not half the length of the arms ; they are quadrangular and flattened 
from above downwards. 
The Surface bears a large number of papillae, slightly elevated, 
resembling those of Calliteutliis ; they are arranged most thickly on 
the ventral aspect of the head and body, but also on the dorsal, and 
extend up the outer aspect of the arms, three series on the ventral 
arms, two on each of the others. Near the tip of each dorsal arm 
is a series of four or five black, elongate, egg-shaped swellings, 
gradually diminishing in size, and forming apparently an extreme 
development of the papillae above mentioned. The second pair of 
arms appears to have been similarly provided ; the third has been 
so stripped of integument towards the tips that it is impossible to 
ascertain their original condition. In the fourth the warts at the 
tip are quite similar to those lower down the arm. 
The Colour is a dull purplish madder, paler above than below, the 
papillae are a deep black, with a white centre, usually situated 
towards the anterior margin. The buccal membrane , both sides of 
the umbrella, and the inner surfaces of the arms, so far as this 
extends, are a deep purple. 
The Gladius has not yet been extracted from the solitary 
individual.
