Cyprmi nucleus, var. b, Lamarck. 



H(ib. Madagascar. 



This species is uniformly larger in size than the C. uu- 

 cleui, much more depressed, and of a peculiarly soft pink-

 the ridges across the left base are alternately larger and 

 smaller.

It is a cu'cumstance worth noting in the growth of this 

 shell that the teeth beome considerably developed before 

 there is any indication of dorsal pimples.
