(LV: PI. 1:44:248, figs. 1, 3), 10 5231 (RV: Pi. 1:44:248, fig. 2).
The specimen figured in Pi. 1:44:246, fig. 1 is the neotype. 10 5229
from drillings off S coast of Turkey, approx. 130 m below the sea floor;
Plio-Pleistocene; presumed shallow marine; approx, long. 35°59'E, lat.
36°37'N. 10 5230 and 10 5231 from drillings off S coast of Turkey, 200 m
below the surface; Plio-Pleistocene; shallow marine; approx, long.
35°45'E, lat. 36°28'N.
Diagnosis: Reticulate, relatively large and rounded fossae.
Remarks: Ruggieri (1962) has distinguished two subspecies C. e. edwardsii and
C. e. runcinata on the basis of some differences in the strength of
ornament. I have . found that variation in the strength of costae, and
the whole reticulum (including the size and shape of fossae) is
continuous throughout the material ranging from Tortonian to Recent and
have been unable to establish the validity of subspecific differentiation.
Sexual dimorphism: males more elongate (see Pi. 1:44:246, figs. 1, 2).
Distribution: A common species of the E Mediterranean; ranges from Upper Tortonian to
Recent. Reported from Italy, Adriatic, S Aegean Islands, Aegean Sea and
from Turkey.

Figured specimens: Brit. Mus. (Nat. Hist.) 10 5226 (RV: Pi. 1:45:250, fig. 1), 10 5227
(LV: PI. 1:45:250, fig. 2; Pi. 1:45:252, figs. 1, 3), 10 5228 (RV:
PI. 1:45:252, fig. 2). 10 5226 and 10 5228 both from a stream cutting
200 m E of Kiligli, Adana, Turkey; Pliocene, yellow sandstone with
abundant mollusca and foraminifera; presumed littoral; approx, long.
35°28'E, lat. 37°08'N. 10 5227 from Crotone, Italy; coll, by G. Ruggieri;
Recent; approx, long. 17°08'E, lat. 39°05'N.
Diagnosis: Distinguished by sharp posterior bend of median undercut carina and by
the lack of surface reticulation.
Remarks: Cythereis hamata is the type-species of the genus Rectotrachyleberis
Ruggieri, 1952; Ruggieri subsequently regarded the genus as a synonym
of Costa, but Van Morkhoven ( Post-Palaeozoic Ostracoda , 1963) claimed
a subgeneric distinction; as the degree of reticulation is variable
even within species , I prefer to follow Ruggieri in regarding the two
genera as synonyms. Sexual dimorphism: males more elongate.
Distribution: Known widely from Miocene to Recent in the E Mediterranean; found also
in Monaco (Recent) . Upper Miocene (Tortonian) , Pliocene, Quaternary and
Recent in Turkey. The earlier (Miocene and Pliocene) forms are smaller
by about 10% than later forms.

Remarks: Many species formerly referred to Cytherura now belong to other genera
within the Cytheruridae such as Semi cytherura and Hemicytherura . I am
not in a position to comment on the Mesozoic and Tertiary forms that
have been placed in this genus, but as far as I am aware no Recent

Diagnosis; Posterior extremity of carapace drawn out into a weak caudal process just
above mid-height. Females and juveniles with a distinct lateral backward-
projecting protuberance in the lower half of each valve. Sexual
dimorphism strong, the males being more elongate but thinner.
Ornamentation reticulate. Internally, inner lamella narrow throughout;
line of concrescence runs subparallel to outer margin.

