This shell is of about the same size as D. scripta, from all 

 the numerous varieties of which it differs in being thicker, 

 in having the umbones inclined towards the anterior slope, 

 and in the want of a cartilage cleft, and the serratures at the

 spots, and a longitudinal white ray ; the hinge resembles 

 that of D. cuneata. 



radiata. 17. Shell sub-oval, with concentric striae, 

 and the inside striated longitudinally ; hinge 

 with a single primary tooth in one valve, and
