
‘amended’ description of T. pelecani were made
(Johnston & Mawson 1942b) have been
examined and appear to belong to T. greeni.

SALINITY TOLERANCE AND OSMOTIC BEHAVIOUR OF EUROPEAN
CARP (CYPRINUS CARPIO L.) FROM THE RIVER MURRAY,
AUSTRALIA
BY M. C. GEDDES
Summary
European carp from the River Murray survived direct transfer to a salinity of 12.5%c and with
acclimation, there was 50% survival at 15%o. In fresh water the carp were hyperosmotic regulators,
and maintained a plasma O.P. of 247 mOsm. At salinites above 10%o they were osmo-comformers
and tolerated plasma levels up to 430 mOsm. The considerable salinity tolerance of European carp
means that they will be able to survive in moderately saline waters in Australia.

Introduction
European carp (Cyprinus carpio L.) have
been introduced into Australia on at least three
different occasions (Shearer & Mulley 1978);
once prior to 1865 near Sydney, then before
1903 into the Murray Irrigation Area, and into
Victoria in the early 1960's, At present Euro-
pean carp from the latest introduction are dis.
tributed over most of the Murray-Darling and
Southeast Coastal Drainage Divisions as desig-
nated in Australian Water Resources Council
(1975). Shearer (1977) believes that the final
range of the carp will also include the North-
cast Coastal, Lake Eyre, Gulf of Carpentaria
and Timor Sea Drainage Divisions. Introduc-
tion into other geographically isolated Drain-
age Divisions is possible, and eventually Buro-
pean carp may be distributed throughout Aus-
tralia, In the River Murray system carp have
undergone @ population explosion over the last
decade with annual catches in South Australia
over the years 1969-70 to 1975-76 of 2000 ky,
10.000 ky, 15.000 kg. 46.000 kg, 146 000 kg,
and 325 000 kg (Olsen 1977). The carp are
often considered a pest because their feeding
habits increase suspended solids and reduce
aguatic vegetation (Shearer 1977), The pre-
sent study outlines the salinity tolerance of
European carp from the River Murray and
describes the osmotic behaviour of carp in
media of varying salinity, This information
may be useful in predicting the ways in which
salinity may limit distribution,
Although basically freshwater fish, cyprinu-
donts show considerable tolerance to water of
increased salinity, Studies on the silver catp
Hypophthalmichthys molitrix (Va\.) and the
grass carp Ctenopharyngodon jdella (Val.) by
Chervinski (1977) show that silver carp sur-
Vive in 20% seawater (7%) and grass carp in
25% seawater (9%), Several species of Cypii-
nodon are listed hy Deacon & Minckley
(1974) a5 occurring at 90%6 and the Death
Valley pupfish, C. milleri, is an osmoregulator
in salinities up fo 105% (Naiman er al. 1976).
Several investigators have comtnented on the
survival of Cyprinus carpie in water of in-
creased salinity, and in reviewing these studies
Black (1957) states that carp cai live indefi-
nitely in water of about one half seawater con.
centration, Al-Hamed (1971) studied salinity
tolerance in C carpio in taq and concluded
that fish survived direct transfer to salinities up
to 12ire and, with acclimation, could survive in
salinities as high as 17%, Martret (1939)
working on C. carpio in Franee, mevsured
lreezing point depression (A) of the blood of
carp in varying salinities. He found that in
freshwater A was 0.50°C, and that the blood
concentration rose to be isosmotie with the
medium at A 0.65°C, and continued up the
osmotic line to A of 1.02°C fcarrespending

to a salinity of 19%), Many of the studies on
salinity tolerance and osmoregulation of this
species have been fragmentary. They have
been examined critically here and compared
with results derived from carp from the River
Murray.
Methods
European carp (200 g-4 kg) were caught
by seine netting in the River Murray at
Walkers Flat in September 1977. Small carp
(<50 g) were collected by trawl net from
Lake Alexandrina in December 1977. All fish
were transported to the laboratory and released
into aerated holding tanks. They were fed fish
pellets during holding and during the experi-
ments, Experimental media were prepared by
adding seawater to de-chlorinated tapwater.
Salinities were calculated from conductivity
measurements using the relationship of Wil-
liams (1966) and are accurate to within +
4%.
Direct transfer experiment: Three fish (200—
250 g) were transferred to each of eight 50 |
buckets containing water of 0.6%—19%« salinity
at 19-22°C. The fish were observed each day
and the survivors counted. Blood samples were
taken at the termination of the experiment or,
in the higher salinities, when fish became in-
active, In association with this experiment two
large fish (2.5 kg) were transferred from
freshwater (0.6%-) to a medium of 11.5%
while two other fish were left in freshwater as
controls, Blood samples were taken at various
intervals after transfer to determine the time
needed for osmotic equilibrium to be re-estab-
lished.
Acclimation experiments: Two acclimation
experiments were conducted, one with mature
fish (1.5-2.5 kg) and the other with juveniles
(<50 g). The experiment with the larger fish
was conducted in two cement tanks measuring
3 x 1 x 0.5 m. In the experimental tank five
fish were subjected to increasing salinity while
in the control tank three fish were kept in
freshwater, At approximately six-day intervals
the survivors were counted, blood samples
taken, and the salinity in the experimental tank
increased. The experiment was run for 38 days
and the temperature range was 16-21°C. The
experiment with juvenile fish was conducted in
two aquaria. The experimental aquarium con-
tained six fish subjected to increased salinity at
approximately eight-day intervals; the control
aquarium contained six fish in freshwater. No

blood samples were taken from these small
fish. Temperature range was 18-24°C,
Blood sampling and determination of osmo-
tic pressure: A 0.2 ml blood sample was col-
lected from the caudal artery using a hepari-
nised 1 ml syringe and a 21 g needle, Blood
was stored in ice and centrifuged at 3000 rpm
for 15 minutes soon after collection. The
osmotic pressure of the plasma was measured
immediately after centrifugation using a
Knauer Semi-Micro Osmometer. Each deter-
mination required 50 pl of plasma. Duplicates
were determined for some samples and were
accurate to within 1%.
Results
Table 1 shows that all carp survived direct
transfer to 12.5%, while only one survived for
six days at 14%. No fish survived above 18%:
(Table 2). The initial mortalities in the experi-
ments were at 13.3%: and 13.1% for the mature
fish and juvenile fish respectively, whereas
50% mortality occurred at approximately 15%«
and 16%: respectively. There were no mortali-
ties in either control.
Figure 1 shows the change with time of the
osmotic pressure (O.P.) of the plasma of carp
transferred from 0.6% (20 mOsm/Kg H,O)
to 11.6% (351 mOsm/Kg H,0O). The O.P.
rose quickly in the initial 24 hours and then
rose more gradually until it reached a new
equilibrium; after approximately eight days the
plasma was isosmotic with the medium, The
O.P. of the control fish fell slightly during the
experiment probably as a result of the repeated
removal of blood,
Determinations of O.P. are shown in Figure
2 and Table 3. In freshwater the carp are
hyper-osmotic regulators with a blood O.P. of
247 mOsm/Kg H, 0. As salinity increases the
blood O.P. is maintained until about 200
mOsm and then rises gradually until it is isos-

The blood O.P. then follows the isosmotic

represent fish that had insufficient time to
acclimate to media of increased O.P. These fish
died soon after the blood sample was taken.
It appears that carp are unable to survive with
a blood O.P. in excess of about 430 mOsm.

