Stereo-Atlas of Ostracod Shells 7, 3 Eographiodactylus sulcatus (3 of 8)
Diagnosis: Up to 0.69mm long (without spine). Sulcus distinct. Velum-like structure reaching dorsal border anteriorly, diverges away from free margin in posterior direction, terminating in a postero ventral spine. Marginal ridge very faint. Lateral surface smooth except for some fine pores or pustulae; velum-like structure radially striated in anterior regions, spur-like part has hollow tubules.
Remarks: The type-species, Eographiodactylus eos Kraft (Mem. geol. Soc. Am., 86, 62, 1962), lacks a well developed sulcus but has a faint depression dorsal of, and slightly anterior to, valve centre and an internal muscle attachment ridge (sulcament) marking the position of the external depressed area. Furthermore, the adventral structure in if. eos terminates in the anterocentral region, where it forms a second spine-like process.
Eographiodactylus hyatti Copeland (Geol. Surv. Can. Pap., 72 (43), 24, 1973) is distinguished mainly by its reticulate shell. Its adventral structure does not form a spur or spine anteriorly and runs parallel to free margin throughout its length, S2 is developed only as a shallow depression, and the marginal ridge is relatively strong. In Eographiodactylus billingsi Copeland (Bull. geol. Surv. Can., 187, 19, 1970) the main adventral structure also runs more or less parallel to the ventral free margin; posteroventrally it supports a small spine, anteriorly it does not form a cusp or spine. Its marginal ridge is very distinct and is larger in the right valve. E. sulcatus is the only species of the genus known from Europe. E. eos occurs in the Middle Ordovician of the U.S.A., E. hyatti and E. billingsi in the Upper Ordovician of Canada.
The main adventral structure of Eographiodactylus was called a “velate frill” by Kraft (op cit., 63). Copeland (1973, 25) also considered this structure to be a velate ridge whereas Schallreuter (op. cit., 280) questioned its velar nature. The structure in question cannot, however, be considered a marginal sculpture: in E. sulcatus it diverges from the free margin and normally a marginal sculpture runs parallel beside or at the free margin. Kraft (op. cit.) does not mention a marginal sculpture in the type species, whereas in E. sulcatus there is a very faint marginal ridge (PL 7, 8, fig. 4), and in if. hyatti and especially in E. billingsi it is very distinct. It could be, therefore, that the main adventral sculpture of Eographiodactylus is a velum but at present it is difficult to decide whether it is homologous with the palaeocope velum. In the Quasillitinae, Adamczak (Senckenberg. leth., 57 (4/6), 360, 1976) calls the feature a marginal ridge;how- ever, if this ridge is homologous with the main adventral structure (velum?) of Eographiodactylus, his terminology would be incorrect.

Eographiodactylus sulcatus ( 2 of 8)
Stereo-Atlas of Ostracod Shells 7, 5 Eographiodactylus sulcatus (5 of 8)
Remarks: Kraft {op. cit., 62) tentatively placed Eographiodactylus in the questionable family Quasillitidae. He also (cont’d.) noted that the genus Graphiadactyllis Roth, 1929 is similar and that “there is little doubt that Eographiodactylus is the root stock from which Graphiadactyllis and the closely related Quasillites developed”. Kellett ( Micropalaeontology , 9 (2), 229, 1963) also thought Eographiodactylus “a distinctive, truly quasillitid-graphiadactyllid ostracod, ancenstral to a group common in the Middle Devonian”. Adamczak {op. cit., 359 - 361) considered the latter ostracod group as a subfamily of the Thlipsuridae, Thlipsuracea, suborder Metacopa, but he did not mention Eographiodactylus as a member of the Quasillitinae.
The familial assignment of Eographiodactylus is difficult to decide at present. Perhaps the genus represents a separate family or subfamily. Its relationship to the Quasillitinae is expressed mainly by the form of the main adventral structure. The type-species, Quasillites, for example, also possesses at the anterior border a cusp or frill, or both, and also a large posteroventral spine (Peterson,/. Paleont., 38 (5), 846, 847, 1964), but the spine is not a part of the main adventral structure as in Eographiodactylus (Kesling et al., Contr. Mus. Paleont. Univ. Mich., 15 (2), pi. 2, fig. 2, 1959). Similarity also exists in minor features such as reticulation (cf. Peterson, op. cit., pi. 135, figs. 8, 9 and Copeland, op. cit., pi. 4, figs. 18, 19). In its velum-like adventral structure Eographiodactylus also resembles Leptoprimitia Kummerow, 1953 and Zeuschnerina Adamczak, 1976, both (Adamczak op. cit., 379) externally well differentiated ropolenellids which have “evolved presumably from Ropolonellus-]ike forms by developing a velum- like marginal structure. . .”

