Stereo -viewing for users of the Atlas
In order to obtain maximum information and benefit from the use of the Stereo-Atlas it is essential
that the user view the micrographs stereoscopically. Small pocket-sized stereo-viewers are most
suitable for this purpose. Two suppliers are:

ON LESLEY A BATHONICA BATE gen. et sp. nov.
by Raymond H. Bate
(British Museum [Natural History] , London)
Genus LESLEY A gen. nov.
Type species: Lesley a bathonica sp. nov.
Gender: Feminine.
Derivation of name: After Lesley Sheppard, my colleague working on Jurassic ostracods.
Diagnosis: Genus of Trachycytheridae having quadrate to rectangular outline in lateral view: dimorphic. Carapace
compressed in dorsal view. Shell ornamented with ridges, small terminal nodes and distinct eye node.
Hinge weakly entomodont. Radial pore canals straight, few in number. Inner margin and line of
concrescence coincide. Muscle scars having four adductor scars, antero-ventral mandibular scar and large
antero-dorsal frontal scar composed of single, large, elongate scar with smaller, anterior, subsidiary scar.
Left valve slightly larger than right.

Lesley a bathonica (3 of 8)
Remarks: Lesleya bears some external resemblance to Oligocythereis Sylvester-Bradley and it is possible that, as in
Oligocythereis, the frontal scar may be V-shaped in some individuals according to preservation. Lesleya ,
however, differs in lacking the external muscle scar node of the Trachyleberididae and by having simple,
straight radial pore canals fewer in number than exists for Oligocythereis. For these reasons Lesleya
cannot be placed in the Trachyleberididae and appears to fit naturally into the Trachycytheridae. Lesleya
is presently monotypic, the type species: L. bathonica being restricted to the White Limestone/Forest
Marble horizon of the Upper Bathonian.

Stereo-Atlas of Ostracod Shells 5, 85 Lesleya bathonica (5 of 8)
Diagnosis: Carapace small, dimorphic; strikingly ornamented with prominent anterior ridge that runs, in adults, from
eye node, round anterior margin, to extend back along ventro-lateral margin; juveniles often have
incomplete anterior ridge; short, curved, postero-dorsal ridge projects above dorsal margin. Shell surface
smooth, small nodes sometimes present at anterior and posterior ends. Approximately seven anterior
radial pore canals. Muscle scars as for genus. Normal pore canals simple. Left valve overlaps right along
ventral margin.
Remarks: Lesleya bathonica is a small but striking ostracod that is restricted to the Upper Bathonian (Range: top of
White Limestone to Wychwood Beds of the Forest Marble) of the Oxfordshire Area. Ecologically the
species appears to inhabit those levels of the Upper Bathonian that were deposited in shallow water, close
to land and where fresh-water ostracods are associated (washed-in?) with a more marine fauna. It is
possible, therefore, that conditions of deposition were not fully marine and could have been brackish.
Interestingly the three localities from which Lesleya bathonica has been recorded; Croughton,
Kirtlington and Milton-under-Wychwood all lie on a NE-SW line that was probably close to the old
Jurassic shoreline.

Stereo-Atlas of Ostracod Shells 5, 93 Micropneumatocy there brendae (5 of 8)
Remarks: This is the most highly ornate of all species of Micropneumatocythere and is important stratigraphically as
it is used as the index species of ostracod zone 4 in the current zonation of the British Bathonian (see Bate
1978). Smooth forms do, however, occur in which the ornament is totally lacking (compare PI. 5, 90 fig. 1
with PI. 5, 96, fig. 1) and these very closely resemble M. falcata into which they probably evolved ( Stereo-
Atlas of Ostracod Shells 1978, 5 (14) 97 - 100). The two species may be distinguished in two ways:
(1) on dorsal outline; M. brendae is more strongly arched dorsally and has a much steeper posterodorsal
slope.
(2) within the accommodation groove of the left valve of M. brendae can be seen one prominent centrally
situated vertical ridge and one or two smaller, less well defined, ridges on either side (see Text-fig. la).
These structures are not found in M. falcata (see Text-fig. lb), nor indeed in any other species of the
genus. I suggest that they served as an additional reinforcement of the hinge restricting movement of the
valves when closed. Complimentary depressions in the dorsal edge of the right valve have not as yet been
observed, however, due mainly to poor preservation of this part of the shell. The ridges may have
developed as a result of inhabiting the high energy inner-shelf, near-shore environment that was in
existence during Upper Fuller’s Earth times. The coarse ornamentation would support this idea. Evolution
to M. falcata would have been achieved with the smooth forms of M. brendae as an intermediate stage,
and was accompanied by a change in environment to a much quieter shallow-water habitat. Correspond-
ingly the carapace ornament was lost, so too were the ridges within the accommodation groove.

