Granocardium (Ethmocardium) pomeyroli Keen, n. sp. Paratype, Stanford Univ. Paleo. Type Coll. No. 8290, camera lucida drawing of latex cast, slightly restored; X i- Shell large for the subgenus, ovate-quadrate, with about 25 ribs; ribs narrower than the interspaces, shallow, rounded on top, with ver- tical sides; intercostal spaces of the central 10 to 12 ribs internally bridged by thin bars of shell material which give the appearance of pits or pores when the thin outer layer is eroded away; hinge short (right valve longer than left), straight, cardinals 2a and 3b strong; anterior and posterior lateral teeth strong, the hinge plate hollowed out between laterals and cardinals; pallial line obscure, probably entire; anterior adductor muscle scars moderately large, remote from ventral margin; posterior muscle scars inconspicuous but apparently also re- mote; shell margins crenulate, posteriorly digitate. Difnensions.—Holotype, height, 27 mm., length, 27, convexity (one valve), 11; 25 ribs. Paratype, height, 27 mm., length, , convexity (one valve), ; 25 ribs.

Rene Pomeyrol, 1951; 30 specimens. Repositories.—Stanford Univ. Paleo. Type Coll., holotype, No. 8287, paratypes Nos. 8288-8294; other paratypes to be deposited in the collections of California Academy of Sciences, U. S.