Discussion
Mature and juvenile Cyprinus carpio from
the River Murray showed considerable toler-
ance to increased salinity. They survived direct
transfer to dilute seawater of 12.5% and, with
acclimation, the salinity tolerance was raised
lo about 15%. Martret (1939) stated that carp
shows signs of distress at A 0.9°C (approx.
17% and Al-Hamed (1971) showed that 70%
of carp survived direct transfer to 12%. and
with acclimation there was 100% survival at
16%, 80% at 17%- and no survival at 17.5%.
In the present study dilutions of seawater,
188 M. C. GEDDES
having ionic proportions similar to those found
in most Australian inland saline waters and in
estuaries, were used as experimental media.
Although Martret used solutions of NaCl as
experimental media and Al-Hamed used
experimental media of unknown ionic propor-
tions, the salinity tolerances reported are very
similar to those of the present study. It appears
that C. carpio tolerates higher salinities than
do silver carp, Hypophthalmichthys molitrix
(7%), and grass carp, Ctenopharyngodon
idella (9%c) (Chervinski 1977).
Carp are hyperosomotic regulators in fresh
water with a blood O.P. of 247 mOsm. This
blood O.P. is maintained until the external
O.P. increases to 200 mOsm and then rises gra-
dually, so that the fish are isosmotic with the
medium at about 300 mOsm. At higher sali-
nities carp are osmoconformers tolerating in-
creased O.P. of the blood. It appears that
blood O.P, in excess of 430 mOsm is intoler-
able to the cells and so the fish die. Martret
(1939) and Leorey (1938) (in Black 1957)
have measured the O.P. of C. carpio in fresh
water as 263 and 285 mOsm respectively.
Martret measured the isosmotic point at 350
mOsm and the maximum blood O.P. at 480
mOsm, These values are somewhat higher than
those here, possibly reflecting differences
related to the differences in ionic proportions
of the experimental media, osmotic behaviours
of fish from different populations, acclimation,
or in the methods of measuring O.P. The
degree of tolerance to increased blood O.P.
shown by C. carpio may be compared to that
of the halophilic species of Cyprinodon such as
C. milleri, That species survives over the range
fresh water to 105% by regulating the O.P. of
the blood so that blood O.P. rises from 293
mOsm to 503 mOsm while external O.P. rises
from 10 to 3000 mOsm (Naiman ef al. 1976).
The upper level of blood O.P. and the percent-
age increase tolerated, 175% for Cyprinus
carpio and 172% for Cyprinodon milleri, are
similar for the two species.
This study shows that C. carpio is able to
enter moderately saline waters in Australia,
perhaps up to 15%. Al-Hamed (1971) has
shown that eggs of C. carpio develop and hatch
successfully in salinities up to 6.6% and so
breeding populations may be established in
some saline waters. In South Australia, Euro-
pean carp may extend their range into the
Lake Eyre drainage basin where many waters
are slightly saline and the fish fauna is charac-
terized by tolerance to increased salinities
(Glover & Sim 1978). Waters of increased
salinity along the River Murray including lakes
(such as L. Bonney), billabongs and drainage
disposal sites (Engineering and Water Supply
Department 1978) will be suitable habitats for
European carp. In the Coorong lagoon south
of the Murray mouth a salinity gradient from
fresh water to sea water exists and the con-
siderable salinity tolerance of European carp
may allow their partial establishment there.
Although European carp are considered a
freshwater fish they show considerable toler-
ance to increase salinity and this, together with
their tolerance to other environmental factors
such as temperature and oxygen concentration,
means that carp can colonise most waters
throughout Australia. Much more work needs
to be done on factors which may limit distribu-
tion of European carp in Australia and their
ecological consequences.

The plant presently referred to Antithamnion simile (Hooker & Harvey) J, Agardh is
bere replaced in Preretharnnion Nacgeli ay P. simile, a transfer first established by Naegeli
(1861). This genus shows 9 thallus branching pattern similar to that of Platythamnion but
regularly bears only two opposite whorl-branchlets from each axial cell, The relationship of
these tWo genera is discussed. Harvey (1855, 1862, 1863) also recognized planis now
accepted as Platythamnion nadiferum (J. Agardh) Wollaston from the west and south coasts
of Australia as Callitharnnion simile (—Antitharmnion simile) and hence the taxonomic
position of P. nediferum is also discussed
Introduction
Callithamnion simile Hooker & Harvey
(1845) was based upon plants collected by
Hooker from Christmas Harbour, Kerguelen’s
Land, in 1840, Later Harvey (1855, 1862,
1863, Alg, Aust, Exsice., 543) included plants
from the west and south coasts of Australia
under this epithet. However J. Agardh (1876)
separated the Australian plants from C. simile
and recognized then as C. plumula var. ine
vestiens (based on Alg. Aust. Exsice, 543a,
New Holland) and C. nodiferum (based on
Alg. Aust. Exsice., 543D, Port Fairy, Vic.).
Type material for both taxa has been examined;
the former is recognized as Antithamnion
armatun (J, Agardh) De Toni (1903), and
the latter as Platythamnion nodiferum (J,
Agardh) Wollaston (1968). This species de-
velops a much more robust thallus than is
known for congeners and hence it’s identity
is discussed in relation to features characteristic
of the genus,
Type collections of Callithamnion simile
from Kerguelen's Land have been examined
wod the plant found to correspond im morpho-
logical features with Pterothaminion described
by Naegeli (1855) for P. plumula and P.
flaccosum (now recognized as Antithamnion
plunuila and <A. floccasumc tespectively).
Naegeli (1861) recognized differences between
Prerothamnion plumula, the type species of
the genus, and P. floccosum and described the
subgenera Euprerothaimnion and Haplocladium
to accommodate the two taxa. He also included
several species of Callirhamnion in Pleratham-
nion, subgenus Eupterothamnion, including
C, simile from Kerguelen’s Land. Later,
however, J. Agardh (1892) transferred this
latter species to Antithamnion.
This study examines the relationships of
Pterothamnion and Platythamnian, replaces
Antithamnion (Callithamnion) simile in the
former genus as Prerothamtion simile, and
accepts Platythamnian nodiferum as a species
of Platythamnion.

