Kuiperiana robusta (3 of 4)
Diagnosis: Medium-sized, strongly dimorphic with circular to subcircular, regularly disposed punctae
medianly and reticulae peripherally. Dorsomedianly with 3 short, inclined sulcate depressions.
Posterior marginal rim narrow and alar process bluntly rounded. Eye tubercle inconspicuous.
Inner lamella moderately wide, undulose posteroventrally with a wide ventral flange and selvage
and list developed. Hinge gongylodont with a long, thin, smooth groove/bar medianly; the
posterior terminal element of the right valve is a curved tooth with a frill-like dorsal surface.
Remarks: This species differs from the type-species, K. wanneri wanneri (Kuiper, 1918) ( W. N. Kuiper,
Oligocdne und Miocdne Ostracoden aus den Niederlanden, publ. PhD thesis, Groningen, 26-27 ,
pi. 1, figs. 8a-c, 1918 and M.A.A. Bassiouni, Roemeriana, 3, 62-66, pi. 8, figs. 1-3, 1962) in that
its reticulae are less regularly ordered ventrally, its eye tubercle is difficult to distinguish from
ornament (whereas it is well defined in K. wanneri wanneri) and it possesses an alar process. ( K .
wanneri wanneri is inflated ventrally, but lacks a clearly defined alar protuberance). Both species
possess punctate and reticulate ornament and have elongate, subrectangular lateral outlines.
The ratio of adult to juvenile specimens of K. robusta in the authors’ material is low (1:43), with
only 5 adult specimens recovered.
Distribution: Upper Pliocene deposits of St. Erth, England (sample nos. 1-4, 7, 11, 16, 18, 22-23, 25-29) and
Upper Pliocene (Redonian) deposits of Apigne (Borehole II, Le Temple du Cerisier), Le Bosq
d'Aubigny and Saint-Jean-la-Poterie (sample no. 1549.15); NW France. See C. Maybury

Stereo-Atlas of Ostracod Shells 14, 79 Loxocauda subquadrata (3 of 4)
Diagnosis:
Remarks:
Distribution :
A very small to small, subquadrate species of Loxocauda characterised by a lateral surface with 4
obliquely disposed ridges posterodorsally and traces of a reticulum anteromedianly and
anteroventrally ; remainder smooth. Free marginal areas strongly compressed with a prominent,
curved, sub-alar process posteriorly and posteroventrally. Hinge unusual: comprising in the left
valve, a smooth bar with its anterior and posterior ends enclosed by narrow, horizontal,
“u”-shaped sockets themselves bounded by “u”-shaped ridges. Muscle scars comprising four
contiguous adductors, a “v”-shaped frontal and two subcircular mandibular scars.
The genus Loxocauda is known only from three previously described species: the type-species, L.
muelleri Schornikov, 1969 (in: F. D. Mordukhai-Boltovskoi, (Ed.) Identification Key to the Fauna
of the Black and Azov Seas, 2, 201, pi. 28, fig. 1, Kiev, 1969), L. fragilis (Sars, 1866) (G. O. Sars.
Forh. Vidensk Selsk. Krist., 1865, 65-66, 1866 and An account of the Crustacea of Norway, 9,
Ostracoda , pts. 13, 14, 222, pi. 102, fig. 3, 1926) and L. decipiens (G. W. Muller, 1894) (G. W.
Muller, Fauna Flora Golf. Neapel, 21, 347-348, pi. 27, figs. 10-14, 24, pi. 29, figs. 2, 9, 1894). All
these species differ from the new species in that they lack the traces of a reticulum and the sub-alar
process which are characteristic of L. subquadrata. The present species (and all known Loxocauda
species) resemble Pseudocythere Sars in shape and outline. The two genera differ, however, in
their musculature, hingement and appendages.
The species is known only from the Upper Pliocene deposits of St. Erth. Cornwall, England
(samples nos. 1-4, 7, 16, 21, 23, 25-28, C. Maybury, op. cit.).

