50 LEPAS. 



The large specimen, fig. 4, is an old shell of the same 

 species, which has lost its spines, except the rudiments 

 of one or two that still remain on its upper surface. 

 The two young shells fixed on its side were probably 

 from eggs ejected by the parent.

A conic shell, with a pointed beak and six smooth