Eographiodactylus sulcatus (7 of 8)
Remarks: The hinge in Eographiodactylus is long, straight and undivided whereas in typical Quasillitinae it is (cont’d.) shorter, convex and tripartite (for example, see Adamczak, op. cit., text-fig. 42, pi. 20, fig. 127a).
According to Kellett (op. cit.) “This is not surprising, as a shortening of the hinge is an evolutionary trend characteristic of the Ostracoda”. This trend also occurs, for example, in the Kloedenellacea (Guber & Jaanusson, Bull. geol. Instn. Univ. Upsala, 42, 2, 1965 - Publ. Palaeont. Instn. Univ. Upsala, 53, 4, 1964); it is long and straight in the Ordovician monotiopleurids, short and convex in the younger kloedenellids (op. cit., text -figs. 2C-F).
The Metacopa are defined by Adamczak (op. cit., 358) as “medium sized podocopids without duplicature”. According to Kraft (op. cit., 62) Eographiodactylus lacks the (narrow) inner lamella noted (Swain, J. Paleo, 27 (2), 270, 1953) in Graphiadactyllus. E. sulcatus has a small, entirely fused inner lamella (PL 7, 6, fig. 2). Perhaps this is also, like the long straight hinge-line, a primitive feature. In the Bairdiocyprididae — considered (Adamczak op. cit., 319) to be a very simple group of podocopes and possible ancestors of the Metacopa — a thin inner lamella is also present (Adamczak, op. cit., pi. 1, fig. If).
A special feature of Eographiodactylus is the R/LV-overlap. Both, E. eos and/1, sulcatus have a contact-groove in the right valve to receive the overlapped margin of the left valve (Kraft, op. cit., 63, pi. 16, fig. 7a; herein PL 7, 6, fig. 1). In the Quasillitinae and the Ropolonellidae the left valve is larger. Also in many other Ordovician Metacopa with two stop-pegs the left valve is the larger valve.
Distribution: Ojlemyrflint erratic boulders of the Isle of Gotland (Baltic Sea) and of the Kaolinsand (Pliocene-Pleistocene) of the Isle of Sylt (N Sea); Upper Ordovician.

ON KLIMPHORES PLANUS SCHALLREUTER
by Roger E. L. Schallreuter (University of Hamburg, German Federal Republic)
Genus KLIMPHORES Schallreuter, 1966 Type-species (by original designation): Klimphores planus Schallreuter, 1966
Diagnosis: Small (normally <lmm long) palaeocopes, more or less amplete. Pair of convex, oblong nodes occur offset towards anterior end, mainly in dorsal half of valve; anterior node extended, lobe-like anteroventrally; preadductorial node totally or almost totally incorporated in anterior node. Border between lateral and marginal surface (pseudovelum) forms simple and sometimes prominent bend, ridge- like keel or bend with row of spines. Lateral surface, including nodes, may be punctate or reticulate; base of lumina may have sieve-pores.

