The shells associated with this species differ somewhat 

 from the description given by Grould in having, besides ' the 

 widened groove,' a lanceolate depression or posterior lunule 

 which extends from the umbones down the dorsal slope. It

 Hob. Discovery Bay, 5-^ fms. (Feilden).

Hob. Eichardson Bay, 80 2' N. lat., 70 fms. (Feilden). 

 The specimens from the above locality have the transverse 

 costse rather finer than is usual.
