The Body is rounded, widening a little posteriorly ; the ventral 
groove is very faint. The mantle-opening terminates just below the 
eyes. The siphon is bluntly conical, and extensively attached to the 
umbrella ; it extends less than halfway to the umbrella-margin. 
The Head is small, and the sides are entirely occupied by the 
enormous eyes, which are swollen and globular, but with very small 
palpebral openings. The skin covering them is so thin that the 
dark pigment within is distinctly visible. 
The Arms are unequal, the dorsal pair being the largest ; on an 
average they are four times as long as the body. The umbrella is 
about equally wide all round, except that it is a little shorter 
between the two ventral arms. The suckers are comparatively 
small, prominent, and separate ; more widely in one specimen 
than in the other, probably owing to its being less contracted by 
spirit. None of the suckers on the lateral arms are enlarged, 
notwithstanding the sex. The hectocotylus is well-developed ; it 
is broad, and tapers rapidly to an acute point; in one specimen 
about seven transverse ridges can be counted in the proximal half 
of the median groove ; in the distal half and in the other specimen 
they are indistinct. 
The Surface is perfectly smooth all over. 
The Colour is a pale purplish-pink ; deeper above than below.

The Body is spheroidal, very little longer than broad, and the 
ventral groove is not marked. The mantle-opening extends one- 
third round the body, ending some distance directly below the eyes. 
The siphon is slightly tapering, and extends one-third the distance 
to the umbrella-margin.