Stereo-Atlas of Ostracod Shells 7,11 Klimphores planus (3 of 8)
Remarks: Klimphores is type-genus of the Binodicopa (Binodicopina). For a list of congeneric species see Schallreuter [Ber. dt. Ges. geol. wiss. (A), 11 (3), 394, 1966; Ibid., 14 (2), 199 - 209, 1969], Kniipfer [Freiberger ForschHft. ser. C, 234 (Zur Palaontologie und Biostratigraphie des Palaozoikums und Mesozoikums Europas, 3), 6, 1968] and Gailite [Palaeontologija i stratigrafija Pribaltiki i Belorussii (Palaeontology and Stratigraphy of the Baltic and Byelorussia) 3, 399 - 44, 1971]. Klimphores ansiensis Gailfte and K. bimembris Gailite (op. cit .) belong to Laterophores Schallreuter, 1968 (Ber. dt. Ges. geol. wiss., 13 (2), 248), a genus very similar to, and presumably ancestor of Klimphores.
Sieve-pores in Palaeozoic ostracods were first described by Gramm (Palaeont. z, 151 - 54, 1977), from a Lower Carboniferous Editia species. Sieve-pores in Ordovician ostracods were first figured by Schallreuter (Stereo-Atlas of Ostracod Shells, 4 (1), 9 - 16, 1977), in Miehlkella cribroporata Schallreuter. In the latter the sieve-pores consist of rings of pores, whereas in Klimphores planus they form fields of many irregularly arranged pores.

ON FORAMENELLA PARKIS (NECKAJA)
by Roger E. L. Schallreuter (University of Hamburg, German Federal Republic)
Genus FORAMENELLA Stumbur, 1956 Type-species (by original designation): Euprimitia parkis Neckaja, 1952
Diagnosis: A genus of Perspicillinae ; unisulcate, sulcus deep but narrow; no special lobal features; no distinct adventral sculptures except for the 5 loculi in the female valve.
Remarks: Stumbur (Tartu Riikliku Ulik. Toim., 42, 187, 1956) designated Euprimitia parkis Neckaja as the type-species of Foramenella. Because Sarv ( Eesti NSV Tead. Akad. Geol. Inst, uurimused, 4, 154, 1959) considered that F. parkis of Stumbur was not conspecific with Neckaja’s species he introduced the new species ‘Foramenella porkuniensis nom. nov.’ for Stumbur’s material although the term ‘nomen novum’ was in error. If Sarv is correct in regarding Stumbur’s material distinct from E. parkis Neckaja then we have a “Misidentified type-species” (ICZN article 70a) and a case for the commission. It is not certain, however, that F. porkuniensis represents a separate species (see below); Stumbur was probably correct and F. porkuniensis should therefore be regarded as a junior subjective synonym. Foramenella ? phippsi Copeland (Geol. Surv. Can. Pap., 72 (43), 14, 1973) differs so strongly from F. parkis and F. porkuniensis that its assignment to the genus is very doubtful and is not considered in the diagnosis.

Diagnosis: As for the genus
Remarks: According to Sarv (op. cit. 1 19, 1962) Foramenella porkuniensis is distinguished from F. parkis by its strongly convex valves, its narrow, deep S2, and in having relatively well separated loculi. The new material (herein) shows variation in length (9 valves = 0.83 — 0.95mm; holotype of F. parkis = 0.80mm, that of F. porkuniensis = 0.97mm) and surface ornamentation [nearly smooth, as recorded from F. porkuniensis (Sarv, op. cit. 119, 1962) or reticulo-granulated, as recorded from F. parkis (Neckaja, op. c/r.)] .
Distribution: Recorded from the Rakvere Stage (E) and lower part of the Nabala and Vormsi stages (Fj a + b) of Latvia (Gallite 1972), the Lyckholm (Saaremyjza) Beds (F^ of Lithuania (Neckaja 1952) and the Pirgu Stage (F]C) of Estonia (Sarv 1959). The conspecific F. porkuniensis is known only from the Porkuni Stage (F2) of Estonia (Sarv 1962).
Recorded herein from the Ojlemyrflint erratic boulders of the Isle of the Gotland (Baltic Sea) and the Kaolinsand Pliocene-Pleistocene) of the Isle of Sylt (N Frisian Is., N Sea).

