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:

C. F. Casella & Co. Ltd., Regent House, Britannia Walk, London N1 7ND and

Air Photo Supply Corpn., 158 South Station, Yonkers, New York 10705. U.S.A.

ON HETEROCYPRIS LUZONENSIS NEALE sp. nov.

by John W. Neale

(University of Hull, England)

Heterocypris luzonensis sp. nov.

Holotype: University of Hull coll. no. HU.308.R.la, b, .9 LV, appendages and soft parts.

[Paratypes: University of Hull coll. nos. HU.308.R.2 - 8 (two 66, five 99)] .

Type locality: Flooded soil in rice fields at the International Rice Research Institute Farm, Los Banos area, Laguna,

Luzon I., Philippines, (14° 10' N, 121° 15' E).

Derivation of name: From the island of Luzon in the Philippines.

Figured specimens: University of Hull coll. nos. HU.308.R.la, b (a, 9 LV: PI. 8, 80, fig. 1 ; b, Text-figs. 1, 2), HU.308.R.2a (d

fig. 2).

Diagnosis: Smooth to faintly pitted Heterocypris with valves moderately densely covered with fine setae and greatest

height at or a little in front of mid-length in left valve and at or a little behind mid-length in right. Right

valve tapers and is more narrowly rounded anteriorly than posteriorly; anterior and posterior margins in

this valve are finely dentate. Zenker’s organ with 38 to 41 rosettes.

Heterocypris luzonensis (3 of 8)

Remarks: This species differs from all species of Heterocypris and Cyprinotus so far described from the Philippines.

It differs from that well known tropical species H. dentatomarginatus (Baird) in the shape of the valves

and in having the marginal denticulations in the right valve and not the left. It differs from that other

commonly recorded species H. incongruens (Ramdohr) in the greatest height of the valves being situated

more centrally, the greater elongation of the valves, the apparently more slender pointed lappets of the

copulatory appendage, the proportions of the furca and in various other details of the appendage

anatomy. Comparisons with other species are not close. There is a marked size difference between the 99

(1328 to 1412 pm) and the 66 (1092 to 1176 /im). The fifth pair of limbs in the male shows the usual

strong asymmetry of the left and right claspers found in the genus.

Distribution: This species has so far been found only in the Philippines where it is present in some abundance. Thanks

to the kindness of Dr. Ian F. Grant I had the opportunity of examining this monospecific fauna from the

type locality where it was collected from fresh water between the surface and 15cms deep. By day the

temperatures reached 35°C, dropping to 23°C at night. Dr. Grant informs me that not only is this the

dominant ostracod species but, excepting the Mollusca, it is also the dominant invertebrate. He attributes

its success in the agrochemically treated Fields of the IRRI and the rice bowl of Central Luzon to its

exceptional resistance to pesticides.

Besides the figured material, dry mounted material and spirit material have been stored in Hull

and slides containing valves and dissections of soft parts have been deposited with Dr. Grant at the Boyce

Thompson Institute, Cornell University, Ithaca, N.Y., U.S.A.

(Australian National University, Canberra)

Eucypris fontana (Graf, 1931)

1931 Cypris fontana sp. nov. H. Graf, Zool. Anz., 93, 186, fig. 1.

Type locality: Freshwater pond fed by a spring above Grytviken, S Georgia, Antarctica; for details see Pesta (Ann.

Naturhist. Mus. Wien, 42 1928).

Figured specimens: Brit. Mus. (Nat. Hist.) nos. 1981.295 (9 LV and RV: PI. 8, 88, figs. 1, 2; Text-figs. 1 c, f, 2h), 1981.296

bottom of Twisted Lake, both lakes are on Signy Island. All specimens collected by the British Antarctic

Survey.

Diagnosis: Shell a flattened ellipsoid in lateral view; greatest height between 1/3 and 1/2 from anterior of shell;

dorsum behind point of greatest height gently inclined; anterior of shell more rounded than tapered but

still rounded posterior. Juvenile shell with obvious reticulation except around central muscle area.

Zahnborsten on 3rd maxillular palp toothed. Right furca without anterior seta; anterior claw on

each furca almost twice length of posterior one; posterior seta smaller than posterior claw and placed at

some distance from it.

