On the basis of Guppy's figure in the Quarterly Journal, 

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

 C, verriLcosKS, with its siilcated sides and appressed or beveled 

 shoulder angle. Our collection contains a single specimen from 

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

 Cossniann's specimen of ?;iarghiafus from Martinique should 

 probably be referred to some other species.
