at Stations 805 to 8G7, in 65 fathoms ; 872 to 880, in 86 to 252 fathoms. 

 It was also obtained by Mr. A. Agassiz, at similar depths, in the same 

 region, as well as farther south, earlier in the season, while dredging on 

 the Coast Survey steamer "Blake". 



This si)ecies was associated, at station 860, in 102 fathoms, mud, with 

 Octopus Bair/lii and Eossia suhlcvis. It can easily be distinguished from 

 the latter and other species of Rossia, not only by the large suckers of 

 the lateral arms, but still better by the inequality of the suckers on the 

 tentacular club. The latter character is obvious in specimens of both 

 sexes and of all ages.

A good specimen of this species, in nearly perfect i^reservation, was

 iam Demsey and crew, of the schooner " Clara F. Friend". It was taken 

 from the stomach of a cod, oft' Seal Island, Nova Scotia.
