Family Cypridinidae Baird, 1850 
Subfamily Philomedinae G. W. Miller, 1912 
Genus Euphilomedes Poulsen, 1962 
Philomedes (part).—Miiller, 1912.—Skogsberg, 1920. 
Euphilomedes Poulsen, 1962. 
Type spectes.—LHuphilomedes nodosa Poulsen, 1962, by subsequent 
designation, Kornicker (1967). 
GENERIC CHARACTERS.—Only a few additions are needed to Poul- 
sen’s diagnosis of the genus (1962, pp. 359-361) as amended by 
Kornicker (1967) to include E. multichelata. 
Sixth limb: The end joint of H. multichelata is comprised of two 
lobes; the proximal lobe bears a short, slender, hirsute bristle followed 
by three stout, plumose bristles. 
Seventh limb: The male of EL’. multichelata bears only five bristles 
on the seventh limb (4 distal, 1 lateral), the same number as reported 
on FE. oblonga (Juday, 1907). 
Euphilomedes multichelata (Kornicker, 1959)

Ho.toryre.—Specimen no. 686Z-6, Columbia University, Depart- 
ment of Geology. Gender: male. 
PARATYPES.—USNM 112940, 10 males. 
Hypotyrre.—USNM 112985, 1 female. 
TypE LocaLity.—Holotype and paratypes were collected at night 
off the end of the Lerner Marine Laboratory on North Bimini, B.W.I. 
The female described in this paper (USNM 112985) was from sediment 
approximately a mile east of the Bimini Islands. 
Draanosis (revised) —Euphilomedes with five primary claws and 
six to nine (usually eight) secondary claws. Second joint of exopodite 
of sixth limb bilobed, with small bristle followed by three large bristles 
on proximal lobe. Seventh limb of male with one lateral and four 
distal bristles. Anterior surface of valves with irregular polygons 
distributed in shingle-like pattern. 
DEscRIPTION OF MALE.—Shell (figs. 1, 32): oval, elongate with 
greatest height near middle, prominent rostrum and broad rostral 
incisure (figs. la, 6); anterior margin of rostrum and anteroventral 
margin of shell with scalloped outline formed by crescent-like marginal 
denticulations. Anterior surface of valves with irregular polygons 
distributed in shingle-like pattern (fig. 1c). Posterior dorsal margin 
with linear hinge depressed below outline of shell; hinge not visible
