MELVILL : MOLLUSCA OF S. CAROLINA AND FLORIDA. 1 59 



Fiun : FASCIOLARIDJE. 



30. Fasciolaria distans (Lam.) 



Charleston Harbour. Not uncommon. 



31. F. tulipa (L.) 



Key West and Cedar Keys, West Florida. 



32. F. scheepmakeri (Dunker.) 



I was fortunate in finding two specimens of this rare 

 mollusc, both fine, though in dead condition, on the southern 

 shores of Key West. It appears to differ from F. tulipa 

 (L.), its nearest congener, by the more massive build, and by 

 being uniformly ribbed throughout. 



33. Busycon aruanum (L.) 



Very common and fine on Sullivan's Island, South 

 Carolina — frequently attaining a large size. 



34. B. perversum (L.) 



This is probably a sinistral var. of B. aruanum. I 

 found them associated together in Carolina, but on the West 

 coast of Florida and at Key West I found only the 



perversum. 



35. B. canaliculatum (L.) 



Charleston Harbour. Not common. 



36. B. spiratum (Lam.) 



Key West. One specimen. 



37. Leucozonia knorrii (Desh..) 



On the coral reefs. Key West. The animal is of the 

 color of raw beef. 



38. Latirus Cayohuesonicus (Sowb. and Melvill, 1878.) 



This interesting little species was recently described by 

 Mr. Sowerby in the Zool. Proceedings (Nov. 5, 1878). It is 

 in form almost an exact minature representative of the
