Stereo-Atlas of Ostracod Shells 4,81
Heterocyprideis macrotuberculata (3 of 8)
Diagnosis: Strongly and irregularly reticulate with subcentral tubercle strong, prominent and reticulate. Free margin
surrounded by four ridges between which are puncta. Posterior loop subperipheral.
Remarks: All three species of the genus are confined to the Northern Atlantic and Arctic. The present species differs
radically from H. sorbyana (Jones) (Palaeontogr. Soc. [Monogr.J 1856), the latter lacking subcentral
tubercle and peripheral ridges. H. fascis (Brady & Norman, 1889) (Scient. Trans. R. Dubl. Soc. (2) 4), is
more similar but is smaller, less strongly ornamented and has a more peripherally situated posterior loop.
H. macrotuberculata occurs most commonly with H. sorbyana (Jones), Eucytheridea bradii (Norman),
Eucytheridea punctillata (Brady), Elofsonella concinna (Jones), Trachyleberis dunelmensis (Norman),
and several species of Cytherepteron, the most common being C. arcuatum Brady, Crosskey & Robertson
and C. nodosum Brady. This indicates that the species is marine. It has only been recovered from fine
grained sediments and probably inhabits waters of no great depth on the continental shelf.
Distribution: This species appears to be confined to the top 45m of the 130m of the Quaternary succession studied to
date in the Forties Field. It only occurs in large numbers in one sample, at a depth of 22m below the
sediment surface. There are no published records of the species.

Progonocythere reticulata (3 of 4)
Diagnosis: Species of Progonocythere with strongly reticulate shell surface, the ornamentation comprising 4 - 5 sided
pits which increase in size towards the centre of the carapace.
Remarks: This is the most ornate of all Progonocythere species and the oldest of the Progonocythere/Glyptocythere
lineage. Features characteristic of both genera can be seen but the shape and form of both dimorphs so
strongly resemble that of P. cristata Bate, particularly the concave posterodorsal slope well displayed in
the male, that it is here considered a species of Progonocythere. Currently it is used as the index species of
the P. reticulata Subzone (lower part of the discites ammonite zone) at the base of the Bajocian.
Distribution: A marine species. Apart from the type locality where it is a common ostracod it has so far only been
found elsewhere in the Hydraulic Limestone of Kirkham Priory and near Castle Howard, Yorkshire,
England.

Glyptocythere scitula (3 of 4)
Diagnosis: Large subquadrate to elongate species of Glyptocythere. Strongly developed ornamentation of carapace
comprising branching and anastomosing ridges, radiating from dorsal margin. Ventral and ventro-lateral
surfaces ornamented with longitudinal ridges, some of which tend to bend upwards anteroventrally.
Remarks: The dorsal margin in the left valve as seen in the holotype (PI. 4, 96, fig. 1) projects above that of the right
valve and is considerably thicker, almost keel-like. Normal pore canals are large and rounded and
particularly evident in those specimens with more poorly developed ornamentation. Hinge is entomodont.
The specimens figured here all closely resemble the holotype in their diagnostic features. The species,
however, includes many unlike forms and is under review at present.
Distribution: A marine species. Found in the Bajocian as the index species of the G. scitula Zone ( = humphriesianum
ammonite zone) in the upper part of the Grey Limestone Series of Gristhorpe Bay, Cayton Bay, White
Nab, Hundale Point, Ravenscar, Hawsker, Bloody Beck, May Beck, Eller Beck, Harland Beck, Bogmire

Figured specimens: The lectotype and specimen 1975.1250, originally carapaces, were subsequently split into single valves.
(contd.) The lectotype was collected for Brady by T. Blain in 1868 from the type locality. 1975.1249 - 1253 were
collected alive by J. Athersuch in Cyprus during 1973. 1975.1249 - 1251 were taken from shell sand
collected at 40m off Kyrenia, approx, lat. 35°21'N, long. 33°22'E. 1975.1252, 1253 were associated with
the sea-grass Posidonia oceanica in sand off Cape Greco, approx, lat. 34° 59'N, long. 34°05'N, water temp.
22° C, depth 33m, salinity 39%o .
Diagnosis: Single, hollow, domed, ventromedian ala. Surface with subrounded fossae. Male copulatory appendages
distinctive.
Remarks: The opportunity is taken to illustrate clearly this little known species and to show the appendages for the
first time. The specimens in Brady’s collection are smaller and have less pronounced alae than those from
Cyprus.
Distribution: Recent from Tenedos (Bozcaada) (Brady, op. cit.), N Adriatic (Uffenorde, op. cit .), Cyprus (herein) and
as L. xena sp. nov. from the Aegean (Barbeito-Gonzalez, op. cit.). Pleistocene and Pliocene from the

Loxoconcha stellifera (3 of 8)
Figured specimens: 1976.744 - 751 were collected by J. Athersuch during autumn 1973 off the coasts of Cyprus. 1976.744
(contd.) was alive on filamentous algae, Petra tou Romiou, approx, lat. 34° 40'N,long. 32° 37 'E, depth lm, water
temp. 25.5° C. salinity 39%o . 1976.751 was living amongst fine encrusting algae, Kyrenia, approx, lat.
32°19'N, long. 35°20'E, depth 2m, salinity 39%o . 1976.745 - 50 were taken from 0 - 15m in sand at other
localities. 1976.743, from Tunisia, was collected alive by Dr. G. Bonaduce.
Diagnosis: Shape of both sexes similar to Loxoconcha rhomboidea (Fischer), but carapace, particularly of female
more tumid. Shell surface with puncta and small pits. Male copulatory appendages distinctive.
Remarks: Muller’s description and illustrations (Muller, op. cit.) adequately define this species. Therefore, no
neotype need be designated. Muller’s specimens were from shallow water amongst sand and seaweed.
Loxoconcha lata Brady, 1868, was considered as a possible senior synonym, but the types are unknown
and the original description and illustrations are considered so inadequate that the name L. lata is regarded
as a nomen dubium.
Distribution: The following records can be confirmed. Recent: Italy (Muller, op. cit.), Tunisia, Cyprus (herein), Israel
(Lerner-Seggev, op. cit.).

