Stereo-Atlas of Ostracod Shells 17, 79 Gammacythere klingleri (3 of 4)

Diagnosis:

Remarks:

Distribution:

A species of Gammacythere with a distinct posteroventral swelling. Ornament coarse, consisting of

irregular pitting and ribbing with little or no alignment. Dimorphic. Carapace elongate-ovate,

more so in males, dorsal margin straight in RV and sinuous in LV. Ventral margin sinuous with

concavity in front of mid-length. Anterior and posterior margins laterally compressed, the former

broadly rounded and the latter acuminate. Greatest height at anterior cardinal angle; greatest

length running obliquely from posterior extremity to a point below mid-height on anterior margin;

greatest width behind mid-length. Ventro-lateral margin strongly inflated, especially posteriorly.

Lateral ornament coarse in the mid-valve region, becoming much weaker marginally. Dorso-

median sulcus present. Internal details and marginal structures as for genus.

Kinkelinella foveolata Michelsen (Danm. Geol. Unders., 104, 189, 1975), considered here to

belong to the genus Gammacythere , is similar in size but differs from G. klingleri in that it lacks the

posteroventral swelling. G. ubiquita Malz & Lord ( Senckenberg . leth ., 57, 252, pi. 1, figs. 1-6, pi.

2, figs. 7-19, 1976), the type species, is larger (9 carapace 530-810 /urn long, cf 700-900 /urn long)

and more weakly ornamented than G. klingleri. Malz & Lord (op. cit., 256) consider Ostracode E

of Apostolescu (Revue Inst. fr. Petrole , 14, 817, 1959) also belongs to this genus.

Early Pliensbachian, Lower Jurassic; jamesoni - lower ibex zones of Hamburen WA 2 borehole,

N. Germany (Klingler, op. cit., 1962) and upper jamesoni - ibex zones of the Dorset coast

(herein). The stratigraphic range of G. klingleri overlaps with that of G. foveolata (Michelsen) in

the upper jamesoni Zone, and with G. ubiquita Malz & Lord in the upper ibex Zone.

ON BOLBINELLA CUMULATA KANYGIN

by Roger E. L. Schallreuter & Aleksandr V. Kanygin

(University of Hamburg, Germany & USSR Academy of Sciences, Siberian Branch, Novosibirsk)

Genus BOLBINELLA Kanygin, 1967

Type-species (by original designation): Bolbinella cumulata Kanygin, 1967

Diagnosis: Median-sized to large Nodambichilinae (Tvaerenellidae, Hollinacea). Lobes appear as two broad

rounded or dorsally conical bulbs, one on each side of deep, funnel-sulcus. At the posterior base

of the anterior lobe a weak preadductorial node may occur. Lobes joined ventrally by a more or

less distinct connecting (‘zygal’) lobe. Velum appears ventrally as a thick keel (tecnomorphs) or

broad flange (females), presumably forming a long dolonal antrum; laterovelar furrow

correspondingly shallower in females. Marginal sculpture: a row of spines. Surface smooth,

punctate or reticulate.

Remarks: In spite of the fact that Bolbinella was named by Kanygin ( Ostrakody ordovika gornoj sistemy

Cherskogo , 100, 1967), because of its similarity to Bolbina the genus was originally placed within

the Billinae ( recte Bolliinae). The antral dimorphism demonstrated herein in the type-species of

Bolbinella indicates that the genus is probably related to the tvaerenellid genus Bolbina and

therefore to the subfamily Nodambichilinae Schallreuter, 1967 (Geologie, 16, 931). This subfamily

is characterized by two lobes (spines, bulbs) at the dorsal margin and is known from both N.

America and Baltoscandia.

Kanygin, 1977, op. cit . ; long. 171° 17' E, lat. 66°35'N). All specimens occur on rock pieces.

Species of Bolbinella with length up to 2.34 mm. Dorsal lobes more or less conical. Relatively

distinct preadductorial node. Connecting lobal (‘zygal’) sculpture flat and relatively indistinct. A

small, flat node-like sculpture in anterodorsal corner field. Punctate to reticulate.

The older (lower Ordovician) B. lecta Kanygin, 1967 (op. cit., 122) is smaller (c. 1.8mm long), the

lobes are more rounded and the preadductorial node is very weak or missing. Furthermore, its

connecting lobe is more distinct and its surface is smooth.