Stereo- Atlas of Ostracod Shells 14, 87 Sagmatocythere alaefortis alaefortis (3 of 4)
Diagnosis:
Remarks:
Distribution :
A medium, subrectangular subspecies of Sagmatocythere with a straight dorsal margin and strongly
developed alae. Anterior and posterior marginal areas flattened and with ornament less well
developed. Reticulate mid-dorsally and dorsomedianly. Ribs massive and angular in the alar
region of the valve with two deep depressions midventrally. Eye tubercle irregular in outline and
connected with a subrounded, anterodorsal node. Thickened ribs in the posterodorsal area of the
female and male left valve assume a more noded character in the male right valve.
The posterodorsal protuberance/node and irregularly reticulate ornament of this species is similar
to that of certain species of Loxocorniculum Benson & Coleman, 1963 ( Paleont . Contr. Univ.
Kansas., no. 31, 38) such as the type-species, L. fischeri (Brady, 1869) (In: L. De Folin & L.
Perier (eds.), Les Fonds de la Mer, 1(1), 154, pi. 18, figs. 15—16, 1869). The present authors,
however, differentiate the two genera on the basis of their hinge structure: species of
Sagmatocythere possessing a gongylodont hinge with a smooth median element and species of
Loxocorniculum a gongylodont hinge with a strongly denticulate median element.

Stereo-Atlas of Ostracod Shells 14, 91 Sagmatocythere alaefortis gallica (3 of 4)
Diagnosis:
Remarks:
Distribution:
A small subspecies of Sagmatocythere characterised by a straight dorsal margin in female
specimens and a slightly concave dorsal margin in males. The ornament is regularly reticulate with
the majority of fossae circular to suboval in outline. Fossae of the alar region of the valve are
comparatively large and have irregular, angular outlines. In the left valve there is a prominent,
posterodorsal loop; this is less prominent in the right valve. Inner lamella broad with a
conspicuous, blade-like selvage ventrally.
Sagmatocythere alaefortis gallica differs from S. alaefortis alaefortis Whatley & Maybury
( Stereo-Atlas Ostracod Shells, 14, 85-88, 1987) in its smaller size and by having a greater portion of
its lateral surface covered by a reticulum. The reticulum is also more regular in S. alaefortis gallica
than in the nominate subspecies and the posterodorsal protuberance of S. alaefortis alaefortis is
reduced to a posterodorsal loop in S. alaefortis gallica. The distinctive, blade-like selvage of S.
alaefortis gallica also serves to distinguish it from S. alaefortis alaefortis.
This subspecies occurs in the Redonian (Upper Pliocene) deposits of Apigne (Le Temple du
Cerisier) and of Falleron (approx, lat. 46° 60'N; long. 1° 41'W). It has also been recovered in a
mixed sample from NW France, also of Redonian age. See J. -P. Margerel, Les Foraminiferes du
Redonian. Systematique, Repartition stratigraphique, Paleoecologie, Nantes, 1, 8-26, 1968 for

Sagmatocythere wyatti (3 of 4)
Diagnosis:
Remarks:
Distribution:
A small to medium species of Sagmatocythere with an irregularly reticulate ornament of large
fossae and narrow, blade-like muri. There are four obliquely disposed, subparallel muri
posteriorly and a deeply excavated area posteroventrally. Eye tubercle small, smooth, tear-shaped
and connecting with a narrow murus which extends anteroventrally, parallel to the anterior
margin.
This species and the type-species, Sagmatocythere napoliana (Puri, 1963) (see J. Athersuch,
Stereo-Atlas Ostracod Shells 3, 117-124, 1976), a Miocene to Recent Mediterranean species, are
similar in that certain units or ‘cells' of the reticulum can be traced in both species. There is, for
example, a prominent, polygonal posterior unit and a deeply excavated posteroventral area. In
addition, there are 5-7 conjunctive pore conuli anteriorly, the muri of both species are narrow and
blade-like and the fossae comparatively large. The two species differ in lateral outline; S.
napoliana is much more elongate than S. wyatti and, whereas the former species has a dorsal
margin with a concavity or ‘saddle’, the dorsal margin of S. wyatti is straight and obliquely sloped.
In addition to its occurrence in the Upper Pliocene deposits of St. Erth, Cornwall, England
(sample nos. 1, 7, 10, 23, 25, 28-29; see C. Maybury, op. cit., for details), this species has been
found in a Redonian (Upper Pliocene) sample of shell-rich sand from Le Temple du Cerisier, SW
of Rennes (approx, lat. 48° 07'N, long. 1° 41'W), NW France (see, J. -P. Margerel, Les