Eucypris fontana (3 of 6)

Remarks: This species is easily recognised as a Eucypris, possessing the characteristic knobs on the outside of the

shell near the anterior margin (where the shell is slightly pinched — best seen in dorsal view); the left valve

also overlaps the right ventrally. The position of the selvage and the structure of the inner lamella in

E. fontana are also typical of Eucypris species.

It is surprising to find that the right furca of E. fontana does not possess an anterior seta — an

unusual phenomenon among eucyprididid ostracods.

The colour of the shell is green to pale green when preserved in alcohol. Males are unknown.

Grafs (1931) specimens from South Georgia are much smaller (1.1mm and 1.25mm) than those

from Signy Island (1.45mm to 1.30mm). Such difference is not surprising as it is known that important

size differences can be found between populations collected at different times of the year from the same

lake.

Additional specimens, some undissected, from Signy Island are deposited in the Brit. Mus. (Nat.

Hist.) under the following nos. 1981.302 - 308. 1 thank R. B. Heywood for the loan of these specimens.

Distribution: Known from the type locality and as collected by the British Antarctic Survey from 3 lakes (Moss,

Sombre, Twisted L.) on Signy Island which is some 5° Lat. further south than S Georgia. Details on all 3

lakes and their biota is presented in Heywood, et al.

(Freshwat. Biol. 10 47 - 59 1980). It is interesting to note that at least another crustacean, the

copepod Pseudoboeckella poppei is also found in the same localities on S Georgia and Signy Island where

E. fontana occurs.

Reticypris pinguis (3 of 8)

Diagnosis: Outline of hemipenis with lateral lobe boomerang-shaped, inner lobe digitate, broadest at base. Furca with

(cont’d.) 2 equal claws and posterior seta longer than anterior one and about half the length of claws. Zenker organ

with 13 to 15 rosettes.

Remarks: All Reticypris species described from Australia have recently been reviewed by De Deckker, (Trans. R.

Soc. S. Aust., 105, 1981). The obvious differences between R. pinguis and all other known species are

seen with the dorsal bosses, the denticulated flange on the posteroventral edge of the right valve and the

outline of the lobes of the hemipenis. The extent of the dorsal bosses and of the denticulation of the right

valve is variable but these features are always present. The significance of these variations is thought to be

ecological.

The colour of the shell of R. pinguis is pale green.

Additional specimens, some undissected and preserved in alcohol, of R. pinguis are deposited in

the Australian Museum under the nos. P 32011 - 32012.

Distribution: So far R. pinguis has only been found living in Lake George. There, it has been collected at different

salinities (16.4%o on 26 February 1981, 35.4%o on 27 March 1981, 24%o on 11 May 1981, 13 9%o on

2 July 1981 and 4.0 %o on 27 August 1981). It is therefore a euryhaline ostracod sensu De Deckker, 1981

(Hydrobiologia, 81/82, 134).

Fossil specimens of R. pinguis have been found in a core from Lake George of Late Pleistocene

and Holocene age (see De Deckker 1981, unpublished Ph.D. thesis, University of Adelaide). It also has

been found in a number of samples of Late Pleistocene age from a trench dug at 2km west of the walls on

the lake floor of Lake Mungo, New South Wales (material supplied by J. M. Bowler). It also has been

recovered in samples of Late Pleistocene age from a section dug at Baldina Creek, North of Adelaide,

South Australia (material supplied by D. L. G. Williams).

Notiocypridopsis frigogena (3 of 6)

Figured specimens: Brit. Mus. (Nat. Hist.) nos. 1981.290 (9 LV and RV: PI. 8, 102, figs. 1, 2; Text-fig. Id), 1981.291 (juv.

car.: PI. 8, 102, fig. 3), 1981.292 (9 RV and LV: PI. 8, 102, fig. 4; PI. 8, 104, figs, 1, 4; Text-figs. la,b,

Text-figs, lc, 2c - f). All from Twisted Lake, Signy Island, S Georgia.

Diagnosis: Carapace slightly pinched at posterior end of hinge where a small wedge protruding from right valve fits

into left. Shell finely pseudopunctate dorsally and ventrally; pseudopunctation forms elongated polygons.