Known only from Siberia: from the type locality and also from the Chukotka Peninsula

(Issehtehnskian Formation), from Sette-Daban (Labystanskian Formation) and from the

Kulyumbeh river in the Siberian platform (Bodenia aspera Zone). All middle Ordovician (for

details see papers by Kanygin in synonomy list).

ON CHEGETELLA CHEGITUNICA KANYGIN

by Ingelore C. U. Hinz, Aleksandr V. Kanygin & Roger E.L. Schallreuter

(University of Bonn, Germany , & USSR Academy of Sciences, Siberian Branch,

Novosibirsk & University of Hamburg, Germany)

Genus CHEGETELLA Kanygin, 1977

Type-species (by original designation): Chegetella chegitunica Kanygin, 1977

Diagnosis: Large bradoriid; postplete with retral swing. Hinge-line straight. A more or less distinct sulcal depression may

occur in mid-dorsal region dorsal of base of spine. Long, posteriorly curved spine in midventral posterior

region, interrupting sharp ridge which starts and terminates in the cardinal corner fields and in lateral view

approximately parallels lateral border anteriorly and diverges from the free margin posteriorly; anteriorly in

ventral view it diverges gradually from the free margin. A second, keel-like, marginal ridge occurs parallel to

free margin. Area between ridges is steeper anteroventrally than posteroventrally. Surface finely and sparsely

punctate.

Remarks: Chegetella was originally was placed within the Aparchitacea, suborder Leperditiida (Kanygin 1977, 73).

However after seeing the original material, Schallreuter considered that Chegetella is a bradoriid. This idea

was also acknowledged by Hinz, also after investigation of the type-material. Its bradoriid features include:

its relatively large size; its retral swing; and, instead of a proper sulcation and lobation (except spine), the

occurrence and form of its lateral ridge; as well as the apparently very thin, black shell.

Lateral and marginal ridges in bradoriids are known; for example from Ophiosema Opik, 1968 ( Bull. Bur.

Miner. Resour. Geol. Geophys. Aust., 103, pi. 3, figs. 1-2) and Auriculatella Tan, 1980 (see S. Huo, & D. Shu,

Cambrian Bradoriida of South China, Beijing, pi. 24, 1985). Ventral spines have been described from the

bradoriid Spinokunmingella Huo & Shu, 1985 (op. cit., text-figs. 8-30. 31, pi. 13, figs. 1-10). The ‘knotty’

surface of the figured steinkern of Chegetella (PL 17, 88, fig. 3) may indicate an original adornment by minute

spines similar to the long dorsal spines of Monasterium Fleming, 1973 (Pubs. geol. Surv. Qd, 356, Palaeont.

Pap. 31, pi. 4, fig. 5).

Ordovician bradoriids are poorly known. They include Eremos Moberg & Segerberg, 1906 from the

Tremadocian of Sweden (see Treatise on Invertebrate Paleont., part Q, Q102, 1961), Septadella Stubblefield,

1933 ( Q.Jl Geol. Soc. Lond., 89, 371) from the Tremadocian of England, Ludvigsenites Copeland, 1964

(Bull. geol. Surv. Can. 244, 13) from the middle Ordovican of the SW District of MacKenzie, Canada and

Zhexiella, Preaechmina and Polycostalis Shu, 1990 from China (Cambrian and Lower Ordovician Bradoriida

from Zhejiang , Hunan and Shaanxi Provinces, 44, 63). Ludvigsenites is stratigraphically and geographically

the nearest to Chegetella but distinctly differs in many features; however, the size and colour of shell are

similar in both genera.

ON SCANIPISTHIA RECTANGULARIS (TROEDSSON)

by Roger E.L. Schallreuter & Miroslav Kr&ta

(University of Hamburg, Germany & Czechoslovakian Academy of Sciences, Prague)

Genus SCANIPISTHIA gen. nov.

Type-species : Jonesina rectangularis Troedsson, 1918

After Scania, Sweden and because of the possible affinity of the genus to the Lomatopisthiidae.

Gender, feminine.

Small, elongate lomatopisthiid?; rounded-rectangular outline. In front and behind adductorial sulcus

(S2) are two rounded or elongate nodes. Ventrally of the nodes there is an elongate, broad ridge-like

lobal feature parallel to the ventral margin. Parallel to the entire free margin occurs a broad, rounded

ridge-like ‘adventral’ elevation which is separated from the valve lateral surface by a U-shaped furrow.

