Off Block Island, 29 fathoms, sandy mud : off Boon Island, 95 fathoms, 

 muddy, (A. S. Packard). Massachusetts Bay, in fish stomachs, (Pour-

 Comparative Zoology perhaps the original ones described by Pour- 

 tales ; the locality given is evidently erroneous. 



The single specimen from off Block Island is small and imperfect, and 

 may not be this species.