Thallus to 6 cm high consisting of branched,
uncorticated, distichous axes which appear
annular (Fig. I) and bear two opposite whorl-
branchlets from each axial cell (Figs 2, 3).
Whorl-branchlets either unbranched (usually
those of the immature upper thallus) or
bearing a series of adaxial branchlets which
may themselves bear short abaxial branchlets
(Figs 2, 3); usually reduced in length and
branching towards base of thallus. Inde-
terminate lateral branches alternate replacing
whorl-branchlets and distichously placed at
regular intervals of 4—5 axial cells; when young
curved over the growing apex of each axis
(Fig. 2) as in Platythamnion. Axial cells
bearing lateral branches occasionally develop-
ing 1(—2) additional short, simple whorl-
ramulosum
branchlet(s) at right angles to plane of thallus
branching (Fig. 3). Gland cells prominent,
cut off laterally from whorl-branchlet cells of
either adaxial branchlets or, more typically,
rachides near the outer tips; several gland cells
may occur in series from adjacent cells (Figs
2, 3) as well illustrated by Kylin & Skottsberg
(1919, Fig. 35) for Antithamnion ramulosum.
Reproductive structures not observed in detail,
although several, apparently tetrahedrally di-
vided tetrasporangia were found on one of
Hooker’s plants (Fig. 4). Askenasy (1888,
pl. 8, Fig. 4) illustrates rounded groups of
carposporangia and indicates that the carpo-
sporophyte develops on the basal cell of an
elongate whorl-branchlet and that the axes of
the fertile branches may also continue to
elongate as occurs in Scagelia (Wollaston
197la) and sometimes in Platythamnion
(Wollaston 1972).
Type locality: Christmas Harbour. Kerguelen’s

The morphology of Pterothamnion simile
has also been well documented by Dickie
(1879, as Callithamnion simile), Askenasy
(1888, as C. simile), Kylin (in Kylin &
Skottsberg 1919, as Antithamnion ramulosum)
and by Skottsberg (1953, as A. simile). The
present description of thallus structure is based
on collections of Callithamnion simile from
Kerguelen’s Land, including specimens from
the type collection which have recently been
examined, These specimens are in good con-
dition and thallus features are readily observed.
Naegeli (1855) described Pterothamnion
for distichously-branched plants having al-
ternate, indeterminate lateral branches initiated
at near-regular intervals (2—6 axial cells apart)
and with two opposite whorl-branchlets either
simple or adaxially branched from each axial
cell, At that time he included Callithamnion
plumula and C. floccosum in his new genus.
Cramer’s excellent figures (in Naegeli, 1855)
clearly illustrate features characteristic of
Prterothamnion including details such as the de-
velopment of an additional whorl-branchlet on
axial cells bearing lateral branches, as is some-
times seen in P. simile.
On the basis of the above features it is
clear that the plant first described as Calli-
thamnion simile belongs to the genus Ptero-
South Georgia,

thammion, as indicated by Naegeli (1861), and
should be recognized as P. simile,
Naegeli (1861) extended Prerethamnion
(subgenus Euprerothamnion) to include plats
having whorls of more than two whorl-
branchlets arranged so that the two (opposite)
lirst-lormed whorl-brunchlets lay in the plane
of thallus branching, Plants of this form,
hearing Whotls of two opposite major and two
minor whorl-branchlets, were later referred to
anew genus, Platythamnion (J. Agardh 1892).
Similarly plants bearing whorls of four equal
whorl-branchlets have, on the basis of various
combinations of features, been segregated into
uther genera. Prerothammion is thus maintained
for plants which normally develop one pair
of opposite whorl-branchlets per axial cell,
us deseribed by Naegeli (1855),
194 ELISE M. WOLLASTON
Pterothamnion appears to be closely related
to Platythamnion as indicated by similar de-
velopment of a regular alternately branched
thallus. However, in Pterothamnion axial cells
develop only one pair of whorl-branchlets per
cell and whorl-branchlets are often reduced in
form towards the base of the thallus; at branch
apices whorl-branchlets usually remain simple
and unbranched until near mature in length.
In Platythamnion, however, each axial cell bears
two pairs of whorl-branchlets, branching of
whorl-branchlets is increased in the lower
thallus and whorl-branchlet branches are
initiated at an early stage when rachides are
only a few cells long. Also in several species
of Platythamnion, mature whorl-branchlets bear
opposite (e.g. P. heteromorphum, P. reversum)
or tristichous (e.g. P. villosum) branches
whilst, as far as is known, whorl-branchlets of
Pterothamnion are always simple or adaxially
branched, These features suggest that Prero-
thamnion represents a plant form closely allied
to Platythamnion but in which whorl-branchlet
development is restricted both in number of
whorl-branchlets produced and in the branch-
ing pattern of individual whorl-branchlets.
Further observations of fresh material and a
study of reproductive details is necessary to
confirm the relationships of Pterothamnion.
Naegeli (1861) referred to the similarity of
Sporocanthus Kuetzing to Pterothamnion.
However, neither Kuetzing’s drawings nor de-
scription are sufficiently clear to certainly
identify the plant and no material has been
available for checking. Skottsberg (1953)
considered that Antithamnion minutissimum
Levring was the “nearest relative’ of Ptero-
thamnion simile, However Levring (1941) de-
scribed A. minutissimum as a much smaller
plant, to 4 mm high, and gland cells in
Levring’s figures are scattered on whorl-
branchlets and not shown in series near the
tips of rachides such as frequently occurs in
P, simile. However, Levring’s plant resembles
P, simile in bearing opposite, secundly-branched
whorl-branchlets, and his figures indicate that
carposporophytes, like those shown by As-
kenasy for P. simile, develop from the basal
cells of elongated whorl-branchlets and that
fertile axes continue to elongate after carpos-
porophyte initiation.
Another species, Antithamnion antarcticum
Kylin, also bears opposite whorl-branchlets
like those characteristic of Pterothamnion.
However, neither the original description and
illustrations given by Kylin (in Kylin & Skotts-
berg 1919) nor those of Lamb & Zimmermann
(1977) are adequate to confirm generic
identity. Further examination of both A.
minutissimum and A. antarcticum is necessary
to determine the taxonomic placement of these
taxa.
A note on the taxonomic position of
Platythamnion nodiferum (J.Ag.) Wollaston
Platythamnion nodiferum was transferred
from Antithamnion to Platythamnion by
Wollaston (1968) who gave a detailed de-
scription of the plant habit and reproduction.
Platythamnion is distinguished by a com-
bination of features including whorl-branchlets
arranged in whorls of four (two major, which
are adaxially branched in most species, and
two minor), a regular alternate pattern of
lateral branch development and gland cells cut
off laterally from whorl-branchlet cells. In
these features P. nodiferum is similar to con-
geners. It is however a much larger plant [to
20 cm in contrast to a maximum of 6(—8) cm
recorded for other species] with mature axes
densely corticated with rhizoids and bearing
minor whorl-branchlets which are much less
reduced than are those in other species. As
they become older, the minor whorl-branchlets
bear an increasing number of adaxial branches
and in older parts of the thallus they appear
equivalent in form to the major whorl-
branchlets. Similarity of major and minor
whorl-branchlets near the base of the thallus
also occurs in P. recurvatum Wollaston and in
P. villosum Kylin, but in the latter is due to
the loss of the outer part of the rachides of
the major whorl-branchlets (Wollaston 1972).
Rhizoidal cortication of axes in P. nodiferum
is possibly associated with the large thallus
developed in this species. Wollaston (1968)
observed that in this and closely related tribes
of Ceramiaceae rhizoidal cortication was
present in species developing “comparatively
large thalli’”.
In reproductive detail P. nodiferum re-
sembles congeners; however, it develops a
series of up to 20 carpogonial branches at
each fertile branch tip whereas other species,
from the Pacific coast of North America and
from Japan, produce a maximum of only 3—4
carpogonial branches and in some species no
more than one has been observed. Un-
fortunately carpogonial branch development
has not been observed in P. cuspidatum or P.
francisianum recently described from southern
Australia (Wollaston 1978),
RECOGNITION OF PIEROTHAMNION (RHODOPHYTA) 195
ft is of interest te note that a similar con-
trast exists in AMeirwmnion im that species
recorded [rom western North Amenca pro-
duce only 2-6 carpagonitl branches on each
ferjile branch tip whereas Australian species
agam develop up to 20 (Wollaston 1971 b).
Plarviiamnion enypidatune and PL fran
ciskiiuim are much smaller plants (to 2 cm)
that Po nediferwn aod closely resemble non-
Nustralian congeners. In both these specics,
axes ie ufivorticated and major and minor
whorl-branehlets are distivetly different In
Tength and form (Wollaston 1978). PF. noadi-
introduced to this region, This however seems
unlikely since both species are clearly distinct
from previously-described northern hemisphere
species.
Plal\thamnion nodiferum \s common along
the southern coast of Australia and at least for
the present must be regarded as an unusually
robust and thriving species of this genus.

