Shell oval, veiitricose, pale reddish brown, back darker ; longi- 

 tudinal striae sharp, distant, distinct, some few of them ending be- 

 fore they reach the back, but most of them terminating in a white 

 tubercle on the edge of the dorsal groove, which is very broad and 

 white. Base rather flat, with both the edges considerably and 

 sharply margined when full grown. The mouth linear, as long as 

 the shell, and slightly curved towards the hidden spire. Teeth of 

 the inner lip ]2, outer 15 ; those of the outer lip often having one 

 or two small teeth placed between some of the longitudinal stria;. 



Length I, breadth | of an inch. 



Lamarck refers to all tlie figures above quoted, except the last, 

 for his Cj/prwa Onisciis, but his description agrees exactly with the 

 full grown Cypraa aperla of RJr.Svvainson, as he expressly says that 

 it is known by its large mouth. Mr. Dillwyn has used the above 

 quoted name of Lamarck, but has accurately described the shell 

 intended above, which has also been equally well described by 

 Lamarck, under the denomination of Cj/prwa radians, a name that 

 Mr. Dillwyn has entirely omitted. 



I have a worn specimen of a shell which certainly differs from 

 this species. It has 1 1 teeth on the inner and 13 on the outer lip ; 

 the edge is thickened, rounded, and margined above ; and the dor- 

 sal groove is much broader than in C. sulcata, but not so broad as 

 in C. radians. It is of a pale reddish white, and as large as, and 

 broader than, C. sulcata. It is perhaps a new species.
