 Rare. Not previously recorded in Great Britain. It is of 

 fairly frequent occurrence in tropical and sub-tropical seas, 

 ranging from shallow water down to 675 fathoms, the deepest 

 record, which is in the Challenger dredging, Station 120, off 

 Pernambuco. It does not appear to have been recorded any- 

 where north of the Cape Verde Islands.

 Very rare. Not previously recorded in Great Britain, but 

 Mr. Wright informs me that he has found it at Rockport, 

 Belfast Lough, Strangford Lough, and Carlingford, and that 

 Mr. F. W. Millett has obtained specimens from Torbay, 

 Devonshire. 



Brady records it from the South Pacific only. Mr. Millett 

 found it in the Malay Archipelago, and I have specimens from 

 anchor mud, Mauritius.