STRATIGRAPHY AND DEPOSITIONAL ENVIRONMENTS OF THE BILLY
CREEK FORMATION (CAMBRIAN), CENTRAL AND NORTHERN
FLINDERS RANGES, SOUTH AUSTRALIA
BY P. S. MOORE
Summary
With the exception of Reaphook Hill, surface outcrops of the Billy Creek Formation comprise three
distinctive lithological units, herein termed the Warragee Member, the Nildottie Siltstone Member
and the Eregunda Sandstone Member. The Warragee Member is the basal unit and comprises
variegated, fine grained siltstone and shale with minor, thin dolomitic interbeds. The overlying
Nildottie Siltstone Member is coarser-grained, and contains an abundance of ripple marks, halite
casts and desiccation cracks. Carbonates and non-red clastics are absent. The Eregunda Sandstone
Member is the uppermost unit of the Billy Creek Formation in the central and northern Flinders
Ranges. It comprises a sequence of fine-grained, current lineated and cross-stratified, greyish red
arkose, with minor interbedded shale and siltstone. The entire sequence is interpreted as a shallow
water, marginal marine to paralic deposit, which spread over the Adelaide ‘Geosyncline’ in
response to tectonic uplift (the Kangarooian Movements) mainly in the south and southeast.

Introduction
The Billy Creck Formation outcrops spo-
radically throughout the central and northern
Flinders Ranges and at Reaphook Hill,
approximately 50 km to the cast (Fig, 1), It
has also been identified in the subsurface of the
Lake Frome region (Daily 1968; Youngs
1978), The formation comprises u Lower to
Middle Cambrian red-bed sequence of shale,
siltstone and sandstone with minor limestone,
dolomite and tuff. Non-red clastics are un-
‘common and oecur mainly in the lower por-
lions of the sequence, Maximum recorded
thickness is slightly in excess of 900 m,
The first direct reference to the sequence
now defined as the Billy Creek Formation was
by Howchin (1907), who suggested that the
red-heds Were dominantly subaerial deposits,
Mawson (1939) also reported on the sequence,
and presented two straligraphic sections de-
scribing outcrops in the Wirrealpa Basin*. ‘The
Billy Creek Formation was finally named and
a type section defined by Daily (1956). Daily's
tvpe section, located approximutely 2.5 kni
north of Ten Mile Creek, is in a similar
position to Mawson'’s (1939) traverse. Daily
(1956) described the Billy Creck Formation
al this locality as a sequence of red-beds 3300
feet (approx. 1000 m) thick, conformably
overlying the Oraparinna Shale, He continued:
‘It consists dominantly of chocolate coloured
micaccous shales, sandstones and siltstones.
The shales occupy most of the thickness and
ure often ripple marked. Pseudomorphs after
halite oceur in the shales in the upper parts
of the formation. Thin bull coloured dolomites
und calcareous shales are common in the lower
1200 feet’,

Billy Creek Formation discussed in detail
and divided into members in this publica-
tion: Mount Scott Range (locality 1),
Brachina (2) and Bunyeroo (3) in the
Heysen Range, Wirrealpa Basin (4), and
Chambers Gorge/Mt Frome (5).
In a summary of the environment of de-
position of the Billy Creek Formation, Dal-
garno (1964) stated that ‘the red argillites of
the Billy Creek Formation appear to represent
a mud flat environment with occasional
incursions of the sea, indicating regression with
large supplies of fine terrigenous clastics. Very
small scale oscillation ripple marks, halite
pseudomorphs and raindrop impressions are
environmental indicators. The last phase of
deposition in this unit is more arenaceous with
cross-bedding, suggesting a deltaic environ-
ment. Thin tuffaceous bands in the lower part
of the formation may be related to vulcanism
in the province to the east’. Daily (1976)
supported this general environmental interpre-
tation, and suggested that ‘a paralic environ-
ment is envisaged, mainly regressive to
Testrictive with evaporitic conditions favouring
red-bed formation under oxidising conditions.
A marine influence is shown by rare trilobite
occurrences in green shale and shallow-water,
foetid limestone and carbonate-rich tuff’.
For all outcrops with the exception of Reap-
hook Hill, this study divides the Billy Creek
Formation into three members, herein termed
the Warragee Member, the Nildottie Siltstone
Member and the Eregunda Sandstone Member
(Fig. 2). The Reaphook Hill sequence is
rather complex and individual in character,
and is not discussed in this publication. The
Edeowie Limestone Memeber, which Dalgarno
& Johnson (1962) defined as the basal member
of the Billy Creek Formation, has been re-
defined as part of the Oraparinna Shale
(Moore 1979),
Dalgarno (1964) subdivided the Billy Creek
Formation into two parts. His ‘lower member’
comprised ‘alternating red and grey-green silts
with minor sandy bands and thin dolomitic
beds’ (Dalgarno 1964) and corresponds es-
sentially to the Warragee Member as defined
herein. Dalgarno (1964) described the upper-
most units of the Billy Creek Formation as
“red brown micaceous sandstones very similar
in character to the Moodlatana Formation”.
However, the lower part of this red-brown
sequence comprises dominantly coarse siltstone,
and thus two members are recognised by the
author; the (lower) Nildottie Siltstone Mem-
ber and the (upper) Eregunda Sandstone
Member.
Stratigraphy of the Warragee Member
Introduction
Throughout the central Flinders Ranges and
in the Mount Scott Range, the lower portion
of the Billy Creek Formation is dominated by
red, green and grey shale and fine to medium
siltstone. Minor interbeds of dolomite, dolo-
mitic limestone, tuff and coarse siltstone are
also present. The sequence is herein termed
the Warragee Member. The name is derived
from the Warragee Bore, located approxi-
mately 20 km northwest of the Wirrealpa
homestead, in the Wirrealpa Basin, The type
section (Section BC-—B, Figs. 2, 3, 4 and Sa)
is located in an area of undulatory topography,
2.5 km north of the Ten Mile Creek. The
section corresponds with the basal 350 m of
Daily’s (1956) type section of the Billy Creek
Formation.
Outcrop of the Warragee Member and lo-
cations of principal measured sections are
shown in Fig. 2. The member attains its
maximum measured thickness of 371 m in
Section BU-—A, south of the Bunyeroo Gorge,
and becomes progressively thinner towards
the north and northeast. It is absent from out-
crops immediately south of the Ten Mile Creek
graben (Section BC—F3, Fig. 2), although
this may be due in part to faulting.