by John Athersuch & John E. Whittaker
(B.P. Research Centre, Sunbury and British Museum (Natural History), London)
Genus CARINOCYTHEREIS Ruggieri, 1956
Type-species (by original designation): Cytherina carinata Roemer, 1838
Diagnosis: Quadrate trachyleberid with three subparallel ponticulate, sometimes discontinuous carinae;
ventral carina strongest. Ventral margin carinate; anterior margin carinate and/or denticulate;
posterior margin spinose or denticulate; area between carinae tuberculate or mammilate. Male
RV dimorphic; posteroventral region of valve devoid of ventral carina and compressed. Eye
tubercle prominent. Hinge amphidont or heterodont; anterior tooth of RV stepped; posterior
tooth crenulate.
Seta of second podomere of antennula long in both sexes; endopodite of antenna with three

Disgnosis: Anterior margin with marginal carina which is entire and ponticulate throughout. Ventrolateral
carina not produced anteriorly. Male copulatory appendages distinctive.
Remarks: In designating a neotype for Carinocythereis carinata, Ruggieri & Russo (1980, op. cit .) chose a
specimen identical to C. antiquata (Baird) in all aspects except for size. This was particularly
unfortunate since Roemer’s original illustration is so unclear as to make its interpretation entirely
subjective, whereas C. antiquata, although lacking a type specimen, is readily determinable from
Baird’s original drawing. Nevertheless, C. antiquata and the neotype of C. carinata are, in our
opinion, quite clearly conspecific (compare PI. 14, 98, fig. 2 and PI. 14, 100, fig. 1) and as a result
the latter name takes priority.
C. whitei (Baird) (see J. Athersuch & J. E. Whittaker, Stereo-Atlas Ostracod Shells, 14,
103-110, 1987) differs from C. carinata principally in the disposition of the carinae. C. carinata
possesses a marginal carina ventrally which extends without a break from the posteroventral angle
around the anterior margin to the eye tubercle. C. whitei has a similar marginal carina which
occupies the same position, but in contrast to C. carinata, it is replaced anteroventrally by a row of
short, stout marginal spines. In addition, the carina does not form such a prominent crest above
the eye tubercle. Both species possess ponticulate ventrolateral carinae. In C. whitei this carina
extends anteriorly to run parallel to the anterior margin. A similar carina is found in C. carinata
but it is restricted to the ventrolateral region, the anterior part being replaced by a row of four to
five small tubercles. C. whitei is consistently smaller than C. carinata amongst living populations.
Fossil specimens of C. carinata are also significantly smaller than their Recent counterparts. Minor
differences in the male appendages are also useful in distinguishing between these two species.
In the juveniles (A-l, A-2) of both species, the marginal carinae are entire. However,
differences seen in the ventrolateral carinae of the adults are also apparent in the juveniles. In
addition, the juveniles of C. whitei are proportionately less high and more tapered posteriorly then
those of C. carinata.
Stereo-Atlas of Ostracod Shells 14, 102 Carinocythereis carinata (6 of 6)
Distribution: Recent: British coasts, most frequently in the north (BMNH and Brady Collection, Hancock
Museum); French Atlantic Coast (Yassini, 1969, Bull. Inst. Geol. Bassin Aquitaine, 7);
Mediterranean (Pugliese etal., 1978, Pubbl. Staz. zool. Napoli, 40); Black Sea (Caraion, op. cit.).
Pliocene and Pleistocene: Mediterranean (Doruk, op. cit. and herein).
There is some evidence (e.g. Pugliese et al., 1978), at least in the Mediterranean, that C.
carinata (= C. antiquata) tends to occur more frequently in deeper water (40-130 m) than C. whitei
(=C. bairdii) (20-90m).