The typical members of the lomatopisthiids (ostracod suborder uncertain) are characterized by a special

kind of domiciliar dimorphism (lomatopisthiid dimorphism; see A.L. Guber, & V. Jaanusson. Bull,

geol. Instn Univ. Uppsala, 43, 1-19, 1964). Because this type of dimorphism cannot presently be shown

to occur in Scanipisthia, its assignment to the Lomatopisthidae is uncertain. It would represent the

second genus of lomatopisthiids known from Europe, the first being Europisthia Schallreuter (NeuesJb.

Geol. Palaont. Mh., 1978 (3), 175, figs. 1, 2). Europisthia differs most notably in lacking any dorsal

nodes or a lateral lobe-like ridge. The taxon Scanipisthia is formally erected herein; the name previously

featured (as nomina nuda) in faunal logs (see synonymy below).

As for the genus.

Both the Bohemian and the Scandanavian material is preserved in soft shales. In order to study the

external moulds casting with ‘Silcoset’ was used. Troedsson’s original type material consists of three

specimens; from Bohemia five specimens are available. It is, therefore possible that adults are not

represented in the available material.

Stereo- Atlas of Ostracod Shells 17, 95 Pilla latolobata (3 of 4)

Species of Pilla with two broad, elongate (‘lobe-like') nodes, relatively close together; dorsally

rounded. Posterior node more strongly developed, protruding above the straight hinge-line in

lateral view. Lobe-like pseudovelum fused with nodes, gradually becomes confluent with

domicilium posteroventrally of posterior node. Surface finely reticulate to granulose. Valve up

1.10 mm long.

This is the second known species of the genus. The type -species, Pilla piformis Schallreuter &

Siveter, 1988 ( Stereo-Atlas Ostracod Shells 15, 25-28) from the upper Ordovician (upper

Gisbornian or lower Eastonian) of New South Wales, is larger (1.71mm long), and has smaller

nodes which, moreover, are spaced further apart from each other and are equally well-developed

above the hinge-line. Furthermore, in P. piformis the pseudovelum is distinctly separated from the

nodes, and terminates posteriorly more or less abruptly.

In P. latolobata , the post-adductorial node (the dominant node) is in the N3 position, and the

pre-adductorial node is in the N2 position (cf. diagnosis of Pilla of Schallreuter & Siveter, 1988).

Some specimens have a finely reticulate surface; other, more corroded specimens, including those

illustrated herein, are granulose. The size range (0.55 - 1.10 mm long) suggests that four instars are

represented, but the largest may not be the adult stage.

Pilla latolobata occurs in subsurface and other surface samples in the Arenig Series Horn Valley

Siltstone of the Amadeus Basin, Australia. So far it is documented only from the type locality,

where it is associated with conodonts, trilobites, chitinozoans, brachiopods, and nautiloids. Here,

the ostracod assemblage consists of some 150 specimens, virtually all belonging to P. latolobata.

ON NEOEUGLYPHELLA MANDELBAUMAE DEWEY & PUCKETT gen. et sp. nov.

Christopher P. Dewey & T. Mark Puckett

(Mississippi State University & Alabama Geological Survey, U.S.A.

Genus NEOEUGLYPHELLA gen. nov.

Type -species : Neoeuglyphella mandelbaumae sp. nov.

Derivation of name : From the genus Euglyphella Warthin, 1934, plus the prefix neo, inferring new, young, or recent.

Gender, feminine.

Diagnosis: Medium-sized, elongate carapace with left valve larger than right. Papillate ornament over lateral

surface. Anterior and posterior marginal spines present. Hinge merodont. Adductor muscle scar

consisting of about thirty individual spots in compact circular field.

Remarks: Neoeuglyphella possesses the characters of a typical ropolonellid (Quasillitacea) with respect to the

nature of the hinge, the contact margin and the nature of the muscle scar. The (type-) species was first

recognised in the Carboniferous Mississippian of Alabama by Emily Mandelbaum in her unpublished

Master’s Thesis (New York Univ., 143pp., 1970) as a new species questionably referrable to

Euglyphella. Mandelbaum envisaged the species as being the culmination of a trend described by

Peterson ( J . Paleont., 40, 1-20, 1966) in which the loss of carinae in the middle Devonian Euglyphella

compressa lineage, was associated with replacement by papillae. Our material from the Chesterian,

Pride Mountain Formation in Alabama differs, however, from the original definition of the genus

crinoid and fenestrate bryozoan debris and brachiopods.