STRATIGRAPHY OF BILLY CREEK FORMATION
The Base of the Warragee Member
In most areas, the Warragec Member rests
conformably on carbonates of the Hawker
Group. Along the Heysen Range, in the central
portion of the Wirrealpa Basin and at Mern-
merna, a pussuge exists from the Edeowie
Limestone Member of the Oraparinna Shale
into the Warrazee Member of the Billy Creek
Formation (Moore 1979). In the northern
portion of the Wirrealpa Basin near the Old
Wirrcalpa Mine, green shales of the Watragee
Member overlie dolomitized Wilkawillina
Limestone With apparent conformity. In the
Mt Scott Range, red and green interlaminated
silty shales of the Warragee Member rest di-
rectly on dolomitized stromatolites of the Ajax
Limestone, also with apparent conformity, At
Mount Frome, the Warragee Member rests
sharply on an uneven surface of very sandy
limestone, presently mapped as Wilkawillina
201
Limestone (Dalgarno & Johnson 1966), and
the contact is interpreted #5 a minor discon-
formity or hiatus. Further to the north near
Chambers Gorge, light olive shales of the
Warragee Member rest conformably on flaggy,
micrilic limestone ot the Moorowie Formation
(Moore 1979),
The Top of the Warragee Member
A transition occurs from the Warragee
Member into the overlying Nildottie Siltstone
Member, In the type section (Section BC-B,
Figs 2 & 4), the contact is taken al the top of

(a) Shale—siltstouve lithotype
The Warragee Member is duminated by
evenly laminated shale and fine to medium
siltstone (Fig. Sh). The majority of the se-
quence is greyish red in colour, although shades
of green und prey are common. Grey to buff
coloured shales are typically weakly calcareous,
afd gradations into dolomite ar dolomitic
limestone may oecur, Coarse siltstone to very
fine sandstone interbeds are uncommon und
occur mainly its thin, evenly laminated inter-
heds in the shaly sequence. Thicker units,
rarely up to 15 em, are ripple laminated (Fig.
Sc), Desi¢cution cracks are uncommon (Fig.
203
Sd), Minor, small (1-6 mm) halite casts are
recorded, especially in the Heysen Range sec-
tions. Tracks allribiled to trilobites occur
sporadically throughout the member. Hori-
gontal and subyertical worm burrows occur
mainly in the upper portion of the Wirrealpa
Basin sequences, and may be found with the
trilobite Balcoracania flindersi (Pocock 1970).
(hb) Carbonate lithotype
Carbonale tunils typically occur in poorly
defined cycles, which grade from red shale
through green and grey shale into carbonate
(Fig. Se). The cycles are best developed in
the Wirrealpa Basin and Mount Frome out-
crops. Dolomite and dolomitic limestone beds
ure typically 2-10 em thick and comprise flat-
laminated to highly undulose dolomicrite to
dolomicrosparite. Halite imprints and desic-
cation cracks are commonly associated with
the flat-laminated units. Undulose laminations
wre altributed to sediment binding on algal
mats. Small. low domal stromatolites are de-
veloped in a few cases, principally in the
Wirrealpa Basin, In the upper portion of the
Wirrealpa Basin sequence, a buff-coloured
dolomite up to 2 m thick may form a
prominent marker horizon. The dolomite is
evenly laminated and contains abundant halite
casts and desiccation cracks.

are uncommon in the Heysen Range sections
and only one has been identified by the author
in the Mount Scott Range.
The tuffaceous units are recognised primarily
on the basis of colour (Dalgarno 1964).
Tuffaceous bands in red shale-siltstone are
either salmon pink or bright olive green. The
pink bands are generally coarse silt-size, and
contain abundant shards of poorly twinned
plagioclase with albitic rims. The green colour
in many of the tuffaceous units is due to ex-
tensive alteration to chlorite. Rarely, devitrified
shards are recognisable.
In the Wirrealpa Basin, two prominent
tuffaceous units, 40-50 cm thick, occur in the
upper portion of the member (tuffs 1 and 3,
Fig. 4). Near Balcoracana Creek (Section
BC-R), tuff No. 1 forms drapes over pre-
existing symmetrical ripples. In the type section
(BC-B), tuff No. 3 is horizontally burrowed
(Fig. 4f) and contains small resting marks
attributed to trilobites. Reworking of some of
the tuffaceous detritus has occurred and several
of the thicker tuff bands contain a variety of
nonvolcanic, sandy detritus. In some cases,
tuffaceous units are ripple laminated with
symmetrical ripples developed on the upper
surface.
Palaeontology
Emuellid trilobites were first recorded in the
Billy Creek Formation by Dalgarno (1964).
The fossil locality is a small tributary south
of Balcoracana Creek, and is shown on the
Blinman 1:63 000 Geological sheet (Dalgarno
et al. 1964). The trilobites were subsequently
described by Pocock (19678, 1970) who
named them Balcoracania flindersi. As now
defined, the trilobites occur in the upper por-
tion of the Warragee Member, “approximately
25 ft below the lowest of three tuffaceous
bands” (Dalgarno 1964).
During the course of this study, additional
collections of Balcoracania flindersi were made
from south of Balcoracana Creek, “approxi-
mately 9 m below a prominent, 40 cm thick,
pink tuff bed, identified as ‘tuff I in Fig. 4.
The trilobites were also found in a similar
stratigraphic horizon north of Balcoracana
Creek (Section BC—R) and in the type section
north of the Ten Mile Creek (Fig. 4). Mass
mortality, associated with desiccation, is indi-
cated in most cases. Despite an intensive
P. S. MOORE
search, trilobites have not been located in any
other outcrops of the Warragee Member.
Regional Variation
The Warragee Member is partly characterised
by its fine grain size and poorly developed grain
size variation. This is true both within and
between sections. Coarse siltstones and fine
sandstones occur mainly in the middle, red
unit of the member and are most common in
the thick Ten Mile Creek graben and Heysen
Range sections (BC-—B, BU-A, BR—A, BR-C).
These sections also contain the greater pro-
portion of red coloured clastics and _ halite
casts.
Carbonate units are particularly common in
the Ten Mile Creek graben outcrops, and
occur sporadically throughout the Wirrealpa
Basin, Mount Frome and Chambers Gorge
sections. They are uncommon in the eastern
areas, such as along the Heysen Range and
at Mt Scott.
Depositional environment of the Warragee
Member
There is abundant evidence of marine in-
fluence throughout the Warragee Member and
most of the terrigenous muds are believed to
have been deposited on the margins of a very
shallow epi-continental sea. Infrequent sub-
aerial exposure is indicated by desiccation
cracks. Furthermore since there is only minor
evidence of evaporite formation, it is likely
that halite and gypsum were only formed in
shallow restricted pools and on supra-tidal
flats. Thus, the presence of halite casts may be
assumed to represent high intertidal to supra-
tidal conditions for those parts of the sequence
in which they occur.
Carbonate units are typically fine-grained
and dolomitic. Their association in some cases
with halite casts and desiccation features sug-
gests that they were deposited on intertidal
flats and in very restricted, shallow lagoons.
Eyaporite minerals have not been found in
association with stromatolitic carbonate, which
probably formed in the subtidal zone or on
intertidal flats subject to frequent inundation.
Soil horizons, massive mudstones and piso-
litic calcrete profiles have not been re-
cognised and thus it is assumed that no sig-
nificant amount of the Warragee Member as

