The Arms are subequal, the two lateral pairs being a little longer 
than the others ; on an average they are nearly three times as long 
as the body, and taper rather rapidly about the middle of their 
length and then evenly to fine points. The umbrella extends nearly 
one-third up the arms, least along the dorsal pair. The suckers 
are sunken, comparatively large, with a dark margin and very 
well-marked radial grooves. The first two in each arm are in a 
single row, owing to compression of the arms laterally ; there are 
no enlarged suckers on the lateral arms. The hectocotylus is not 
developed. 
The Surface of the dorsum of. the body bears minute warts 
scattered here and there ; over each eye there is a rather large 
branched cirrus, with a few small ones scattered round it. The 
internal surfaces of the arms are covered with minute hemispherical 
warts, so as to resemble shagreen. 
The Colour is very dark grey, almost black on the dorsal surface 
and outside the arms; paler grey below and on the inner surfaces 
of the arms. The dark covering of the body is not continued over 
the inner surface of the membrane covering the two dorsal arms.

The Body is short and evenly rounded, with the merest trace of a 
median ventral groove. The mantle-opening extends about half 
round the circumference, and terminates halfway between the 
siphon and the eye. The siphon is relatively long, conical and 
pointed, and extends about halfway to the umbrella-margin. 
The Head is small, and the eyes rather prominent. 
The Arms seem to have been unequal, the lateral the longest, but 
so many have been mutilated that it is difficult to be certain ; 
they are about four times the length of the body. The umbrella 
extends about one-third up the arms, the furthest between the 
lateral pairs. The suckers are large, close, and prominent, 
with a narrow margin marked off from the basal portion; the 
radial grooves extend to the margin and form notches in it. The 
hectocotylus is not present ; the third right arm has been mutilated,
