The Tentacle is shorter than the body and slender ; the stem has 
three sides, the inner being slightly hollow, with a slender fillet 
along the middle. The club is slightly expanded with a distinct 
protective membrane ; the inner side of the club is deeply grooved, 
and internally to the groove is a rather broad fin. The suckers are 
in about five series, near the inner margin are three rather larger 
than the rest, which gradually diminish towards the outer margin. 
The horny rings of the larger suckers have about twenty fine teeth on 
the distal semicircumference, the smaller have fewer in proportion. 
The Surface is smooth all over. 
The Colour is a dark purplish grey above, paler below. 
The Shell is a very elongated oval in outline ; the chitinous 
margin is very narrow and extends one-third over the dorsal 
surface, which is smooth and evenly convex, with the exception of 
a slight ridge along the middle line : the ventral surface is elevated, 
so that the shell is thick, with a shallow median groove becoming 
evanescent posteriorly, the last loculus occupies one-tliird of the 
surface, and is bounded by a slightly curved line with a cusp where 
the median groove meets it : the inner cone is formed by two limbs, 
which arise half-way along the shell and form a rounded fillet 
slightly more elevated posteriorly, where they bound a shallow 
depression : outside them the margin of the shell expands into a 
subcircular plate, from the centre of which the spine projects 
backwards ; no information can be given as to its form or length, 
as it has been broken off close to the base.

The Body is elongated, broadest about one-third back, pointed 
behind : the fins extend the whole length of the body and are one- 
third of its breadth, a little wider behind ; they extend to within 
1 millim. of the anterior margin, but are separated by about 5 
millim. posteriorly : the mantle-margin projects far over the head 
dorsally, and is slightly emarginate ventrally. The siphon is 
conical, reaching two-thirds up to the gap between the ventral 
arms.