Distribution: A marine species, common in the Upper Fuller’s Earth sequence in SW England at those localities already
listed, and also one occurrence in the Upper Estuarine Series at Norwich, Norfolk, England. This latter
occurence is useful in correlating the marine sequence in the south with the more brackish beds further

aspidoides ammonite zones.

Micropneumatocythere falcata (3 of 4)
Diagnosis: Species of Micropenumatocy there with sickle-shaped dorsal outline in female dimorph; anterior broadly
rounded, posterior triangular. Shell surface smooth with large, widely-spaced normal pore canals.
Remarks: Hinge, muscle scars and radial pore canals as for genus. There are several (at least 6) parallel ridges running
along the ventral and ventrolateral surfaces.
M. falcata is important stratigraphically as its first appearance is used to identify the base of
ostracod zone 6 in the current zonation of the British Bathonian (see Bate 1978). It is considered to have
evolved from smooth forms of M. brendae Sheppard which occur at the top of zone 5 ; indeed an excellent
phylogenetic lineage can be traced from M. brendae to M. falcata : for details see Stereo-Atlas of Ostracod
Shells 1978,5 (13) 89 -96.
M. falcata is considered a marine to brackish -water species, sedimentological and macrofossil
evidence suggesting it favoured a shallow water environment.
Distribution: M. falcata has been found to range from the top of the White Limestone and throughout the Forest
Marble ( discus ammonite zone) in the Oxfordshire, Kent and Dorset areas of S England only.

Apatocythere spinosa (3 of 4)
Diagnosis: Smoothly ovate in lateral outline with concave postero-dorsal margin and rounded, upturned posterior
point. Anterior and posteroventral margins with small spines, best seen on the right valve where they
affect the lateral outline; in the left valve they occur on the inner edge of the flange where they project
inwards rather than laterally. Hinge (PI. 5, 104, fig. 2) typical of the genus. There is a well developed eye
tubercle and strong sexual dimorphism.
Remarks: The external morphology of this species is similar to Schuleridea lamplughi Neale, 1962 (op. cit.) which
occurs in the same beds and which may be regarded as a homoeomorph (see Stereo-Atlas of Ostracod
Shells 5 (16) 105, 1978). It differs in the hinge structure and in the prescence of small marginal spines.
Apatocythere simulans Triebel, 1940 (Senckenbergiana), from the German Barremian, is most easily
differentiated by the shape of the posterior part of the left valve in lateral view.
Distribution: This is a typical Lower Hauterivian species. It occurs in England in fine-grained, marine sediments rich in
pyrite, glauconite and phosphatic material and is also known from East (and probably West) Germany. In
both England and Germany it is associated with such well known species as Cytherelloidea ovata Weber,
Acrocythere hauteriviana (Bartenstein), Paranotacy there diglypta (Triebel), Protocythere hechti Triebel,
P. triplicata (Roemer) and Schuleridea lamplughi Neale.

Schuleridea lamplughi (3 of 4)
trr
Diagnosis: A Schuleridea with asymmetrically rounded anterior margin and upturned caudal termination in the left
valve. The elongated, pitted valves taper posteriorly.
Remarks: Based on external morphology this species is a homoeomorph of Apatocy there spinosa Neale, 1962 (see
Stereo-Atlas of Ostracod Shells 5 (15) 101, 1978), from which it is easily differentiated by the hinge
structure. It also lacks the marginal spines seen on the right valve of A spinosa.
Distribution: Found in the Lower Hauterivian clays in Britain, it also occurs in the shallow neritic and outer sublittoral
sediments of the Lower Saxony Basin of N Germany (Kemper 1971). From the Upper Valanginian and
Lower Hauterivian of boreholes in the Kujawy area, Poland, J. Sztejn (Biul. Inst. geol. 200, 252, pi. 2,
figs. 1, 2, 1967.) has described this or a closely allied species as S. aff. lamplughi and the same author (Biul.
Inst. geol. 211, 86, 1969.) has recorded S.cf lamplughi (not figured) from the Lower Hauterivian of the
Wa\yal brickyard, Central Poland.