presently exposed was formed by alluvial
flooding in the continental (alluvial plain)
environment. The sequence thus accumulated
by infilling of a shallow epicontinental sea and
progradation of muddy tidal flats. Shale-
carbonate cycles probably developed in re-
sponse to minor imbalance between the rates
of subsidence and sedimentation.
Stratigraphy of the Nildottie Siltstone Member
Introduction
Throughout the central Flinders Ranges and
in the Mount Scott Range, the middle portion
of the Billy Creek Formation is dominated by
greyish red siltstone, with minor shale and fine
sandstone (Fig. 5g). The sequence is herein
termed the Nildottie Siltstone Member. The
name is derived from Nildottie Spring, which
is located approximately 17 km northwest of
the Wirrealpa homestead, in the Wirrealpa
Basin.
The Nildottie Siltstone Member attains its
maximum measured thickness of 460 m in the
Ten Mile Creek graben, but generally thins
towards the north. The type section (Section
BC-B, Figs. 2, 3 and 5a) is located in an area
of undulatory topography, 2.5 km north of
the Ten Mile Creek. It corresponds with the
middle portion of Daily’s (1956) type section
of the Billy Creek Formation.
The Base of the Nildottie Siltstone Member
In most outcrops, the Nildottie Siltstone
Member rests conformably on red and green
shale of the Warragee Member, as discussed
above. However, in the southern portion of
the Wirrealpa Basin south of the Ten Mile
Creek graben, the Nildottie Siltstone Member
rests directly on Wilkawillina Limestone con-
taining Daily’s (1956) Faunal Assemblage No.
2. Although the area is complicated by faulting,
it is possible that the Nildottie Siltstone Mem-
ber originally rested disconformably on Wilka-
willina Limestone.
The Top of the Nildottie Siltstone Member
In all outcrops, the Nildottie Siltstone Mem-
ber is conformably overlain by red micaceous
arkoses of the Eregunda Sandstone Member.
The contact is generally sharp and well defined.
Load structures and flute casts may occur at
the base of the sandstone, especially where it
overlies very shaly sequences.
Internal Stratigraphy
The Nildottie Siltstone Member is dominated
by greyish red, ripple laminated coarse silt-
205
stone. Minor sandstone, fine siltstone and shale
occur sporadically in the lower portion of the
member in a few localities. With increased silt
content, evenly laminated shales grade into
wavy laminated, poorly defined fiaser bedded,
and finally ripple laminated siltstones devoid
of clay laminae. (Fig. 5h). Sandstones are
rare and typically occur as rippled or hori-
zontally laminated units, 5-15 cm thick.
A feature of the Nildottie Siltstone Member
is the abundance of rippled bedding surfaces.
The majority of the ripples are very continuous,
short wavelength (1-3 cm), low amplitude
(4-10 mm), symmetrical and near-symmetrical
forms (Fig. 6a). Highly asymmetrical,
catenary and straight-crested ripples are minor
(Fig. 6b). Mudflakes, desiccation cracks, halite
casts (Fig. 6c) and small load structures are
commonly associated with the silty intervals
and are abundant in some units. Raindrop
imprints are known from several localities (Fig.
6d). Trilobite tracks and worm burrows are
rare. The majority of the sequence is weakly
calcareous, mainly due to a small proportion
of calcite cement. However, some beds con-
tain abundant calcite as vesicles, patches and
veins. A few show evidence of gypsum re-
placement.
Palaeontology
Worm burrows, and tracks attributed to
trilobites are uncommon in the Nildottie Silt-
stone Member. No body fossils have been
found to date.
Regional Variation
The Nildottie Siltstone Member is relatively
consistent in character throughout its area of
outcrop. In the Heysen and Mount Scott
Ranges, the member is divisible into a lower
shaly unit and an upper silty one. In general
however, this coarsening-upward tendency is
poorly expressed. In the eastern outcrops near
Mount Frome and the Chambers Gorge, small
tidal channels are rarely recorded in the
sequence.
Depositional environment of the Nildottie
Siltstone Member
The bulk of the Nildottie Siltstone Member
comprises red shale and shaly siltstone which
were deposited in a paralic environment. A
general lack of cyclicity in the sequence sug-
gests that there was a delicate balance between
subsidence and sedimentation. The considerable
lateral extent and thickness of the paralic
STRATIGRAPHY OF BILLY CREEK FORMATION
facies suggests that the palaeoslope was very
low, and cpeine sea conditions pertained, A
lack of coarse detritus in the sequence is
further evidence of an exiremely low ampli-
tude, senile topography with sediment supply
by sluxgish, low competence streams. This,
an extensive, muddy alluvial flood plain
probably flanked a broad zone of intertidal
sediments,
Intertidal antl shallow subtidal, — tide-
influenced deposits constitute the bulk of the
sequence. Evidence for tidal activity occurs
in the intimate association of wave, current,
flal-topped and interference ripples, along with
desiccation cracks, mudflake breccias, halite
custs, rare marine trace fossils and rain-drop
imprints. In addition, poorly defined wavy and
lenticulur bedding occur in the Nildottie Silt-
stone Member, and are identical in character
to bedding structures in Recent, fine grained
tidal deposits from the Gulf of California
(Thompson 1968),
‘The tidal range during deposition of the
Nildottie Siltstane Member is tnknown, since
there are no palaeotidal range sequences (cf-
Klein 1971). However, the relative abundance
of wave-formed ripples (commonly associated
with desiccation cracks), suggests that tidal
currents were relatively weak. The consistent
bipolar orientation of the ripple marks also
favours a low energy tidal origin for these
sediments, with crests aligned suhparallel to
the coastline and currents directed on and off
shore, The paor sorting of the sediment and a
paucity of tidal channels are further evidence
of weak tidal flax.
Stratigraphy of the Eregunda Sandstone
Member
Jnivoduetion
Throughout the central Flinders Ranges and
in the Mouit Scott Range, the upper portion
207
of the Billy Creek Formation is dominated by
sandstone (Mig. 6c). This sandy sequence is
herein termed the Erevunda Sandstone Mem-
ber, afler Eregunda Creek which dissects the
sequence 7 km west-northwest of the Wirrealpa
homestead.
The Eregunda Sandstone Member altlains its
maximum measured thickness of 166 m in
Section BU—B, south of the Bunyeros Gorge,
and generally thins towards the north and
northeast, The member is absent from Reap-
hook Hill and Mermmerna, where the upper
portions of the Billy Creek Formation ate
missing. due to post-Cambrian erosion. The
type section (Section BC-B, Figs, 2, 3 and
Sa) ts located 2.5 kin horth of the Ten Mile
Creek, Tt corresponds ta the upper 107 mm
of Daily's (1956) type section of the Billy
Creck Formation.