Stereo-Atlas of Ostracod Shells 7, 23 Disulcina syltensis (3 of 4)
Diagnosis: Adult 9 0.45 - 0.54mm long. Sulcus (S2) developed as a cavum, external slit of which is bow-like, parallel to ventral margin, and slightly constricted anteriorly by small rounded projection. Posteroventral lobe indistinct, expressed only by short spine in posteroventral region slightly above end of velum.
Remarks: In Disulcina interminata Sarv (Eesti NSV Tead. Akad. Geol. Inst, uurimused, 4, 146, 1959) the cavum is more steeply inclined to the hinge-line and the edge of its slit-like opening bears short spines. The termination of the posteroventral lobe is similar in both D. syltensis and D. intermedia but in the latter the velum passes around the end of the posteroventral lobe forming a fissum behind the lobe. A second fissum may occur anteroventrally of S2.
In the type-species of Disulcina Sarv, 1959, D. perita (Sarv, Ibid., 1, 37, 1956), the slit of the cavum is even more steeply inclined to the hinge-line and apparently longer (Sarv op. cit., 1959, pi. 26, figs. 6 - 9). Furthermore, this species possesses a long, distinct furrow (not sulcus!) behind the postero- ventral lobe.
PL 7, 24, fig. 2 shows faint hemispherical depressions in the admarginal ‘botulate’ antrum, evidently representing orimentary loculi; similar structures are found in Triemilomatella prisca Jaanusson & Martinsson from the Silurian of Gotland (Bull. geol. Instn. Univ. Upsala, 36 (4) = Pub I. Palaeont. Inst. Univ. Upsala, 13, 1956). The new species is an example of a transition stage between a botulate and a loculate antrum. It is a further proof that the practice of separating higher family units using only the loculate or botulate nature of the antral dimorphism is ill-advised (cf. Henningsmoen, Geol. For. Stockh. Fork., 86 (4), (for 1964), 386, 1965, Schallreuter,- Geologie, 15 (7), 846, 1966 and Revta esp. Micropaleont., 6 (2), 163, 1974).

Remarks: This species is easily recognised by the posteroventral lobe or lappet in the presumed male seen in side view. In this it differs from S. rhomboidalis (which occurs over the same range) and also in the more strongly pitted surface. Presumed females of S. bilobata are more oval than their S. rhomboidalis counterparts. S. bilobata is well known from the Upper Hauterivian and Barremian of N Germany and N England where associates include Acrocythere hauteriviana, Apatocythere ellipsoidea, A. simulans, Eucytherura nuda, Protocythere hechti and P. triplicata. It has also been recorded from the Barremian of N0vling No. 1 well in Central Jutland, Denmark by O. B. Christensen {Geol. Surv. Denmark III Series, 40, 115, 1973).

Paranotacythere speetonensis (3 of 4)
Diagnosis: In side view oblong with slightly concave dorsal margin sub-parallel to ventral margin. Costate and tuberculate ornamentation, the six most prominent tubercles forming a triangle behind the median sulcus and an inverted triangle in front of it. A ventral ridge links the lower three tubercles. Sexual dimorphism very marked, the presumed males much lower in proportion to the length than the presumed females.
Remarks: The adult hinge is antimerodont and the very prominent eye tubercle lies immediately above the most anterodorsal of the six main tubercles. Earlier instars are more triangular in side view with a convex dorsal margin. In the earlier stages reticulation is more in evidence than tuberculation and Instar 7 (PI. 7, 36, fig. 1) has a prominent posteroventral spine which is not seen in the later stages. J. Rey et al (C. R. Somm. Seances Soc. Geol. France ,5, 153, 1968) and M. M. Ramalho & J. Rey ( Bolm . Soc. geol. Port., 17, 33, 1969) note, but do not figure, Orthonotacythere cf speetonensis in beds regarded as largely Berriasian in age in the Cretaceous Basin of Portugal.
Distribution: P. speetonensis is very common in the Blue Red (D6) at Speeton where it occurs associated with Schuleridea juddi Neale, Mandelstamia sexti Neale, Paracypris caerulea Neale and Galliaecytheridea teres (Neale). Tire beds are typically lithified, fine-grained, calcareous muds and all these species have not been found outside rocks of Berriasian age.