Elongate carapace with left valve strongly overlapping right. Fusiform in dorsal outline with pinched

ends. Cardinal angles obtuse, rounded. Hinge straight, merodont, with crenulate terminal elements,

inclined posteriorly from point of maximum height at anterior cardinal angle. Irregular papillae over

lateral surface and tiny spines at dorsal and anterior margins on both valves. Adductor muscle scar

consists of about thirty spots in compact circular field. Dimorphism not recognised.

Neoeuglyphella is only known from a single species, although it is possible that Euglyphella abdita

Peterson, op. cit. , 1966 should be assigned to this genus.

Hinge adont. Inner lamella fairly narrow with small anterior and posterior vestibula; marginal

zone narrow with straight, simple and short marginal pore canals. Muscle scar pattern of 6 central

adductors, of which 4 form an anterior arc, the uppermost one being the largest; behind this arc is

an elliptical/reniform scar with another, small contiguous oval scar posterior to it. Two mandibular

scars, a frontal scar and several dorsal scars are also present.

Stereo-Atlas of Ostraeod Shells 17, 107 Strumosia inandita (3 of 8)

Remarks: The genus Strumosia, from the M. Cretaceous of the Songliao Basin, differs from Ilyocyprimorpha

(Mandelstam in L.I. Galeeva, 1955, Cretaceous ostracods of the Mongolian People's Republic,

Gostoptekhizdat, Moscow, 47), to which its type species was first assigned, in having a thinner

shell, in having the left valve larger than the right, and in lacking the wide dorsal sulcus. Strumosia

tends to be more tuberculate, has a pustulose/spinose surface and the inner lamella and zone of

pore canals are narrower than in Ilyocyprimorpha. Strumosia is somewhat similar to the Brazilian

genus Sebastianites Krommelbein, 1962 (see J.W. Neale & Su Deying, Stereo-Atlas of Ostraeod

Shells, 17, 101-104, 1990), particularly in the pattern of tuberculation. It differs, however, in its

more quadrangular/trapezoidal shell, whereas in both species definitely assigned to Sebastianites

by the original author (5. fidus and S. devexus), both ends are symmetrically rounded. In

Strumosia the left valve overreaches the right valve dorsally, a feature not present in Sebastianites,

the ornamentation is pustulose rather than reticulate and is also present over the sulcus/

depression; the tuberculation is also much more accentuated.

All of the figured specimens are topotypic material.

Thick-shelled, finely reticulate Refrathella species with angular ventral lobe and distinct adventral

structure; cristal loop on ventral lobe anteriorly extended; dorsal plica developed.

Refrathella struvei Becker, 1967 belongs to the family Kirkbyellidae Sohn, 1961 (incertae

superfamily). It is distinguished from other species of the genus (and from the other Kirkbyellidae)

by its comparatively strongly developed ornamentation. Groos (Gottinger Arb. Geol. Palaeont., 1,

32, 1969) treats Refrathella Becker, 1967 as a subgenus of Kirkbyella Coryell & Booth, 1933; she

treats Berdanella Sohn, 1961 in similar fashion.

The Kirkbyellidae Sohn, 1961 do not belong to the Kirkbyacea Ulrich & Bassler, 1906, as was

already pointed out by Sohn (Treatise Invertebrate Paleontology, Part Q, 3, Q131, 1961). Most

probably, they show relations to forms described by Schallreuter (Wiss. Z. Ernst Moritz

Arndt-Univ. Greifswald, 17, 144, 1968; 21, 207, 1972) and Gramm (Paleont. Zh. 21, 95, 1988) from

Ordovician and Lower Carboniferous beds respectively from Northern Europe. R. struvei is

considered to be a benthic species.

Ardenno-Rhenish Massif; middle Devonian (Fromelennian) to upper Devonian (Refrath

Formation, Frasnian).

ON BAIRDIA CURTA M’COY

by Gerhard Becker, Michel Coen & Thomas Jellinek

(University of Frankfurt, Germany

& University of Louvain-la-Neuve, Belgium)

Genus BAIRDIA M’Coy, 1844

Type-species (subsequent designation by Ulrich & Bassler, 1923): Bairdia curtus M’Coy, 1844.

Diagnosis:

Remarks:

Distribution :

Bairdiid with convex to straight dorsal margin and more or less pronounced dorso-anterior and

dorso-posterior margins; posterior extremity of the carapace distinctly pointed (“bairdiid” outline).

Left valve overreaches and overlaps the right valve. Distinct calcified inner lamella with vestibula.

Adductor muscle scar bairdiid. Surface smooth or with weak ornamentations.

