On the basis of Guppy's figure in the Onarterl}^ Journal, 

 this cone is seen to belong to the type exemplified b}'^ the recent 

 C. verrucosus, with its sulcated sides and appressed or beveled 

 shoulder angle. Our collection contains a single specimen from 

 Zone 5 of Red Cliff Creek which is very close to Guppy's figure. 

 Cossmann's specimen of marghiatus from Martinique should 

 probably be referred to some other species.