Remarks: This species was recognised by Baird (1850, op. cit.), Brady (1868, op. cit.) and Brady, Crosskey &
Robertson (1874, Palaentogr. Soc. Monogr.) as being distinct from C. carinata (Roemer, 1838) =
C. antiquata (Baird, 1850). All of these authors, however, illustrated and described poorly
preserved specimens of C. whitei , a fact that has tended to mask the true differences between these
two species. (Worn specimens appear more nodose when the carinae are abraded). However, an
examination of Baird’s syntypes, one of which is illustrated herein (PI. 14, 104, figs 1, 2) leaves us
in no doubt as to the true identity of C. whitei. The main difference between C. whitei and C.
carinata (Roemer) is in the length and disposition of the ventrolateral and anterolateral carinae
(see also Remarks on C. carinata (Roemer) in J. Athersuch & J. E. Whittaker, Stereo-Atlas
Ostracod Shells, 14, 97-102, 1987). There is some variation in the development of the carinae in
both Recent and fossil forms (cf. PI. 14, 106, figs. 2, 3; PI. 14, 108, figs 2, 3), a factor which seems
to be related to calcification of the carapace as a whole.
Until Athersuch, Horne & Whittaker (1985, op. cit.) reinstated the name C. whitei , G. S.
Brady & A. M. Norman (Scient. Trans. R.Dubl. Soc., ser. 2, 4, 1889) were apparently the last
authors to regard it as a distinct species in Britain and the only records under this name in the
Mediterranean appear to be those of Ruggieri, 1956 (Att Soc.ital.Sci.nat., 95) and Uliczny, 1969
(op. cit.). Otherwise, the name whitei seems to have fallen into disuse and specimens referable to
this species have usually been described as either C. antiquata (Baird) or C. bairdii Uliczny.
Distribution: Recent: British coasts (most frequently in the south), French Atlantic coast and widespread
throughout the Mediterranean (recorded as C. antiquata or C. bairdii). A sublittoral species found
at depths of 20-60m or more.
Fossil: Pleistocene and Pliocene of the Mediterranean (under a variety of names) (Uliczny,
op. cit.; Ruggieri, op. cit.); Pleistocene of England (as C. aspera).

Carapace small; dorsal margin straight, inclined towards posterior; ventral slightly concave in the
median part. Highest and widest about one-third length from the anterior end. Surface reticulate
with secondary pitting in the fossae. Two vertical dorsal sulci in the anterior half of the shell, the
most prominent lying just in front of mid-length. Pores occur at the intersections of some muri of
which two or three anteriorly, and about half a dozen posteriorly form fairly prominent pore
conuli. There is a small backward projecting spine at about three-quarters length and at about
one-fifth the height above the ventral margin. Some specimens show a sulcus immediately behind
this spine (PI. 14, 120, fig. 2). Vertical row of four adductor scars placed low on the shell on the
anterior side of the internal ridge, with two rounded mandibular scars more ventrally. Hinge
merodont with straight toothplate subdivided into three toothlets anteriorly, a locellate groove and
a prominent elliptical tooth posteriorly in the right valve.
This species is related to Leucocythere plena Zhao (see Stereo-Atlas Ostracod Shells, 14, 123,
1987), but the latter is more swollen posteriorly, with a concave posterior outline in dorsal view,
and the hinge structure is less well developed.
This species has so far only been found in Pleistocene deposits in Guizhou Province, SW China.
This study was undertaken as a visiting research scholar at the Department of Geology, University
of Hull, England.