According to Becker (Senckenberg. leth., 46, 414-415, 1965), three Bairdia subgenera are distinguish-

able: B. ( Bairdia ) M'Coy, 1844 (type-species B. curta M'Coy, 1844; dorsal margin convex,

dorso-anterior and dorso-posterior margins concave); B. (Rectobairdia) Sohn, 1960 (type-species B.

distressa Sohn, 1940; dorsal margin straight, dorso-anterior and dorso-posterior margins concave); and

B. (Cryptobairdia) Sohn, 1960 (type-species B. ventricosa Roth & Skinner, 1930; dorsal margin,

dorso-anterior and dorso-posterior margins gently convex rounded). Orthobairdia Sohn, 1960

(type-species B. cestriensis Ulrich, 1891) is considered to be a synonym of B. (Rectobairdia) Sohn, 1960.

Carapace in lateral view elongate. Dorsal margin moderately high with greatest height about

mid-length. Anterodorsal extremity somewhat angular; posterior extremity situated below mid-height.

Surface smooth. Species is comparatively large.

Bairdia curtus (= curta) was originally described by F. M’Coy (1844, 164) from a collection made by Sir

Richard Griffith. Later, the type specimen was freed from limestone matrix and redescribed by Jones &

Kirkby (1879, 567-568). Subsequently, M’Coy’s material was lost and is not to be found either in Irish or

British museums (see Becker et al., 1989, 29). Now, the lower Carboniferous sections in the vicinity of

Granard, the type locality, have been investigated with the intention of replacing the lost holotype of

Bairdia curta with a neotype (Becker et al., 1989, 1990). A specimen clearly corresponding to Jones &

Kirby’s drawings (1879, pi. 28, figs. 1, 2) has now been identified and is figured herein. After collecting

more material, it is intended that a neotype will be designated (see Becker et al., 1990).

B. (Bairdia) submucronata Jones & Kirkby, 1879 might be the most closely related species to B. curta

(cf. Becker et al., 1990).

ON ROBUSTAURILA SALEBROSA (BRADY)

by Noriyuki Ikeya & Namiko Hino

(Shizuoka University , Japan)

Genus ROBUSTAURILA Yajima, 1982

Type-species (original designation): Cythereis assimilis Kajiyama, 1913 ( =Cythere salebrosa Brady, 1869).

1982 Robustaurila gen. nov., M. Yajima, Bull. Univ. Mus. Tokyo, 20, 212.

Carapace subrectangular in lateral view, subtriangular in anterior and posterior views. In lateral

view, anterior broadly rounded, posterior truncate with distinct caudal process, ventral margin

obscured by overhanging alae. Surface often coarsely pitted or reticulate; costate with 4 or 5 strong

ridges radiating from the prominent subcentral node: anteriorly 2 or 3, posteriorly 2, with a

prominent earlike projection on the ridge extending to the posterodosal corner. Hinge

amphidont/heterodont with a bilobate posterior tooth in the RV and a smooth median element in

the adult stage. Central muscle scars situated just inside the subcentral node: 4 adductor scars, the

middle two generally subdivided, and 3 frontal scars. Sexual dimorphism weak; female somewhat

larger and more inflated than male.

In her original description of Robustaurila , Yajima (1982, op. cit.) designated Cythereis assimilis

Kajiyama, 1913 as the type-species; however, her illustrated specimens belong to a different

species, R. ishizakii (Okubo) (N. Ikeya & H. Hamada, Stereo-Atlas Ostracod Shells, 17, 137-144,

1990). Robustaurila resembles Mutilus Neviani, 1928 (Memorie Accad. pont. Nuovi Lincei, ser. 2,

in shape and surface ornamentation, but basically differs in having radial ridges arising from a

subcentral node and in lacking the “tubular normal pore canals'’ given as a special generic

definition for Mutilus by W. Sissingh (1972, Utrecht micropaleont. Bull., 6, 124). Robustaurila also

has no “higher chimney-like structures and stellar tubercles" which are described on Mutilus by

Ruggieri & Sylvester-Bradley (1973, op. cit.). All normal pores of Robustaurila have a sieve plate

with a subcentral bristle opening, and are divided into two types based on the pore size and its

situation on the valve surface; one has a large sieve plate (5-10 pm in diameter) with a short bristle

in a depressed surface, and the other has a small sieve plate (3-4 pm in diameter) with a long

bristle emanating from a raised surface. The number and distribution pattern of the latter small

pores are quite constant in the genus, which in Japan comprises three species: the type-species, R.

ishizakii (Okubo) and R. kianohvbrida (Hu) (N. Hino & N. Ikeya, Stereo-Atlas Ostracod Shells,

17, 129-136, 1990).