sandstones are minor, and are best developed
in the northern outcrops. along the Mt Scott
Range and at Mt Frome. Trace fossils are
mainly restricted to shaly units, however
molluscan trails, worm burrows and trilobite
tracks are common in evenly bedded to ripple-
laminated sandstones in the Mt Scott Range.
The finer grained sediments of the Eregunda
Sandstone Member comprise greyish red and
rare green, micaceous, feldspathic siltstone and
shale which are very similar to lithologies in
the underlying Nildottie Siltstone Member.
Mudstone intraclasts, desiccation cracks, sym-
metrical ripples and asymmetrical current
ripples are all common in these lithologies.
Halite pseudomorph casts occur at most
localities and tracks attributed to trilobites are
abundant throughout the region (Fig. 6h). The
Eregunda Sandstone Member is generally
divisible into four units (Fig. 2). Units A and
C are dominated by sandstone, whereas units
B and D comprise shale and siltstone with
minor rippled sandstone interbeds.
Palaeontology
Tracks attributed to trilobites are common
in the Eregunda Sandstone Member, and
occur mainly in the fine-grained lithologies
(Fig. 6h). Worm burrows and molluscan trails
are common in the Mt Scott Range outcrops;
however no body fossils have been found in
the member to date.
Regional Variation
The sedimentological characteristics of the
sandstone lithologies vary considerably across
the region, whereas the finer-grained sediments
are relatively uniform in character. A feature
of the sandy sequences is their lateral vari-
ability, and siltstone and shale interbeds cannot
be used to correlate adjacent stratigraphic
sections.
In the Wirrealpa Basin, current lineated
sandstones are prominent, and are commonly
associated with massive sandstones and
erosional surfaces. In the thicker sections along
the Heysen Range, current lineated sandstones
are less abundant, and large scale cross-
stratified and ripple laminated sandstones
occupy an increased proportion of the se-
quence, Near Mt Frome and along the Mt
Scott Range, ripple laminations are common
in the sandstone units, which also contain
P. S. MOORE
trilobite tracks and several prominent bio-
turbated intervals, A general conclusion is that
the thicker sequences of the Eregunda Sand-
stone Member contain a greater proportion of
high energy, current laid deposits.
Depositional environment of the Eregunda
Sandstone Member
Little attempt has been made to interpret
the environment of deposition of the Eregunda
Sandstone Member, although Pierce* suggested
that the sequence in the Wirrealpa Basin
possessed deltaic characteristics. In the course
of this study it became apparent that there
were two clearly distinguishable lithological
associations in the member.
The fine grained, shale-siltstone association
commonly contains marine trace fossils, desic-
cation cracks and halite casts, and is charac-
terised by poorly developed tidal stratification.
A low energy intertidal to shallow subtidal
origin is envisaged. The coarse-grained as-
sociation is dominated by current laid sand-
stones, commonly arranged in waning current
cycles. Ideal cycles display the sequence—
scoured surface, poorly bedded sandstone,
horizontally laminated sandstone, and tabular
cross-stratified sandstone with linguoid ripples
of the upper surface. Marine trace fossils are
very uncommon in these units, although their
abundance increases towards the north and
northeast, where the sand units are thin and
relatively distal with respect to the terrigenous
source area.
The two facies associations are intimately
interbedded. This vertical and lateral juxta-
position of tidal mudflat deposits and current-
laid sandstones indicates that the Eregunda
Sandstone Member was deposited in a shore-
line environment, probably as a complex of
fluvial-dominated deltas which built out into
a shallow epicontinental sea.
Regional correlations
Correlation between the Billy Creek For-
mation and other units in the Adelaide
‘Geosyncline’ and on the Stuart Shelf are
summarised by Daily (1976, Fig. 8). The
Yarrawurta Shale, which was deposited on ‘the
Stuart Shelf to the west of the Adelaide ‘Geo-
syncline’ is similar in character to the Warragee
Member of the Billy Creek Formation, com-
prising approximately 120 m of “micaceous,

of redbed clasties which gave rise to the Yarra-

Thus, the northern porlion of the Adelaide

dicated by much of the Billy Creck Formation

uplift (the Kangarooian Movements) mainly
to the south and southeast of the study area.
Initial tectonic activity associated with the
Kangarooian Movements terminated the major
phase of Lower Cambrian carbonate deposition
(the Hawker Group) and promoted the de-
velopment of muddy tidal flats (the Warragee
Member) on the margins of a much-restricted
basin, Red-beds formed in response to
evaporitic and emergent conditions. Sub-
sequent uplifts increased the palaeoslope, in-
creased stream competence, and released silt
and fine sand into the basin of deposition
forming the sequence herein termed the
Nildottie Siltstone Member. The final uplifts
further increased topographic relief in the
source area and a complex of fluvial-dominated
P. S, MOORE
deltaic sands (the Eregunda Sandstone Mem-
ber) prograded across the basin of deposition.
Palaeocurrent data for the Eregunda Sandstone
Member suggests that the source of the sand
for this unit was the Broken Hill-Olary base-
ment high. The overlying Wirrealpa Limestone
accumulated during a period of relative
quiescence prior to the main phase of red-bed
clastic deposition (the Lake Frome Group)
which probably terminated sedimentation in
the Adelaide ‘Geosyncline’.

