Y. ); Science; Museums. 96 [Senate nally, most ventricose near the central and umbonial region, depressed and having a broad shallow flat or subangular mesial sinus in front, terminating (in old specimens) in a linguiform extension : dorsal valve elevated and rounded along the middle, declining laterally, having (in old specimens) a strong rounded mesial fold in front; beak incurved. Surface marked by ob- scure traces of very fine radiating stria3, which are crossed by indistinct concentric lines of growth. This fine large species differs considerably in the form and depth of the mesial sinus, as well as in the greater or less extension of the mesial pro- longation of the anterior border of the ventral valve. In some of the spe- cimens the sinus is very shallow and flattened within, while in other in- stances it is more impressed and angular in the middle : other specimens present intermediate grades of difference in this respect, the sinus being nearly fiat within, and marljed by a narrow, nearly linear, deeper depression.