Diagnosis: Carapace smooth and hairy, epecially in ventral area which is very broad and almost flat; shell thick;
selvage further away from edge of shell in posteroventral area in both valves and closest anteriorly in LV. Hinge line, when viewed dorsally, straight except at both extremities where LV overlaps RV. Natatory setae of antenna reduced; 1st thoracic appendage with single terminal claw and long, thick terminal bristle; furca strong with broad and short claws (coarsely denticulated), thin and pilose anterior bristle, posterior bristle broader, pilose and as long as claws. Furcal shaft with 5 rows of thick spinules.
Remarks: Scottia audax was originally described by M. A. Chapman (1961) as a species of Mesocypris. It is considered, however, that the resemblance of this species to Scottia pseudobrowniana Kempf, [Eiszeitalter u. Gegenwart, 22, 43 - 46, 1971] necessitates a change at the generic level: the shell morphologies and appendages being very alike. The most diagnostic similarity is the presence of a long and thick distal bristle on the 1st thoracic appendage that is almost as long as the distal claw. In Mesocypris, on the contrary, this bristle is thin and small. For the same reason, Scottia insularis Chapman [Hydrobiologia, 22, 1 - 40, 1963] should be transferred to Mesocypris asM insularis because of the short and thin bristle on the 1st thoracic appendage.

Scottia audax (5 of 8)
LJ.,
Remarks: Scottia audax, of which no male has so far been described, differs from S. pseudobrowniana on the (contd.) following details: a slight rib, running parallel to the hinge is present on the shell in the dorsal area of S. pseudobrowniana; best seen when the shell is viewed from the anterior — this ridge is absent in S. audax. Also in S. pseudobrowniana, the overlap of LV over RV, just in the area anterior to the hinge, is triangular in shape and forms a small lump. This feature was seen on the holotype (Brit. Mus. (Nat. Hist.) no. (1900.3.6.35A) designated by Kempf (1971) and on specimens found in Sars’ collection (Oslo Museum) donated by Norman and collected in Dec. 1886 from the type locality — this feature is absent in S. audax. An extremely long and thick bristle, plumose at its end, is attached on the inner side of the inner masticatory process of the maxilla of S. pseudobrowniana whereas it has not been seen in S. audax. The denticulation of the furcal claws differs in both species: in S. pseudobrowniana, the short denticles are present along the middle third of the length of the claw whereas in S. audax they are long and almost indistinguishable from the other denticles in the distal third of the claw, in the former species they are longer and finer.

L. Danielopol & E. E. Vespremeanu ( Fragmenta Balcanica Mus. Maced. Sc. Nat., 5, 135 - 146, 1964) and Bronstein, Z. S. (Faune de L’URSS (n.s.), 31, Crustaces 2 (1), 1 - 339, 1947). Note that the species described by the former authors was collected from “the aerial top layer of the floating fen, in the soil and plant detritus” in Roumania. Scottia audax and specimens belonging to Mesocypris collected together, have only been found in leaf litter in Australia.
Scottia and Mesocypris are closely related because their morphologies are alike. They should be included in the subfamily Scottinae Bronstein, 1947 as already suggested by Danielopol in McKenzie (Ann. S. Afr. Mus. 57 (9), 1 57 - 217, 1971) and reaffirmed by De Deckker (VII International Symposium on Ostracodes — ed. Serbain Geological Society, 9 - 17, 1979). Psychrodromus Danielopol & McKenzie 1977 is also closely related to Mesocypris and therefore should be included in this subfamily.
Distribution: S. audax has so far been found in New Zealand and eastern Australia.

ON CALLISTOCYTHERE LITTORALIS (MULLER)
by John Athersuch and John E. Whittaker (B. P. Research Centre, Sunbury and British Museum (Natural History), London)
Genus CALLISTOCYTHERE Ruggieri, 1953 Type species: Cy there littoralis Muller, 1894
1958 Cry ptocy there, M.I. Mandelstam, Trudy vses. neft. naucho-issled. geol.-razv. Inst. (Microfauna SSSR), 9, 280.
Diagnosis: Carapace elongate, subquadrangular; surface ornament undulating and anastomising ridges. Anterior hinge element of left valve with two or more distinct teeth. Vestibule poorly developed or absent.
Remarks: Callistocythere is less elongate, more heavily ornamented and has a thicker shell than Leptocy there. The hinge of the former genus is more robust, the anterior hinge element being divided into two to four individual toothlets while Leptocy there has only a single tooth. Moreover, an anterior vestibule is well developed in Leptocythere, but poorly developed or absent in Callistocythere. The appendages of these two genera are not noticeably different.

