The specimens are young-, somewhat bleached shells, one of them with only traces of 

 the brown colour. Mr. Smiiii, to whom I owe the identification, writes about it: "I cannot 

 separate this from the young of interpimctata Sm., said to be from St. Thomas. St. Tli. 

 may be wrong. It is a Cumingian locality". The specimen from Stat. 95 probably has not lived 

 at a depth of 522 M.
