This possesses a round body with a constriction at the neck, 
and a mantle-opening placed about halfway between the eye, 
and an unusually broad siphon ; the latter has a blunt apex, and

over the body revealing that the first four suckers on each arm 
are placed singly, and that all have the eighth, ninth and tenth 
suckers enlarged. Umbrella lowest dorsally, extending about one- 
third of the length of the arms, and continued on their outer 
margins. Terminal organ of hectocotylized arm very small. 
Colour of body grey with dark lines; arms reddish with light 
coloured patches, each of which is the seat of a cirrus. Cirri very 
numerons even on the ventral surface, many being much branched 
and measuring 2 mm. in length.