A new microdont species of Svhenurus, similar in size to 8. eccidentally, with molar teeth
resembling those of §. gilli is described from Pleistocene cave deposits in southeastern South
Australia,
Introduction
Excavation of the extensive vertebrate fossil
deposits at Victoria Fossil Cave, Naracoorte,
South Australia (Wells 1975) is yielding large
numbers of extinct Sthenurine Kangaroos in-
eluding Procapiodon rapha (Owen), Sthenurus
brownrei Merrilees, 8. occidentalis Glauert, S.
gilli Merrilees, S. atlas Owen, S. cf. andersoni
Marcus and a new form not compatible with
those reviewed by Bartholomai (1963) and
Tedford (1966) or described by Marcus
(1962) and Merrilees (1965, 1967).
The new species is Hamed Sthenurus mud-
docki in memory of the late Ernest Maddock,
past Director of National Pleasure Resorts and
President of the Cave Exploration Group of
South Australia, in recognition of his efforts
in initiating the concept of the Victoria Fossil
Cave tourist complex,
Methods
Mensuration follows Tedford (1966). All
dimensions are in mm X + S.D. L = length:
AW = anterior width protoloph (id); PW =
posterior width metaloph, hypolophid. The
dental nomenclature of Archer (1978) has
been noted; that of Tedford (1966) has been
retained.
Lower juws have been associated with the
skull by a process of elimination based on
tooth dimensions, general morphology and
occurrence in the same stratigraphic horizon.
All referred specimens sre deposited in the
South Australian Museum (SAM).
Diagnosis
Skull: Similar to Sthenurus occidentalis
Glauert (1910) and §. browne? Merrilees
(1967), but differing in the greater lateral ex-
pansion of the frontals.
Mandible; Similar to but larger than that
of §, gilli Merrilees (1965); mandibular sym-
physis long with a pronounced median dorsal
groove and lacking the postero-ventral shelf
of S, gilli and S. occidentalis,
Dentition: Smaller than §. occidentalis or 8.
brownei; similar to, but larger than, 8. gilli;
Tj narrow, lanceolate and procumbent; Pz
narrower in length relative to S. gilli with
labial crest separated anteriorly from lingual
crest by a deep cleft; lophs of My directed
antero-lingually, rather than at right-angles to
saggital plane as in S, gilli, 8. occidentalis and
S. brownet.

Description and Comparison
Skull: (Figs. 1, 2) brachycephalic with ex-
ceedingly inflated frontal sinus produced by
lateral expansion of anterior portion of frontal
bones. This expansion cannot be attributed to
the slight compression and distortion of this
specimen. Facial region and diastema short as
in §. occidentalis. Premaxillary extends antero-
ventrally as prominent horizontal shelf bearing
V-shaped array of incisor alveoli. Narial open-
ing, bounded laterally by narrow vertical wing
of premaxillary, is broader than in S.
occidentalis and similar to S. brownei. Only
collapsed right nasal is present on holotype;
broad and oblate posteriorly, tapering to a fine
point anteriorly, which in an undamaged
specimen would extend well forward of lateral
border of nares. Facial surface of maxillary
narrow but not as deep vertically as in S.
occidentalis and S. brownei. Masseteric pro-
cesses formed mainly by maxillary, short,
blade-like, lack prominent lateral expansion
evident in S. occidentalis and S. brownei.
Orbit more enclosed by overhanging post-
orbital process of frontal than in S. occidentalis,
S. brownei or S. gilli. Jugal forms broad base
and posterior margin to orbital rim. Deep
zygomatic process of squamosal similar to that
of S. occidentalis and S. brownei.
Large palatine vacuities extend anteriorly to
a point opposite median valley of M+.
Sufficient of left palatine bar remains to in-
dicate weak structure similar to that of S.
occidentalis and S. gilli.
Small, paired, incisive foramina open on to
palate opposite posterior border of I# alveoli.
Palate has shallow median groove extending
from incisive foramina, posteriorly to point
opposite anterior root of P?. This groove
flanked on each side by broad depressions ex-
tending from incisive foramina to anterior
border of palatine vacuities. Diastema short,
12 alveolus — P2 30.0 mm, representing 26%
of palatal length (S. occidentalis 25%, Procop-
todon goliah 25%; data derived from
Tedford 1967). Cranium shows some elevation
above plane of palate, not as pronounced as
in S. occidentalis, although similar to S. gilli.
Top of cranium narrow relative to frontal
portion of skull, has two temporal lines which
arise anteriorly from parietals near frontal-
parietal suture and extend posteriorly to con-
verge as saggital crest. Although somewhat
distorted by crushing, occipital region broad
with relatively short paroccipital processes.

Lower Jaw: Mandibles (Pigs. 4, 5) short and
stoul, similar to S. eecidentalis, but with pro-
nounced distal upward curving of tooth row.
Long and gentle sloping symphysis, extending
tO point Opposite posterior root of Pz, lacks
postero-ventral shelf characteristic of S. gilli
and 8, accidentalis (Pig. 6). Two elongate pits
for insertion of genial masculuture occur on
lingual and posterior portion of symphysis,
and u median dorsal grooye extends anteriorly
to incisor alveoli, Anterior mental foramen
opens ahead of Pz and below groove for
buccinator musculature. Buccinator groove a
prominent feature in Simosthenurines (Murray
& Wells in prep.), arises at incisor alveolar
border, sweeps posteriorly in a shallow are
above mental foramen and descends to point
below anterior root of Ms. Posterior mental
foramen opens in mid-lubial aspect of mandible
below anterior toot of My. Digastric sulcus
hegins below the anterior root of Mg, is deep
dorso-ventrally and similar io form to that of
§, occidentalis, and not as pronounced as in
S. brownet. Anterior root of ascending ramus
lies opposite anterior part of Mj, as in J. gilli

and nearly horizontal occlusal plane.
Ps; Smallest tooth in lower dentition (L 7.8,
AW 4.8, PW 5.8), A prominent anterior cusp
gives rise to lingual crest with two small cus-
pules. A weak labial crest encloses small
longitudinal basin. There is an incipient de-
velopment of a postero-labial cusp.
Pe; (Fig. 3b) is a highly distinctive feature of
. maddocki. Ti is hartower relative to length
than in either §. gilli, S. brownei or S.

anteriorly from lingual crest by deep clett.
Descending from prominent anterior cusp,
lingual crest is divided into four cuspules by
Vertical grooves m lingual face of crown, and
from these ascends postero-lingual cusp.
Arising from base of postero-lingual cusp,
short labial crest arcs dorsally and labially to
the postero-labial cusp, terminating abruptly
to leave un anteriorly open median valley. The
Median valley is traversed by series of small
ridglets.

ferior faces; condition being most marked in
unworn juvenile (P16513),
Comments
Except for the greatly expanded frontal
regions, the skull of §, maddocki superficially
resembles that of §. occidentalis, Yet even
without the frontal region, it is easily dis-
tinguished by its smaller molar teeth. The
mandibles resemble those of §. occidentalis,
although a cursory glance at the molars also
suggests §. will, However closer examinition
of the distinctive Pz, the symphysis, and/or
the incisors immediately distinguishes it from
these species. The functional aspects of the
morphological differences will be discussed
elsewhere (Wells & Murray in prep,).
All referred specimens are from the Victoria
Fossil Cave complex. but $. maddocki recently
has been recovered by one of us (Wells) from
# submervedt cave at Tantanoola in southeast
South Australia.
