conical, and taper evenly to fine points. The suckers are in two 
series throughout, pedunculate, spherical, with a lateral aperture 
directed inwards ; the horny ring is smooth and surrounded by a 
few large papillae. The hectocotylus is not developed. There is no 
trace of an umbrella. The buccal membrane is well developed and 
has the usual seven points, but they are not very well marked nor 
provided with suckers ; the membrane is not connected with the 
arms by ligaments. There seems to be only one lip , which is thick 
and papillate. 
The Tentacles arise directly between the third and fourth arms, 
exactly resembling them at their origin, and obviously being part of 
one series with them; the stem is swollen at first and somewhat 
more than one-third up the arms narrows rather suddenly to about 
half its previous diameter. The club is wanting. 
The Surface is smooth. 
The Colour is a dull purplish madder, paler on the fins (especially 
their under surface) and on the arms and tentacles. 
The Gladius has not been extracted.

The Body is elongated, widest anteriorly, and tapering gradually 
to an acute point behind. The fin is comparatively short, only one 
third the length of the body, elliptical, slightly broader than long. 
The mantle-margin passes almost straight across the back, except 
where a long narrow median process juts out over the head ; it is 
slightly sinuate ventrally. The siphon is short and blunt. 
The Head is short and very nearly as broad as the body ; it has 
the usual auricular crest and preocular pore. 
The Arms are unequal, the order of length being 3, 4, 2, 1, and 
about one-third the length of the body ; the first has a distinct web 
on its dorso-median angle, and the third a still broader web on its 
outer aspect, passing back nearly as far as the eye, where it becomes 
connected with another passing up the dorso-lateral aspect of the