Small to medium sized carapace with gently concave dorsum inclined posteriorly. Highest
anteriorly at about one-third the length. Two dorsal vertical sulci in the anterior half of the shell;
sub-central tubercle; posterior half of shell swollen. Sparse pore conuli developed over the surface
of the shell and developed posteriorly where they form distinct tubercles. Ornamentation of
subdued reticulation with round secondary pits occupying the fossae. Ten marginal pore canals
anteriorly. Vertical row of four adductor scars in the ventral part of the shell and lying on the
anterior flank of the median internal ridge which defines the posterior limit of the sub-central
tubercle. Hinge merodont with narrow, well-defined anterior and posterior toothplates with thin,
sinuous groove in between.
This species is closely related to L.weiningensis Zhao (see Stereo-Atlas Ostracod Shells, 14, 119,
1987) but differs in its concave dorsum, less differentiated hinge, subdued ornamentation and
marked posterior swelling. The present species is also related to L.subquadrata Huang & You,
1982 (Huang, Yang & You, Palaeontology of Xizang, Book IV, 377, fig. 6, pi. 14, fig. 3, 1982,
Beijing), but that species lacks the carapace sulci and does not show the posterior inflation of
L. plena.
L. plena has so far only been found in Pleistocene deposits in Guizhou Province, SW China.

represents the expression of the median sulcus internally, frontal scar oval on the same level as the
two uppermost adductors and two rounded mandibular scars more ventrally placed. In dorsal view
pointed anteriorly and somewhat arrow-shaped. Three small dorsal spines in the posterior half of
the right valve.
L. xinanensis is closely related to L.stationis Vavra, 1891 but differs clearly from the latter species
as originally figured ( Archiv Naturw. Landesd. Bohmens, 8, 109, fig. 38, 1891) in being much more
slender and more pointed posteriorly in dorsal view and in tapering more posteriorly and not being
so evenly rounded anteriorly in lateral view. L.stationis was thought to be confined to Europe until
Martens ( Hydrobiologia , 110, 138-141, figs. 9-16, 1984) recorded it from the Sudan and gave
good illustrations, Martens’ material is much nearer to the Chinese material in dorsal view but in
lateral aspect does not taper so much posteriorly and the dorsal margin shows a more pronounced
break in slope than does L. xinanensis where the dorsal margin is long and straight. Martens notes
the variability of dorsal spines in L.stationis where up to three may be found although they were
completely absent from his African specimens. L. xinanensis shows a similar variability in the
development of these spines. L. xinanensis from the lower part of the present section consisted of
many females and rare males neither of which carried dorsal spines. In the middle of the section
specimens with one dorsal spine were found and both males and females were present, whilst in
the upper part of the section many males and females occurred which had three dorsal spines.
De Deckker’s Australian species L.dorsosicula ( Proc . R. Soc. Viet., 93, 43-45, figs. 1, 2a-i,
1981) has between three and six spines dorsally and also differs in its much reduced turberculation.
Comparisons with other species are not close. i
Limnocythere xinanensis has been found in the Guizhou Yunnan Province in China in deposits
ranging from Pleistocene to Recent in age.

