The Head is much narrower, and more depressed than the body ; 
the eyes are scarcely at all prominent. 
The Arms are unequal, in the order 1,2, 3, 4 ; about six times as 
long as the body ; they are very long and slender, tapering but 
slightly. The umbrella is small. The suckers are small, prominent 
and closely set, and the first four stand in a slightly zigzag line. 
The hectocotylus is absent. 
The Surface is smooth for the most part, but the skin is wrinkled 
over the posterior acuminate extremity, owing to the action of the 
spirit ; there is one very small wart over each eye. 
The Colour is yellow ochre, with two pale sienna patches on the 
back and on the head. 
Habitat — Bermuda. 1 specimen, ? juv.

The Body is oblong, depressed, and bulges a little at the sides. 
The mantle-opening extends about one-third round the circumference, 
terminating about midway between the siphon and the eye, The 
siphon is short and small, extending scarcely one-third the distance to 
the umbrella-margin. 
The Head is almost as broad as the body; and the eyes are large, 
spheroidal, and prominent, with very small circular apertures. 
The Arms are subequal and short, compared with the body, being 
about three times its length ; they taper gradually to moderately 
fifie points. The umbrella is large, extending about one- third of the 
arms. The suckers are small and prominent, and arranged in two 
rows from the commencement ; a narrow well-marked groove runs 
across the arm between each two suckers (possibly due to contrac- 
tion). The hectocotylus is well-developed, short, and tapering 
rapidly to a blunt point ; the median groove has about ten transverse 
bars. The circumoral lip is unusually thick. 
The Surface appears to have been perfectly smooth, but is now 
covered with wrinkles, due to the action of the spirit. 
The Colour is a dull grey, inclining to stone-colour below. 
Habitat.— Off Heard Island, Southern Ocean; 75 fathoms 
(Station 151). 4 specimens, 1^,1^ juv., 2 ? juv.
