This well-known West-Indian species has not been previously 

 recorded from the eastern side of the Atlantic. Of the two specimens 

 obtained by Dr. Conry, one, which has lost the spiral striatiori 

 through being beach-rolled, is very remarkable, and plentifully 

 spotted with the opaque white which is so characteristic of this 

 species. The other specimen is in fresh condition, and possesses all 

 the features of typical examples from the West Indies. The shell 

 figuied by Sowerby (Thes. Conch, pi. 353. fig. 20-^) under the name 

 of M. barbadensis is an immature specimen of this species.