Schuleridea juddi (3 of 4)
Diagnosis: Elongate-oval, tapering strongly posteriorly in lateral view and with a prominent eye tubercle. Surface
pitted, but not as strongly as in S. praethoerenensis Bartenstein & Brand, 1959. Strong dimorphism
characteristic of the genus.
Distribution: The species is typical of the marine Berriasian of northern England where it is associated with
Galliaecytheridea teres, Mandelstamia sexti, Cytheroptenna triebeli, Paracypris caendea and
Paranotacy there speetonensis .
O.B. Christensen ( Geosci . Man 6, 105, 1964) states that S. juddi does not occur in the G. teres
zone in the Danish Embayment, where its place appears to be taken by S. praethoerenensis. In Poland,
J. Sztejn (Biul. Inst. geol. 211, 86, 1969) has recorded S. juddi (not figured) from the Lower Hauterivian
of the Wavyaf brickyard but this horizon is anomalously high and the specimens would merit re-examin-
ation. In Portugal, from the Sierra de Sintra and adjoining areas, J. Rey et al. ( C.R . Somm. Seanc. Soc.
Geol. France 5, 153, 1968) have recorded S. aff. S. juddi but this taxon needs further investigation.
Further south, M. Benest et al. ( Geobios , Lyon 10 (2), 215, pi. 9, figs. 8, 9, 1977) have figured as S. aff.
juddi a closely comparable form from the Upper Berriasian of the Lamoriciere Region, Algeria.

England; lat. 54° 10'N. long. 0° 14'40"W, Valanginian, Lower Cretaceous.
Diagnosis: Species of Schuleridea with valves very high in proportion to length, strongly pitted and truncated
postero-dorsally.
Remarks: Papers on the congeneric S. lamplughi Neale, 1962 and S. juddi Neale, 1962 are also to be found in the
Stereo-Atlas of Ostracod Shells (105 - 108, 109 - 112, 1978 respectively).
Distribution: In Britain and Germany this species has not been found outside Valanginian deposits where it is associated
typically with Protocythere hannoverana . In the Danish Embayment it also occurs in the Valanginian but,
in addition, Christensen ( 1973) has recorded it in typically Berriasian faunas from that area.
Babinot et al. (Annls Univ. Provence Sci. 46, 191 et al., 1971) have recorded S. praethoerenensis,
S. cf. praethoerenensis and S. gr. praethoerenensis (not figured) from a number of Upper Berriasian/Lower
Valanginian sections in eastern Basse-Provence, SE France, and P. Donze (in H. Loffler & D. Danielopol
(Eds.), Aspects of Ecology and Zoogeography of Recent and Fossil Ostracoda, Proc. Sixth Int. Symp.
Ostracoda, 445, 1977, The Hague) lists S. aff. praethoerenensis as one of the common species in the
Berriasian neritic facies of the Iberian peninsula and Vocontian Basin. P. Ascoli ( Maritime Sediments Spec.
Publ. 1, 699 et al., pi. 8, fig. 9, 1976) has found a closely comparable form, noted as S. aff.
praethoerenensis , in Berriasian/Valanginian deposits of the Scotia Shelf, Atlantic Canada. This form also
appears to occur in the underlying Tithonian (ibid., 702).

Figured specimens: Brit. Mus. (Nat. Hist.) nos. Io 4780 (holotype, 6 RV: PI. 5, 130, fig. 1 ; PI. 5, 132, fig. 2);Io4781 (9 LV:
PL 5, 130, figs. 2, 3; PL 5, 132, figs. 1, 3). Both specimens are from the type locality, 2m above the base
of the section.
Remarks: C. obstipa sp. nov. differs from C. polygona Doruk ( Stereo-Atlas of Ostracod Shells, 1978, 5, 133 - 136)
and C. meniscus Doruk ( Stereo-Atlas of Ostracod Shells, 1978, 5, 125 - 128, 1978) by the large size of the
fossae producing an almost reticulate ornamentation. Further, the quadrate posterior outline of C. obstipa
contrasts with the narrowly rounded posterior and obliquely angled posterodorsal slope of C. polygona.
The short, broadly rounded anterior end of C. obstipa differs from the elongate anterior of C. meniscus
which has the anterior cardinal angle set well back on the carapace, almost as far back, but not quite, as
the valve centre.
Distribution: This species has so far only been found in the type locality.

