extend on to the ventral surface of the body, where they become 
much smaller, more even, and average less than 1 mm. in diameter. 
Above each eye there seems to have been a short cirrus, but these 
have been rather damaged. 
The Colour is a dull purplish-grey, very dark above, much lighter 
below.

The Body is evenly rounded, with a slight depression in the 
median ventral line. The mantle-opening extends less than half- 
way round the body, terminating immediately below the eye, and 
further from it than from the base of the siphon, which is long and 
pointed, has rather a small opening, and extends two-thirds the 
distance to the umbrella-margin. 
The Head is short, and not so broad as the body ; the eyes are 
only slightly prominent. 
The. Arms are subequal, nearly four times the length of the body, 
and taper evenly to fine points. The umbrella extends one-third 
up the arms, and is a little wider laterally than dorsally. The 
suckers are closely set, deeply cupped, and marked with regular 
radial grooves ; their biserial arrangement commences immediately 
after the first. One arm bears a supernumerary sucker in the 
larger specimen. The hectocotylus is of the usual shape and of 
medium length ; it bears fourteen transverse ridges, each subdivided 
into four minute papillae. The circumoral lip is low and narrow. 
The Surface is covered with warts, which are largest and most 
numerous on the dorsal surface of the body, head, and umbrella, 
and dorsal aspects of the arms, where they have a quadrifid or 
quinquefid form, usually with a small wartlet in the centre, each 
forming a figure like a star or rosette. Towards the ventral surface 
and on the sides of the arms the warts are simple, and much smaller. 
On the back are about ten long cirri, which are rough with small 
warts, and above each eye is a very large arborescent cirrus with six 
or seven smaller ones beside it. 
The Colour is a pale purplish-grey, shading off to a creamy white 
on the ventral surface.