Mandibular palp with smooth, long a bristle, (3 bristle thick and club shaped; 7 bristle smooth, similar to

adjacent setae and twice as long as last segment. Poorly chitinized and whip-like furcal claw, with one

small posterior seta.

Remarks: It was felt necessary to erect a new genus for this species which does not possess the typical features of

Cypridopsis: globular shape of shell, denticulation on posteroventral inner lamella of right valve, hirsute (3

bristle on mandibular palp (in N frigogena it is smooth and broader) and pincers on the terminal segment

of the thoracopoda II. A major difference between Notiocypridopsis and the similarly shaped (flattened

in dorsal view and often trapezoid in shape) Sarscypridopsis and Plesiocypridopsis is that the latter 2

genera have a ventral overlap of the right valve over the left. In addition, the structure of the inner

lamellae and the position of the selvage in the latter 2 genera are different from those of Notiocypridopsis.

The shell is white in colour when preserved in alcohol.

Distribution: Apart from the type locality TV. frigogena has since been recorded from 4 lakes on Signy Island; for details

see Heywood et al. ( Freshwat . Biol., 10, 47 - 59, 1980). Material studied here came from Twisted Lake (I

thank R. B. Heywood for loan of material which is now deposited in the BM (NH) under the additional

nos. 1981.307 & 309).

Derivation of name:

Diagnosis:

ON LINDISFARNIA LAEVATA (NORMAN)

by David J. Horne and Thomas I. Kilenyi

(City of London Polytechnic, England).

Genus Lindisfarnia gen. nov.

Type-species: Cy there laevata Norman, 1865.

After Lindisfarne (Holy Island), the type locality of the type species.

Carapace generally rhomboidal in side view with prominent marginal rim which is raised anteriorly,

flattened ventrally and posteriorly, and forms a caudal process. Surface smooth or ornamented with

variously developed pits. Hinge gongylodont with smooth median element. Prominent fulcral point. Four

adductor muscle scars in an arcuate row, concave forward, and a y-shaped frontal scar. First antenna with

six podomeres. Second podomere of third thoracic leg bearing a distal spine as long as the third and fourth

podomeres combined. Dimorphic; male more elongate than female. Male copulatory appendages pear-

shaped with prominent, simply coiled ductus ejaculatorius.

L. laevata (Norman) possesses a first antenna with six podomeres, not five as in Loxoconcha and

Hirschmannia (in which genera it has previously been placed by various authors). It is further

distinguished from these genera by details of the hinge structure, and by the shape and arrangement of the

muscle-scars.

Cythere guttata Norman, 1865 (see Athersuch & Horne, Stereo-Atlas of Ostracod Shells 8,117-

124, 1981) and Loxoconcha turbida G. W. Muller, 1894 should also be included in Lindisfarnia since they

correspond closely to the type-species in details of carapace morphology and soft -part anatomy.

Stereo-Atlas of Ostracod Shells 8,116 Lindisfarnia laevata (10 of 10)

Remarks: L. laevata has long been considered to be a junior synonym of Cythere tamarindus Jones, a species

originally described from the Pliocene (Coralline Crag) of Suffolk, England. Jones’s type slide in the Brit.

Mus. (Nat. Hist.) was found to contain only a fragment of a valve, and we have been unable to find a

single specimen to fit the original description and figures which clearly indicate that in dorsal view the

greatest width is well behind mid-length. The Recent form referred to tamarindus by Brady (1868) and all

subsequent authors is widest at or very near to mid-length, and furthermore is smaller, less strongly

ornamented, and possesses more obliquely rounded anterior and posterior margins than that figured by

Jones. Consequently we consider L. laevata to be the correct name for the species described herein, and

regard the name tamarindus as nomen dubium until such time as material matching Jones’s description

and illustration is found. L. laevata does occur, albeit rarely, in the Coralline Crag; apart from being

slightly higher in relation to length, both males and females are virtually indistinguishable from their

Recent counterparts (see PI. 8, 1 14, figs. 1 - 2).