Stereo-Atlas of Ostracod Shells, 1:50:279 Cytherura gibba (7 of 8)
Remarks: A certain amount of confusion existed in the last century between
Cytherura gibba and Cytherura (now Semicytherura) cornuta Brady, 1868
(op. cit., p. 445) as can be seen from the synonymy above. The latter,
however, has a more pronounced and pointed caudal process, a median
hinge element that is crenulate at both ends and a line of concrescence
which curves strongly forward in the posterior part of the valves. In
addition, the males of Semicytherura cornuta are much wider than the
females presumably in order to accommodate their bulky copulatory
organs. These differences also epitomise the dissimilarities between
the two genera they represent. It is still however curious to note
that the male of C. gibba remains comparatively narrow when the
copulatory appendage (Pi. 1:50:278, fig. 4) comprises over half of the
total soft parts of the ostracod.
Distribution: Ecology: Its ecology is best summarised by Sars, 1925 (op. cit., p. 201)
when he states that C. gibba is "... a brackish -water form, being
found most abundantly in places where the salinity of the water is much
reduced". Living records suggest that it is confined to the coasts of
the British Isles, NW Europe (N as far as S Norway) and the Baltic.
Stratigraphical range: Pleistocene - Recent.

Nat. Grid Ref.: SP 535122. IO 5973-4 from White Limestone, Milton-under-
Wychwood, Oxfordshire; Nat. Grid Ref.: SP 255156.
Diagnosis: Eye tubercles low; two stubby ventro-lateral alae developed on each valve.
Remarks: The hinge of Marslatourella has always been regarded as antimerodont
(Malz, Senckehberg. leth. , 1959, Bate 1967) but scanning electron-
micrographs now reveal that the dentition of the median element becomes
coarser terminally as in the genus Cxjtheropteron. The hinge type is
artioperatodont (Bate, Palaeontology , Spec. Paper no. 10, 85 pp. , 27 pis.,
1972). The frontal muscle scar may be either rounded or crescent-shaped.
M. bullata differs from M. exposita Malz by its larger size (M . exposita
has an average length of 0.51-0.59 mm), stubby rather than broad alae
and absence of a distinct anterior marginal border.
Distribution: M. bullata has so far only been recorded from the Middle Bathonian
where it is a good indicator of brackish-water conditions.

Diagnosis: Eye stalked with terminal lens and collar. Two blade-like ventro-lateral
alae and single dorso-median spine on each valve. Small subsidiary dorsal
spines may be developed. Hinge well developed artioperatodont .
Remarks: M. dorsispinata is a very rare ostracod of which only single valves,
largely fragmentary, have been found. Sexual dimorphism observed in
the other species of Marslatourella has not been found here. The
large blade-like dorsal spine and the stalked eye tubercle are
characteristic of this ostracod; only one specimen has been found
having the postero-dorsal spine illustrated. The artioperatodont hinge,
only weakly developed in M. bullata Bate, 1967 (see Stereo-Atlas of
Ostracod Shells, vol. 1, pt. 4, pp. 281-284, 1973), is here strongly
developed. A small subsidiary scar is situated in front of the oval
frontal muscle scar, a variation of the rounded or crescent-shaped
frontal scar recorded from M. bullata.
Distribution: Although M. dorsispinata has been found in the Middle Bathonian Hampen
Marly Beds it is essentially an Upper Bathonian species occurring in
both the Wychwood and the Bladon Beds. As for M. bullata it appears to
favour a brackish -water environment.

PI. 1:54:302, fig. 1), HU. 64. C. 31 ( c" RV: Pi. 1:54:302, fig. 2). All from
the Gingin Chalk, Santonian, Upper Cretaceous of One Tree Hill, Gingin,
W Australia.
Diagnosis: A species with reticulate ornamentation, accentuated longitudinal costae
with disjunct mid-rib and strong postero-ventral projection of posterior
termination of ventral rib.
Remarks: This monospecific genus, not so far found outside W Australia, is a
homoeomorph of Acrocythere hauteriviana (Bartenstein) (see Stereo-Atlas
of Ostracod Shells, vol. 1, pt. 4, pp. 289-296, 1973) with similar
ornamentation and sexual dimorphism. It is most easily differentiated by
the absence of the eye tubercle.
Distribution: Bate (1972) records it from both Santonian and Campanian beds in bore-
holes in the Carnarvon Basin, W Australia. It is a common species in the
fine-grained Gingin Chalk at One Tree Hill where it may form up to 9%
of the fauna.
