Description.—The following is Arnold’s (1903) description of this species: 
“Shell of medium size, elongated, narrow-ovate, rather thick; umbones 
posterior to center and pointing posteriorly; anterior portion of shell evenly 
rounded, the dorsal and ventral lines being nearly parallel; posterior dorsal 
margin depressed back of umbo, running off quite obliquely to a line which 
truncates the posterior end near the base; basal posterior angle nearly a right 
angle; basal line nearly straight; a prominent bifid cardinal tooth on each valve; 
pallial sinus long and narrow; generally thickened anteriorly.’’ 
Length, 48 mm. 
Occurrence —At station D 5843 (1). 
This shell is listed by Wood and Raymond from San Francisco. 
It occurs commonly along the beaches both north and south of the 
Golden Gate, but is not known to oceur within San Francisco Bay. 
A single valve was dredged in the vicinity of Mile Rock. 
Range.—Queen Charlotte Island, B. C., to Gulf of California 
(Dall).

concentrically grooved, with wider interspaces, the sculpture stronger on the