Loxoconcha cuneiformis Malcolmson (Proc. Belfast Naturalists Field Oub: 261, pi. 25, figs. 1 -

2, 1886), considered by Brady and Norman ( Scient . Trans. R. Dubl. Soc., ser. 2, 4, 186, 1889); to be

synonymous with the present species, has a more posteriorly tapered lateral outline and is widest well in

front of mid-length.

Distribution: Recent; a widespread species in the littoral and sublittoral waters of NW Europe from the Bay of Biscay

to N Norway (Brit. Mus. (Nat. Hist.) coll.); we have not been able to confirm any Mediterranean records.

Quaternary; British Isles (Brit. Mus. (Nat. Hist.) coll, and herein), Holland (Wagner, op. cit., 1957).

Pliocene; Coralline Crag, Suffolk (herein).

Remarks:

Brady & Norman ( Scient . Trans. R. Dubl. Soc., ser. 2, 4, 184, 1889) united Loxoconcha guttata (Norman) with L. granulata Sars,

believing them to be adult and juvenile respectively of the same species. Both Sars (1928) and Elofson (1940) disagreed with this

arguing that the differences in shell sculpture were sufficient to delineate the two species. Elofson, nevertheless, noted the striking

resemblance between the two species regarding their appendages, noting that even the male copulatory appendages showed no notice-

able differences. From our study of a wide range of adult specimens from British and Scandinavian localities, it is clear that the two

forms are indeed conspecific. British specimens show a complete range of variation in ornament, from the coarsely reticulate "guttata"

form (PI. 8, 118, fig. 2), through intermediate forms (PI. 8, 122, fig. 1), to the finely punctate "granulata" form (PI. 8, 120, fig. 2)

which is indistinguishable from Scandinavian examples of “granulata". In addition, male copulatory appendages of ail specimens

examined are identical (text-figs. Id, le). We therefore recognise that both the coarse-and fine-ornamented forms are adult stages of a

single species and unite them under the name L. guttata.

An examination of the type illustrations of Cythere impressa Baird, 1850 ( non M’Coy, 1844) shows that this species is

probably conspecific with L. guttata.

The species is placed in the new genus Lindisfarnia (see Horne and Kilenyi, Stereo-Atlas of Ostracod Shells, 8, 107 - 1 16, 1981)

by virtue of features of both carapace and appendages, including the shape of the shell, the characteristic muscle-scars and smooth

median hinge element, the six-jointed first antenna, and the pear-shaped male copulatory appendages.

Although both coarse- and fine-ornamented forms occur in British waters, only the fine, “granulata" form is known from

Scandinavian localities. At present we can only speculate on the reason for this distribution. Possibly the more robust, coarsely

reticulate form is favoured by the longer “growing season” in British waters; in Scandinavia, with shorter summer periods during which

water temperatures are high enough to permit reproduction and growth, the species may be restricted to the development of the

thinner-shelled, finely punctate form.

To the best of our knowledge, L. guttata does not occur in the Mediterranean; any such records, living or fossil, need to be

carefully checked and compared with such species as Loxoconcha agilis Ruggieri, 1967 and L. dertobrevis Ruggieri, 1967 (both of

which should probably be assigned to Lindisfarnia on the basis of carapace characters). The Black Sea species identified by Caraion

(1967) as Loxoconcha granulata differs in the lateral outline of the carapace and in the shape of the male copulatory appendages.

Distribution: Recent; widespread in the sub littoral waters of NW Europe, from the Bay of Biscay to N Norway (Brit.

Mus. (Nat. Hist.) coll., and herein). Quaternary; British Isles (Brady, Crosskey and Robertson, op. cit.).

Diagnosis: Subgenus of Quadritia with four ventral and four dorsal nodes or lobal spines.