by Robin Whatley1, Paul Frame2 & John E. Whittaker3
(University College of Wales, Aberystwyth1 , Robertson Research
International Ltd.2 , British Museum [Natural History] , London 3)
Genus ROCKALLIA gen. nov.
Type -species : Rockallia enigmatica sp. nov.
Derivation of name: From the occurrence and apparent restriction of the type species to Holocene and Recent sediments in
the Rockall Trough.
Diagnosis: Sub rectangular. Both end margins rounded in left valve. In right valve anterior rounded but posterior
bluntly pointed with apex just below mid-height. Dorsal margin straight in female, slightly concave
medianly in male. Ventral margin gently biconvex in left valve; accuminate in posterior third in right
valve. Left valve slightly larger than right with overlap at the cardinal angles and mid-ventrally. Coarsely
reticulate. Vertical element of ribs forming the reticulae dominant and radiating from mid-dorsal position.
Normal pore canals open, few and situated on the ribs. Inner lamella narrow with small vestibulae at each
end. Selvage strong, sub-peripheral. Hinge lophodont. Four vertically disposed adductor scars, all in
contact situated below the mid-point of the hinge margin; single reniform frontal scar.

Rockallia enigmatica (3 of 8)
Remarks: This new genus is difficult to assign with certainty to any group of Ostracoda. Although some 200
specimens have been encountered to date none have well preserved appendages although some have
“mummified” soft parts. The possession of four adductor scars in a vertical line would seem to indicate
cytheracean affinities but the situation of these scars in a dorso-median position, the narrow and primitive
inner lamella and the shape and outline are suggestive of the Platycopina. The genus is, on these grounds,
and in the absence of soft parts, therefore, tentatively referred to the latter suborder despite the fact that
the overlap relationship of the valves militates against this.
Rockallia enigmatica sp. nov.
Holotype: Brit. Mus. (Nat. Hist.) OS 7599, 9 RV.
[Paratypes: Brit. Mus. (Nat. Hist.) OS 7600 - OS 7605] .
Type locality: Rockall Trough, lat. 55°02.53'N, long. 12°02.68'W. Recent, marine, Globigerina Ooze: depth 2,880m.
Derivation of name: Latin aenigmaticus , an enigma: alluding to the perplexing taxonomic status of this species.

Diagnosis: As for genus.
Remarks:
R. enigmatica occurs frequently in Holocene and Recent samples from the Rockall Trough ranging in
depth from 1 ,040m to 4,000m. It occurs commonly in association with various species of Echinocythereis
and Krithe and with Muellerina abyssicola (Sars) and Ambocy there caudata van den Bold.
Distribution: The species seems to be confined to the Holocene and Recent deposits of the Rockall Trough area.

Stereo-Atlas of Ostracod Shells 5, 149 Callistocythere murrayi (5 of 8)
Remarks: The present species has been compared with a great number of Recent European members of the genus,
particularly from the Mediterranean, (colls, of J. Athersuch, G.S. Brady, A.M. Norman, G.W. Muller,
G. Ruggieri and K. Wouters) and is found to be new.
Distribution: C. murrayi sp. nov. is known so far only from the type locality and from a few other tidal creeks in the
British Isles: Cresswell River at West Williamston, Dyfed, SW Wales (collected by J.E. Robinson), and the
following East Anglian localities: River Bure and Breydon Water, near Yarmouth, Norfolk; River Stour at
Manningtree, Essex; and Lothing Creek, Mutford, Suffolk (all from Brady Coll., Hancock Mus., Newcastle-
upon-Tyne, respectively faunal slide nos. U, W, , Y and Fj). Associated fauna in all cases includes
Cyprideis torosa (Jones), Elofsonia baltica (Hirschmann), Loxoconcha elliptica Brady, Cytherura gibba
(O.F. Muller), Leptocythere ilyophila (Hirschmann), L. lacertosa (Hirschmann) and/or L. castanea (Sars).
Such an exclusively brackish habitat for a species of Callistocythere appears to be rare, and is, as far as I
am aware, the first so far reported from European waters. Whatley & Moguilevsky (1975: Bull.
Am. Paleont., 65, 509), however, cite a number of examples in their discussion on the distribution and
ecology of Argentinian Leptocytheridae.
