at stations 865 to 867, 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 species was associated, at station 869, in 192 fathoms, mud, with 
Octopus Bairdti and Rossia sublevis. 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.

(figures excellent). 
A good specimen of this species, in nearly perfect preservation, was 
recently presented to the United States Fish Commission by Capt. Will- 
iam Demsey and crew, of the schooner “Clara F. Friend”. It was taken 
from the stomach of a cod, off Seal Island, Nova Scotia.

about equal, somewhat shorter than laterals; tentacular arms slender, 
compressed (the ends absent). Fins small, thin, transversely rhomboidal, 
white. Color reddish brown. The ventral surface of the body, head, 
and arms is more ornamented than the dorsal surface, being covered with 
large, rounded verruce, their center or anterior half pale, the border or 
posterior half dark purplish brown; upper surface of body with mueh 
fewer and smaller scattered verruce; a circle of the same around the 
eyes; inner surfaces of arms and buecal membranes chocolate-brown.
