MELVILL : MOLLUSCA OF S. CAROLINA AND FLORIDA. 1 57 



11. Hemifusus corona y3 estephomenos (Melv.) 



This marked variety may probably be constituted a 

 new species. It differs from the type in being uniformly 

 smaller, and in the almost complete absence of one of the 

 two rows of spines on the last whorl. 



It was found in one place only at Key West, but 

 there in great abundance on very shallow coral slabs, 

 covered with about two feet of water, and surrounded by a 

 brackish Mangrove swamp. 



(It has been figured by Sowerby in Zool. Pro., Nov., 

 1878. Plate xlviii, f. 13.)
