The Body is almost entirely absent. The fin is obovate in form, 
and thickened along the posterior margin, thin and membranous at 
the extremity and along the anterior margin. The proximal end of 
its cartilage is exposed, and presents a long grooved articular surface. 
One branchia is visible, and presents the appearance of a spheroidal 
nodule with meridional grooves. The mantle- opening is circular, and 
closely embraces the base of the siphon, which is long, thin, and 
conical. 
The Head is exceedingly short, and the eye appears to occupy all 
the available space between the fin and the arms. 
The Arms are subequal, thick, rounded, and soft, and taper 
rapidly towards the extremities. The umbrella is attached directly 
to the arms, which are somewhat more prominent on its inner than 
on its outer surface ; it is attached to the dorsal aspect of every arm 
almost to the tip, aud to the ventral aspect for somewhat more than 
half its length, and at its attachment is a firm cartilaginous (?) 
nodule. The suckers are about fifty-two in number, and commence 
close to the oral lip, and the first half-dozen stand near together ; half- 
way up the arms they are farther apart, and the largest are situated 
opposite the attachment of the membrane to the ventral aspect of 
the arms ; they are prominent, but not so hard and firm as those of 
C. magna. There are faint radial markings upon them. The cirri 
commence on the dorsal arms between the seventh and eighth suckers, 
and continue till the last ; on the ventral arms they commence be- 
tween the sixth and seventh, and here also are continued to the tips 
of the arms. They begin as small papillae, gradually increase in 
length, attaining the maximum about halfway along the arms. 
The Surface is smooth. 
The Colour is a deep purplish madder, paler outside the umbrella 
and on the fin.