Stereo-Atlas of Ostracod Shells 7, 66
Callistocy there littoralis (6 of 6)
Diagnosis: Small (0.40 — 0.45mm long); prominent posterior ridge running sub-parallel to margin; central area of valves with broad anastomosing, pitted ridges; pits preferentially formed where ridges terminate or coalesce; anteriorly, a ridge, continuous with the eye tubercle, runs obliquely forward to the anteroventral margin; behind this ridge lie two large elongate fossae; mid-dorsolaterally a prominent, short, vertical ridge is separated from the central area by a U-shaped sulcus.
Remarks: C. littoralis was first described by Miiller, 1894 from the Bay of Naples, but unfortunately his specimens no longer exist (Athersuch, Pubbl. Staz. zool. Napoli, 40, 344 - 348, 1978). In order to establish the true identity of this species, we have chosen a neotype from the type locality which fits best in size and ornament Muller’s original description and illustration. In Britain, C. littoralis has frequently been misidentified as C. crispata (Brady, 1868), and was thought by Brady and Robertson, 1869, Brady, Crosskey and Robertson, 1874 and Brady and Norman, 1889 to be merely a small northern variety of the latter species.
There is considerable variation in the degree of foveolation of the ridges, the British specimens having the most subdued secondary ornament.
Since no males appear ever to have been found, C. littoralis is believed to reproduce by parthenogenesis.
Distribution: Recent; Britain (J. E. W. collection); Ireland (Brady and Norman, op. cit .); Norway (Sars, op. cit.)', Atlantic coast of France (Yassini, op. cit.)-, Tenedos and Bay of Naples (herein). A phytal species found frequently in the littoral and sublittoral zones.

Callistocy there crispata (5 of 6)
Diagnosis: Large (about 0.56mm long); carapace with prominent anastomosing, rugose ridges; one is continuous with the eye tubercle and runs obliquely forward to the anteroventral margin; behind this ridge lie two large, elongate fossae; two lateral ridges run back from below the eye tubercle and bifurcate posteriorly; the dorsolateral ridge is straight, having a U-shaped swelling anteriorly and its posterior branches swollen terminally; the ventrolateral ridge is depressed medially, its posterior branches terminating in strong ridges, each bearing an irregular tubercle.
Remarks: Brady’s syntypic specimens of Cythere crispata from Tenedos could not be found in either the Brit. Mus.
(Nat. Hist.) or the Hancock Museum, Newcastle-upon-Tyne, and are presumed lost. However, a bottle of residue from the type locality was found in the Brit. Mus. (Nat. Hist.), in the collection of Brady’s brother, H. B. Brady, and this yielded several species of Callistocythere. The neotype (PI. 7, 68, fig. 1) was selected from the only one of these species which conforms to the original illustration and description. In particular, the attitude of the ridges in lateral view, and the dorsal aspect of the carapace match extremely well. Furthermore, it is the only species in the Tenedos sample which fits the dimensions given by Brady (length v4S inch = 560 /zm), the others being considerably smaller.
The fact that no males of C. crispata are known suggests that this species reproduces by parthenogenesis.

A stratigraphical index of British Ostracoda
The first of a series of Occasional Papers of the British Micropalaeontological Society. ISBN 0 902354 08 6
Edited by Raymond H. Bate and Eric Robinson
Geological Journal Special Issue No. 8
Developed from ostracod specialist meetings of the British Micropalaeontological Society this book aims to illustrate the stratigraphically important index ostracods of Britain. Brief descriptions of the ostracods, together with palaeogeographic maps, range tables, discussions on present knowledge and on faunal associations make this a valuable book for both student and professional micropalaeontologist. Introductory chapters on the biography of past ostracod workers and on ostracod morphology add to the book's value as a reference work. 500 pp