Remarks:

Quadritia Schallreuter ( Geologie 15 (2), 204, 1966) undoubtedly originates from quadrilobate ancestors in which both of the anterior

lobes are in each case dissolved into two nodes. In other lineages they are dissolved into a total of only three nodes e.g. Homeokiesowia

(see Schallreuter, Stereo-Atlas of Ostracod Shells, 6, 75, 1979) or Polyceratella (Sarv, EestiNSV Tead. Akad. Geol. Inst, uurimused 4,

pi. 22, figs. 9, 1 1, 1959). Quadritia (K.) krausei Schallreuter ( Palaeontographica (A) 153 (4/6), 179, 1976) and Q. (K. ) iunior probably

originate directly from the oldest known species of Quadritia, Kiesowia sp. of Henry et al. (Com. Serv. geol. Portugal 57 (1973 - 74),

330, pi. 8, figs. 7 - 12, 1976) (= Quadritia (Krutatia) sp. nov.), from the Llandeilo (Formation de Cacemes, Bucaco, Portugal, and

Formation de Postolonnec, Crozon, Bretagne). The latter species is more distinctly quadrilobate but clearly shows the dissolution into

eight spines which is characteristic of the subgenus Krutatia. In the type-subgenus (Quadritia the dorsal spines are lost during phytogeny.

Of the two known species, the older one, Q. (Q.) octispina (Opik) (Ann. etc. Natur. Soc. Tartu Univ., 43 (1/2), 99, 1937, Publ. geoL

Inst. Univ. Tartu, 50, 35, 1937), is more similar to Q. (Krutatia) in lobal morphology and forms a transitional species in this respect (cf.

Opik, op. cit., pi. 8, fig. 6, pi. 11, figs. 16, 17, or Sarv, op. cit., pi. 12, figs. 9, 10).

Distribution: Upper Viruan and Harjuan of Baltoscandia and the Llandeilo of Portugal and France.

(Baltic Sea); lat. 57° 49.5' N, long. 18° 30.5' E; coll, by Horst Kaufmann in 1975. All specimens are of

Upper Ordovician age.

Diagnosis: Valve length up to c. 1.05mm. Unisulcate. Preadductorial node a distinct, high conical node. Besides this

node and the four ventral (lobal) spines, a further three dorsal spines occur. Anterodorsal spine somewhat

behind anterior cardinal comer, posterodorsal spine distinctly below posterior cardinal corner.

Remarks: Q. (K.) iunior is very similar to Q. (K.) krausei from the Upper Viruan (Middle Ordovician) of

Baltoscandia, which has the same number of spines but its anterodorsal and posterodorsal spines are

situated directly at the cardinal corners (Schallreuter, op. cit., pi. 36 (1), fig. 4). Q. (K.) iunior extends the

stratigraphic range of the genus from Middle to Upper Ordovician.

Distribution: Ojlemyrflint erratic boulders (Upper Harjuan) of the Isle of Gotland (Baltic Sea) and of the Kaolinsand

(Pliocene — Pleistocene) of the Isle of Sylt (N Frisian Is., N Sea). All Upper Ordovician age.

RV: PI. 8, 136, fig. 3) and 2484 Guv. RV: PI. 8, 136, fig. 4). All from the type locality; coll, by Ulrich von

Hacht, 1980.

Diagnosis: Species of Eolomatella with two cusps, one in front and one behind S2. Female c. 1.02mm long, ventraliy

has two antra or antra-like concavities.

Remarks: The species is characterized by having two cusps. In the type-species, E. veterrima (Schallreuter) ( Geologie

16 (5), 622, 1967), only LI is bulb-like and in E. biloba Qvale (Norsk geol. Tidsskr. 60 (2), 105, 1980 )

no cusps or bulbs are developed.

Of the type-species of Rozmaniella, R. tersa Melnikova (Palaeont. z. 1978 (2), 72 and Palaeont.

J. 12 [1978] (2), 212, 1979), no males are known. (Melnikova op. cit., 73, 212), but the holotype, a

supposed female according to Melnikova, more closely resembles the larger larvae of E. bicuspidata than

the adult females of E. bicuspidata (cf. Melnikova op. cit., pi. 9, fig. 4 and PI. 8, 134, figs. 1, 2). Like E.

biloba, R. tersa lacks bulbs or cusps at the dorsal margin and perhaps the former species is better placed in

Rozmaniella if the type of dimorphism proves to be similar. E. biloba differs from R. tersa by the absence

of a flat, U-shaped furrow between the postero ventral lobe and the posterior spur seen in R. tersa.

