Stat. 95. 5°43'.5 N., 1 i9°4o' E. Sulu-archipelago. 522 M. Stony bottom. 1 Spec. 



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

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

 separate this from the young of interpunctata Sm., said to be from St. Thomas. St. Th. 

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

 at a depth of 522 M.