margins of the valves in dorsal view (PI. 14, 132, fig. 2: PI. 14, 134, fig. 2). Each valve develops five
tubercles anteriorly and four or five posteriorly. These are constant in position and there is no
difference between the sexes. Hinge merodont, right valve with a long, smooth anterior
toothplate, a shorter, thicker, smooth posterior toothplate and slightly sinuous interconnecting
groove. Right valve free margin with strong selvage and posteroventrally the valve bulges down
well below the valve margin. Typical cytheracean muscle scar pattern with a row of four adductor
scars, the outer two oval, the central two very elongated. Two small, rounded mandibular scars
occur anteroventrally.
This species is very similar to Metacypris changzhouensis Chen ( Acta Palaeon. Sinica, 13(1), 7, pi.
2, figs. 9, 13, 1965) but in the latter the tubercles lack the constancy and regular distribution seen in
M. aphthosa. M. changzhouensis differs further in that the right valve is larger than the left valve,
and in addition it is also a bigger species (length 680/xm). Differences are also apparent in dorsal
view when the posterior part of the carapace is compared. It also differs from Metacypris unibulla
Hou & Chen (Acta Palaeon. Sinica, 13(1), p. 9, pi. 1, figs. 5, 9 1965) because the latter only has
one posterior tubercle, is thinner in dorsal view and differs in size amongst other things. The
present species differs from Metacypris cordata Brady & Roberston (Brady and Roberston, Ann.
Mag. nat. Hist., Ser. 4. 6, 19-20, pi. VI, figs. 1, 9, 1870; Pinto & Sanguinetti, Esc. Geol. P. Alegre,
4, pi. II, figs. 1 a-e, 1962; Colin & Danielopol, Palaebiologie Continetale, XI, 1, 29-30, pi. 14, figs.
5-9, 1980), in that in the latter the right valve is the larger, there is no surface tuberculation and it
is longer and narrower than Metacypris aphthosa which is a short and very inflated species.
Males, females and younger instars are all found together in the deposits examined
although the females are more than twice as abundant as the males and instars together.
M. aphthosa has so far only been found in Pleistocene deposits in Guizhou Province, SW China.

Remarks:
Genus BENINEA gen. nov.
Type-species: Beninea ibecetenensis sp. nov.
from Benin, W Africa.
Cytheridae essentially characterized by its hinge. Right valve: anterior element consisting of a
strong, rounded tooth, a long crenulate groove and a posterior plate-like cardinal element bearing
five strong crenulations; left valve: large anterior socket, long crenulate ridge slightly arched and a
posterior strongly crenulate socket. No accommodation groove.
Carapace subovoid in side view, elongate ovate dorsally. Anterior margin broadly rounded,
posterior margin obliquely rounded. Left valve larger than right; dorsal margin regularly arched,
with greatest height in middle part. Anterior margin of right valve more angular. Surface smooth
with well developed normal sieve-type pore-canals. Eye tubercle absent. Sexual dimorphism
pronounced; males more elongate than females.
Central muscle scars: vertical row of four coalescent rounded scars and two equally rounded
scars in front (Text-fig. 1).
Narrow marginal zone; line of concrescence coincides with the inner margin. Radial pores
straight, simple and up to eight on anterior margin (Text-fig. 1).
Externally, Beninea is comparable to Bopaina Apostolescu, 1961 and “Clithrocytheridea" senegali
Apostolescu, 1961 from the Senonian of Senegal (Rev. Inst, franq Petrole, 16, (7-8), 779-867).
Except for the absence of an accommodation groove and the median ridge on the left valve, the
hinge of Beninea is close to Apatocythere Triebel, 1940 ( Senckenbergiana , 22, (3/4), 160-227),

ON GLYPTOLICHVINELLA SPIRALIS (JONES & KIRKBY)
by Robert F. Lundin
(Arizona State University, Tempe, U.S.A.)
Genus GLYPTOLICHVINELLA Pozner, 1966
Type-species (by original designation): Kirkbya spiralis Jones & Kirkby, 1884
Diagnosis: Cytherellacean genus the lateral surfaces of which are ornamented with two ridges, one which is
subparallel to the lateral outline and may or may not continue to form a marginal ridge, and
another which is median and bends below the adductorial sulcus. Straguloid process variably
developed. Domatium with variable number of separate egg compartments.
Remarks: The earliest valid publication of this genus known to me is that of K. Ya. Gurevich (in Fossil
Ostracoda, O. S. Vyalov, ed., Acad. Sci. Ukr. SSR, Inst. Geol. & Geochem. Fossil Fuels, 1966 =
Israel Program for Scientific Translations, 1971 English translation of Russian original). In that
publication, Pozner is credited with authorship of the genus and the generic name is spelled
Glyptolichvinella rather than Glyptolichwinella as it appears in various other literature.
Accordingly, the former spelling is used here.
Lichvinella scopinensis Pozner (op. cit.) is the type-species for Lichvinella. M. N. Gramm
(Vladivostok) has provided me with two photographs of L. scopinensis, one of which shows that
the females of that species have egg compartments and a limen. The discovery of egg
compartments in Glyptolichvinella indicates, therefore, that this genus differs from Lichvinella
only by the presence of a separate longitudinal ridge on the lateral surface of each valve. I judge
this to be only a species-level difference but do not formally synonymize the two genera until more
and better material of each can be studied.