The adventral sculptures in Eolomatella are more complicated than in Aloculatia Schallreuter

(NeuesJb. Geol. Palaont. Mh. 1976 (4), 230) (here considered a senior synonym of Crenabolbina Qvale,

op. cit., 103). Aloculatia possesses a simple velar antrum and does not have a supravelar antrum as was

stated by Qvale ( loc . cit.); in this respect it is very similar to Semibolbina Jordan (see Schallreuter,

Palaeont. z. 51 (1/2), 1977), the main difference between these genera being that the dimorphism is

loculate in Semibolbina and botulate (= non-loculate) in Aloculatia.

Eolomatella bicuspidata (5 of 8)

Remarks: In Aloculatia the spine- or spur-like posteroventral lobe is discrete and not incorporated into the dolon.

(cont’d.) E. bicuspidata illustrates that likewise in Eolomatella the main part of this lobe is also discrete (PI. 8, 130,

fig. 2; PI. 8, 136, fig. 3) and that it therefore represents not a histium but a ventral spine-like crista

(= carina). The anterior part of the main adventral sculpture (PI. 8, 130, fig. 3) and its prolongation

posteriorly, the outer antral fence of the inner antrum (PI. 8, 130, fig. 2), presumably represents a velum.

However, the anteroventral part of the main adventral sculpture (i.e. the part with the anteroventral spur)

and its centroventral prolongation (i.e. the outer antral fence of the outer antrum) may be a histium —

similar to that in the tetradellids Lomatobolbina vonhachtorum Schallreuter ( Stereo-Atlas of Ostracod

Shells 8, 51, 1981) and Pentagona veloreducta Schallreuter ( Geologie 16 (5), 621, 1967) in which the

velum behind the confluence of the histial and velar flanges is also ridge-like rather than flange-like. But it

is not quite sure that it is a histium because firstly of the existence of biantral-dolonate forms, for

example Snaidar, in which the only adventral flange forms two dolonate antra side by side (Schallreuter,

Palaeontographica (A) 153 (4/6), pi. 41 (8), fig. 5, 1976) (perhaps a result of total fusion of histial and

velar flange?); and secondly, there are some similarities with the egorovellids, females of which have an

entirely different dimorphism and several adventral ridges with concavities between them which mimic

antra (see, for example, Kanygin, Ostrakody ordovika gomoj sistemy Cerskogo, pi. 14, figs. 1, la, 3, 3a,

4, 6, 6a, pi. 15, figs. 8, 8a; Trudy Inst. Geol. Geofiz. sib. Otd. 71, pi. 1, figs. 1, la, 3, 3a, 5, 5a \Ibid. 128,

pi. 11, fig. 9, pi. 12, fig. 7, pi. 13, fig. 3). The homologies of the velum and histium of the egorovellids

with those of the tetradellids are unknown.

Stereo- Atlas of Ostracod Shells 8, 135 Eolomatella bicuspidata (7 of 8)

Remarks: The ostracod figured by Sarv (Eesti NSV Tead. Akad. Geol. Inst. Uurimused 4, pi. 23, fig. 12, 1959) as

(cont’d.) Sigmobolbina illativis (Neckaja) resembles E. bicuspidata but lacks cusps. Qvale (op. cit., 105) placed

S. illativis of Sarv in Eolomatella and said it has a distinct dorsal plica (op. cit., 106); such specimens,

perhaps therefore, belong within E. bicuspidata.

Adult males of E. bicuspidata are unknown; thus the largest figured larva (PI. 8, 134, figs. 1, 2)

may represent a preadult female (e.g. see posterior ridge) and not a tecnomorph. The males are

presumably similar to the second largest figured larva (PI. 8, 132, figs. 1 , 2).

On the left valve E. bicuspidata has (PI. 8, 136, fig. 2) an inner contact semi-furrow and a very

small posteroventral marginal flange, comparable to that in Semibolbina and other forms (see Schallreuter,

Palaeont. z. 51 (1/2), 37- 38, text-figs. 2, 4.5, pi. 5, figs. 4, 6, 1977).

(University of Hamburg, German Federal Republic)

Genus NAEVHITHIS gen. nov.

Type-species: Naevhithis naevus sp. nov.

Name of the type-species + generic name Hithis (= Latin for the Isle of Hiddersee). Gender feminine.

