The Head is short, nearly as broad as the body, and the eyes are 
round and rather prominent. 
The Arms are equal, and about twice as long as the body; they 
are very stout, and taper gradually to blunt points ; their section 
shows a triangle projecting inwards, and a rounded surface looking 
outwards ; the former much more prominent than the latter. The 
umbrella is wide, extending one-third up the arms, a little further 
dorsally than ventrally. The suckers are comparatively small, closely 
set, and deeply cupped. There is no trace of a hectocotylus. 
The Surface is perfectly smooth. 
The Colour is dull purple, palest on the body, and deepest on the 
inner surface of the umbrella.

The Body is short, rounded, and depressed ; blunt behind, and 
deeply grooved below. The mantle-opening extends one-third round 
the animal, and terminates immediately below the eyes. The siphon 
is short, acutely pointed, and extends less than halfway to the 
umbrella-margin. 
The Head is short, and nearly as broad as the body. The eyes are 
spheroidal, and very prominent. 
The Arms are equal, and about half as long again as the body ; 
they are short, stout, and taper gradually to blunt points. The 
umbrella Extends halfway up the arms, — rather more in the largest 
specimen. The suckers are round, prominent, and deeply cupped, and 
there are about 30 on each arm. The hectocotylus is not developed. 
The Surface is smooth, with the exception of three cirri arranged 
in a triangle over each eye. Behind the left eye in the largest 
specimen the skin is elevated into a number of small papillae, and a 
few similar ones are seen on the back of the medium-sized specimen. 
The Colour is a dull purplish-grey above, inclining to pale ochre 
below.