Remarks:

Island, approx, lat 35° 42'N, long. 34° 36'E.
A species of Loxoconcha with male recessi and female proboli.
The new term recessus is proposed for the posteroventral sinus of the male (Latin, recess; plural, recessi)
and the new term probolus is proposed for each of the corresponding prominences of the female (Greek,
prominence; plural, proboli).
This species is very similar to Loxoconcha nea Barbeito-Gonzalez (see Stereo-Atlas of Ostracod
Shells 4, 115 - 1 18). L. nea, however, lacks both recessi and proboli. The development of the proboli is
variable; in some specimens there is a single swelling (PI. 4, 126, fig. 1), in others several distinct nodes are
present (PL 4, 120, figs. 2, 3). Some specimens possess an exceptionally strong ornament (PI. 4, 124,
fig. 2; PL 4, 126, fig. 1).
Although no members of this species have been observed copulating, the copulatory position is
assumed to be posteroventral/posteroventral, as with some other members of this genus (e.g. L. elliptica
Brady, pers. comm. Dr. J.E. Whittaker). In this position, with gaping valves, the proboli could be inserted
into the recessi during copulation. This device would provide a more rigid union and possibly bring the
soft parts of the mating pair closer together. This is the first recorded occurrence of pronounced
copulatory adaption of the carapace in Loxoconcha .
Male copulatory appendages similar to those of L. rhomboidea (Fischer), but are more elongate
and differ in their detailed organisation. Females shorter and proportionately higher than males.
Distribution: Recent; known only from Cyprus where specimens have been found alive, associated with algae in shallow
water.

Stravia crossata (1 of 4)
ON STRA VIA CROSS A TA NEALE
by John W. Neale
(University of Hull, England)
Genus STRA VIA Neale, 1962
Type -species (by original designation): Stravia crossata Neale, 1962
Diagnosis: Subtrigonal carapace, left valve strongly overlapping right valve. Marked sexual dimorphism. 16 - 17
straight radial pore canals anteriorly, 20-21 posteriorly. Well-developed merodont hinge overlain by an
accommodation groove in the left valve. Scattered normal pore canals well seen on the inside of the valve
(PI. 4, 138, fig. 3). Frontal scar may be interpreted as a single, triangular, hook-shaped scar opening
anteroventrally or as a larger dorsal with smaller, contiguous ventral scar.
Remarks:
Assigned to the Eucytherinae on the basis of shape, muscle scar pattern, marginal areas and normal pore
canals.

University of Hull. coll. nos. HU.240.R.13 (9 car.: Pis. 4, 140, 142), HU.240.R.3, 4, 1 lb, 12b, (9 limbs).
All specimens from the reservoir Rembewewa, near Nochiyagama, Sri Lanka, c. lat. 8°16'N, long. 80°12'E.
Remarks: This species is easily recognised by its almost circular outline in dorsal view, its flat ventral surface and its
very thin and delicate shell. The latter raises difficulties in S.E.M. work. After a number of specimens had
disintegrated in vacuo, success was only obtained by using a carapace with the complete animal inside.
This thinness of shell is well seen in the three figures of Plate 4, 142. Males of this species have never been
found.
Distribution: Originally described from Madagascar by G.W. Muller, Hartmann (1964) confirmed its occurrence in
Madagascar material from Tamatave and also recorded it in samples from two localities in Hyderabad,
India. However, Reginald Victor, ~who has worked extensively on the Indian fauna, informs me that he
considers that Hartmann’s form is not conspecific with Muller’s species.

Distribution: Brehm [1939 Rev. Zool. Bot. afr. 22 (1) ] recorded C. cf. latissima from the Belgian Congo. Its presence
(contd.) hag recently been confirmed in the Sudan. From collections covering the whole of Sri Lanka, C. latissima
has only been found in three samples from a single locality near Nochiyagama. Here it was common and
associated with Heterocypris dentatomarginatus (Baird), Oncocypris pustulosa Gurney and Stenocypris
major (Baird). In size the Sri Lanka material is closer to the Indian material (length 1.52 mm) than the
Madagascar material (2 mm).

ON TANZANICYTHERE AHMAD nom. nov.
by Manzoor Ahmad
(University of Hull, England)
Genus TANZANICYTHERE Ahmad nom. nov.
1977 Cladarocythere gen. nov. M. Ahmad, A Stereo-Atlas of Ostracod Shells 4, 45.
Type-species (by original designation): Cladarocythere pterota Ahmad, 1977
Derivation of name: From its country of origin, Tanzania.
Remarks: In a recent paper in A Stereo-Atlas of Ostracod Shells (1977, 4, 45 - 48) 1 established the generic name
Cladarocythere (type-species by original designation Cladarocythere pterota Ahmad, 1977). Dr. J.P. Colin
has kindly pointed out (pers. comm.) that Cladarocythere is preoccupied by Cladarocythere Keen, 1972
(Ostracoda).
I therefore propose the name Tanzanicythere nom. nov. to replace the junior homonym
Cladarocythere Ahmad, 1977.