Unisulcate; S2 rather long, ventrally obsolete. Preadductorial node rather weakly bulb-like. Postero-

ventral lobe distinct, with a spine-like posterior termination; on its ventral side there is a small ellipsoidal

shaped faceted area of unknown function. Female velum is a small flange forming a slightly convex dolon

extending from anterocentral to centroventral valve region. Laterovelar furrow distinct but rather shallow,

continuing posteriorly as a semisulcus. Marginal sculptures ridge-like.

Naevhithis is similar to forms like Hesslandella ? stipula Schallreuter (Neues Jb. Geol. Palaont. Mh. 1971

(7), 426, 1971), from which it is distinguished by the presence of a posteroventral lobe, its longer S2 and

the presence of a laterovelar furrow. The exact systematic position of H. stipula and like forms is at

present unknown (see Schallreuter, 1971, 428).

ON USCOPRIA MEMORIA SCHALLREUTER gen. et sp. nov.

by Roger E. L. Schallreuter

(University of Hamburg, German Federal Republic)

Genus USCOPRIA gen. nov.

Type-species: Uscopria memoria sp. nov.

Derivation of name: Formed artificially by combining letters from the names of the similar genera Unisulcopleura and

Conchoprimitia. Gender feminine.

Diagnosis: Adults very small (less than 0.5mm long), preplete; anterior cardinal corner much larger than posterior

cardinal corner. Unisulcate, sulcus short. Marginal surface rather flat: angle between contact plane and

marginal surface distinctly less than 90°. At the border between the marginal and lateral surfaces there is

a more or less indistinct retention furrow (Retentionsrinne sensu Schallreuter , Palaeontographica (A) 169

(1/3), 15, 1980).

Remarks: The new genus resembles Conchoprimitia but differs by its distinct preplete outline. In this respect

Uscopria resembles Unisulcopleura Schallreuter [Mss. Z. Univ. Greifswald 17 (1968) (1/2), 131, 1969

(Preprint 1968)] , a genus in which the marginal surface is rather steep — the angle between the contact

plane and marginal surface being about 90°. The higher systematic position of Uscopria is uncertain. The

Conchoprimitiidae and Circulinidae both possess a flat marginal surface but an amplete to postplete

outline; the Monotiopleuridae, on the other hand, are characterized, inter alia, by a steep marginal surface.

Maybe Uscopria best represents the basis of a new family.

Cytherelloides longicostata (3 of 4)

Remarks: C. longicostata is very similar to C. sp. A. Oertli (In: Hollister, C. D., Ewing, J. I. et al. (eds.) Initial

Reports of the Deep Sea Drilling Project, 1 1, pi. 2, figs. 29, 30, 1972) from Jurassic deposits of DSDP leg

11 in the western Atlantic. This is interesting because Oertli regards sp. A as a deep water, Tethyan

species, occurring with bathyal forms Bairdia (Akidobairdia) farinacciae Oertli and Bairdia itatica Oertli.

He considers the sediments to be U. Jurassic in age. C. sp. A differs from C. longicostata by having two

short additional ribs in the posterior cardinal angle region, and in the apparent absence of the lowermost

longitudinal rib. It is also smaller, although the only two specimens recovered may both have been pre-

adults. The close similarities in the two specimens suggests a phylogenetic relationship, C. longicostata

representing the M. Jurassic praecursor of C. sp. A where it inhabited littoral to neritic shelf environments

of the epicontinental sea lying to the north of the Tethys. A westerly migration of C. longicostata into

progressively deeper waters, accompanying opening of the Atlantic Ocean from the M. Jurassic onwards, is

postulated. Evolution into the C. sp. A form would have occurred over the 10 to 20 million year period,

morphological change being only slight because, as Oertli pointed out, the sedimentary environment in

which C. sp. A was found was one in which “evolutionary stress” was non-existent.

Distribution: A shallow water form favouring a littoral to neritic environment, occurring within sediments of L. to U.

Bathonian age at several localities in southern England and northern France.

Ptychobairdia limbata (3 of 4)

Remarks: This is the youngest known species of Ptychobairdia which is typically a Triassic genus. Kollmann (Verh.

geol. Bundesanst., 1, 38 - 45, 1963) has recorded one species, P. schaubergi Kollmann, which ranges

beyond the Trias into the Lias in Austria, and Bate & Coleman (Bull. Geol. Surv. G.B., No. 55, 1 - 42,

1975) have recorded an unnamed species from the Lias of the English Midlands. Apart from these, no

other post-Trias species are known.