Distribution: Pliocene-Recent; Japan and its adjacent area.

A large, subquadrate, less reticulate species of Robustaurila with strong radial ridges of which the

posterodorsal one is sinuous. Reticulation almost disappearing in posterior area and above the

subcentral node. Posterodorsally, cardinal angle sharp, with a distinct, small marginal spine in the

left valve. Posteroventral margin with several denticles. Ventrolateral alae expanded posteriorly.

In dorsal view, marginal rim relatively broad and flat. Left valve much higher than the right. The

ejaculatory duct is bent.

The species is similar to R. kianohybrida (Hu) (N. Hino & N. Ikeya, Stereo-Atlas Ostracod Shells ,

algae from Unarizaki, Awaji-shima, Hyogo Pref., Japan (lat. 34°16.7'N. long. 134°39.8'E) in lm

water depth on July 1st, 1984.

Diagnosis: A large, subquadrate, simple skeletally ornamented species of Robustaurila with strong radial

ridges and some tubercles on a smooth surface. Posterodorsal ridge strongly sinuous,

anteroventral one most prominent. Posterodorsally, cardinal angle sharp, with a distinct, small

marginal spine in the left valve. Posteroventral margin with several denticles. Ventrolateral alae

sharply curved posteriorly. In dorsal view, marginal rim broad and flat. Left valve much higher

than the right. The ejaculatory duct is bent with a widened base.

Remarks: The species is very similar to R. salebrosa (Brady) (N. Ikeya & N. Hino, Stereo-Atlas Ostracod

Shells, 17, 121-128, 1990) except for its skeletal ornamentation. Although the type specimen

seems to have lost the point of the caudal process and some detail of the ornamentation (as often

observed in weathered material), it corresponds with well-preserved Japanese specimens in other

morphological characters. Hu's material (1984, op. cit., TNUM 8137) designated as Ambostracon

metanodulose is correspondent with the A-l instar of R. kianohybrida in size and morphological

characters, which are faint reticulations, nodulous radiating ridges and some knobs. Hu's (1986,

op. cit., figs. 5, 8, 9 and 12) specimens also correspond with A-2 and A-3 instars of this species,

which have the characteristic faint reticulation in the posterior area.

Remarks: Although Mutilus sp. A (Ishizaki, 1968, op. cit.) has more fine reticulation and weaker radial

ridges, the characters of the outline and the reticulation pattern closely resemble those of the

present species. The specimens illustrated as the type-species of Robustaurila, R. assimilis

Kajiyama, 1913, by Yajima (1982, op. cit.), actually belong to this species. Appendages were

described by Okubo (1980, op. cit., figs. 6c-i, 7c, d).

Malzella bellegladensis (3 of 4)

Diagnosis:

Remarks:

Distribution:

Distinguished by having the greatest height in front of mid-length, a highly arched dorsum, distinct

eyespots, polished-appearing ridges, polygonal fossae, and a blunt caudal process of right valve.

This species differs from Malzella floridana (Benson & Coleman) ( Paleont . Contr. Univ. Kans.,

Arthropoda, Art. 1, 35-36, pi. 8, figs. 10-12, text-fig. 21, 1963) in having more subdued,

polished-appearing ridges as ornamentation, polygonally-shaped fossae, a more highly and evenly

arched dorsum, and by its smaller size. In M. floridana the anterior half has rectangular fossae,

with dominant horizontal ridges.

This species differs from Malzella conradi (Howe & McGuirt) californica (Benson & Kaesler)

(R.H. Benson & R.L. Kaesler, Paleont. Contr. Univ. Kans., Arthropoda, Art. 3, 23-23, pi. 1, figs.

9, 10, text-fig. 12, 1963) in having a blunt, not pointed, caudal process in the right valve, a less

distinct posterventral ridge, larger and more distinct eyespots, a distinct posterior cardinal angle of

the left valve, and a more evenly arched dorsum of the right valve.

The ocular sinus of M. belleglandensis is similar to most members of the genus; it is elongate

parallel to the long axis of the shell, has a minor constriction that gives it a stalked appearance, and

has a shallow, terminal concavity that is the complement of the convexity of the eyespot’s inner

surface (Kontrovitz, Trans. Gulf Cst Ass. geol. Socs, 35, 428, 1985).

Reported from semi-consolidated lime muds from south Florida (type locality, TU 201).
