MOLLUSKS FROM THE VICINITY OF PERNAMBUCO I47 



This neat shell is not quite mature and its aperture in the adult state 

 cannot be described, but is undoubtedly normal. The species belongs 

 in the section Crassispira near such species as D. albinodata Reeve, 

 but differs in details of sculpture as described from all those with which 

 I have compared it. It is named in honor of Mr. A. W. Greeley who, 

 under the direction of Dr. Branner, collected it and nearly all the speci- 

 mens mentioned in this paper.