The presence of a peripheral carina makes this species similar to the genus Carinobairdia

Kollmann, in particular the type-species C. triassica Kollmann. In C. triassica, however, the carina is more

strongly and evenly developed and is equidistant from the valve edges, and in some species e.g.

C. umbonata Kollmann the carina is developed into a very thick swelling. Other features which place the

present species into Ptychobairdia are the low dorsal outline (highly arched in Carinobairdia ) and absence

of the bairdoppilate hinge structure which is common in Carinobairdia. P. circumvallata Kristan-Tollmann

differs by being larger (holotype length 1.71mm), by the absence of marginal spines and having the

surface pitting restricted to that area of shell within the carina only. The single unnamed species recorded

by Bate & Coleman is slightly larger (length 1.05mm) and lacks the marginal spines but in all other

respects appears identical. It is difficult to say with certainty that this is the same species as P. limbata on

one broken specimen but it could certainly represent the British L. Jurassic predecessor.

Apart from the English Lias species, P. limbata represents the first occurrence of the genus

outside the Tethyan province.

Distribution: A shallow water form occurring within M. and U. Bathonian limestones of Normandy.

Terquemula robusta (3 of 4)

Remarks: T. robusta is morphologically close to T. bradiana (Jones) but has certain modifications to the basic four-

rib ornament which are considered sufficient to merit separate specific status. The short anterior rib

present between the third and fourth carinae in T. bradiana is absent; the two short posterior ribs of

T. bradiana are much more strongly developed here and are always present (in T. bradiana the lower of

the two is variously developed and in some forms absent); the intercostate reticulation of T. bradiana is

rather differently developed here — it is a much more open reticulation but the individual murae are much

thicker and stronger. There is a tendency, too, for the reticulate network to be restricted to the anterior

and posterior regions. It is considered that T. robusta is derived from T. bradiana stock (see Sheppard, op.

cit., 1981 for further details).

The U. Oxfordian species, T. multicostata (Oertli) (Rev. Inst. fr. Petrole, 12, 667, pi. 4, figs.

146 - 153, 1957) from a boring in the western Paris Basin, again has the same basic ribbing arrangement

but has a closer network of reticulation and towards the posterior margin the central carina, and the two

either side of it, fuse completely; they do not in T. robusta.

Distribution: Known only from the type locality, depths 39.71 - 42.77m, Frome Clay, U. Bathonian.

Angliaecytheridea calvata (1 of 6)

ON A NGLIAEC YTHERIDEA CALVATA SHEPPARD

gen. et sp. nov.

by Lesley M. Sheppard

(British Museum (Natural History), London)

Genus Angliaecytheridea gen. nov.

Type-species: Angliaecytheridea calvata sp. nov.

Gender: Feminine.

Derivation of name: Latin, Anglia, England, the country of origin + cytheridea.

Diagnosis: Small to medium-sized genus of Galliaecytherideinae: subquadrate carapace with compressed anterior and

posterior marginal borders, posterior caudal process. Left valve larger than right; in right valve a slight

dorsomedian convexity in dorsal margin. Valves overhang ventral margin posteroventrally. Hinge

antimerodont; inner margin and line of concrescence not coincident, shallow vestibules anteriorly and

posteriorly. Marginal pore canals few, straight, widely spaced.

Remarks: The subquadrate shape and compressed margins of this genus are common to many other Bathonian

genera. Glyptocythere Malz, 1962 is perhaps the closest genus to it in external morphology but internally

differs by having an entomodont hinge and in the absence of vestibules. Galliaecytheridea Oertli, 1957 has

a similar male outline but the females are distinctly ovate and there is no caudal process; in

Angliaecytheridea the female dimorph retains the subquadrate shape but is proportionally higher than the

male. The antimerodont hinge, muscle scar pattern, presence of vestibules and possession of only few

marginal pore canals enable Angliaecytheridea to be placed within the Galliaecytherideinae .

The genus is, at present, monotypic.
