168 AURICULACEA. 



Length more than seven twentietlis of an inch. I am indebted 

 to Mr. Stephen Elhott for this species, who obtained it on the coast 

 of South CaroHna. It is closely allied to Bulimus monile Brug., 

 but it has no appearance of bands, which distinguish that shell. In 

 the collection of the Academy are specimens from the West Indies.

Remarks. It is not now known what shell Say had in 

 view when the above description was written. No au- 

 thentic specimen is preserved, and no author has seen any 

 shell from that locality answering to the characters laid 

 down. DeKay mentions it among the extra-limital spe- 

 cies in his report, his words being nearly a repetition of 

 Say's. Pfeifter repeats Say's words, and suggests the 

 identity of the species with Melampus coffea. Say being 

 familiar with that shell {M. coniformis, vid. ed. Binn. 

 p. 85), it seems hardly probable he would have described 

 a variety of it. 



The question must remain undecided until we are bet- 

 ter acquainted with the species of the South Carolina 

 coast.