the species, it is premature to designate a neotype.

Linn (Lower Asbian, Dinantian), Lewisburn, North Tyne, Northumberland, England; approx,
lat. 55° 10'N, long. 2° 20'W. Specimens I 1719 are from Lower Carboniferous (Dinantian)
“Calcareous Sandstone Series, at Linnhouse Water, Linlithgowshire”, Scotland; approx, lat. 56°
N, long. 3° 40' W. I 1719 contains six carapaces (two figured herein).
Glyptolichvinella species with spiral ridge along entire margin which at midlength of dorsum runs
anteroventrally and then parallels anterior, ventral, posterior and posterodorsal margins,
terminating just behind the adductorial sulcus. Separate longitudinal ridge on lateral surface bends
below adductorial sulcus. Anterior straguloid process weak. Adult females with five (perhaps
more or less) oval to circular egg compartments in each valve. Surface granulose.
Along with the report of Lundin & Visintainer (Stereo-Atlas Ostracod Shells, 14 (33), 143-148,
1987) on G. ovicella, this is the first report of egg compartments in the domatium of females of this
genus. Only 7 specimens (carapaces) of G. spiralis have been available to me. All are damaged and
the 3 illustrated here provide impressions of the species only in the lateral views shown.
Known from Lower Carboniferous (Visean) of Scotland and England (see Robinson, 1978, op.
cit.) Reported also from the Lower Carboniferous of the USSR (see Gurevich, 1966, op. cit.).

Stereo-Atlas of Ostracod Shells 14, 145 Glyptolichvinella ovicella (3 of 6)
Remarks: Glyptolichvinella ovicella is readily distinguished from G. spiralis (= Kirkbya spiralis Jones &
Kirkby, 1884; see Jones & Kirkby, Ann. Mag. nat. Hist., 5, 15, 184, 1885) by differences in the
lateral ridges, and from G. nodosovidera Crasquin, 1983 (see Crasquin, Ann Soc. Geol. Nord. CI1,
191-204, 1983) by differences in the lateral ridges and by the absence of eye tubercles.
This is the first report of separate compartments to house eggs for this genus. Lundin (see
Stereo-Atlas of Ostracod Shells, 14 (32), 139-142, 1987) reports similar egg compartments in the
type-species, G. spiralis (Jones & Kirkby, 1884) and we conclude, therefore, that this is a generic
character which needs to be verified in other species of the genus. The number of egg
compartments per valve varies from three to six and no carapace studied has more than eleven or
fewer than six. Normally the number of egg compartments in each valve of a carapace is equal, but
in some cases the right valve has one more compartment than the left valve. There is no systematic
change in the number of egg compartments per specimen through the 1810m-interval from which
the studied specimens were derived.
Except for one adult tecnomorphic left valve and one juvenile tecnomorphic right valve, all
specimens studied are complete carapaces. We cannot, therefore, definitively demonstrate the
existence of a limen in the females. An exterior depression at the anteroventral edge of the
domatium suggests a limen is present. The presence of a well-developed anterior straguloid
process and the morphology of the contact margin and hinge of the two isolated valves available
for study further indicate that Glyptolichvinella is a typical platycope ostracode.

Distribution: Known only from the type locality. The stratigraphic interval containing this species is certainly, in
part (if not entirely), late Devonian (Frasnian and/or Famennian) but it possibly ranges into the
early Carboniferous.
