CEPHALOPODA. A75 
Surface rough, covered with warty granulations, which are especially 
large and prominent on the back of the head and the upper half of the 
umbrella; on the lower face they are less prominent and much smaller, 
and over the posterior part of the sac they are flattened and even 
pitted at the centre, resembling pavement or rubble-work. Over the 
eyes are three elongated tubercles or cirrhi, and apparently one below; 
and a longitudinal’series of three of them running along the head to 
the back of the four superior arms. 
Length of sac to the mouth, two and a half inches; length of upper 
arm, twelve inches; of superior lateral arm, sixteen inches; of inferior 
lateral arm, sixteen inches; of inferior arm, thirteen inches; breadth 
of umbrella, five inches; breadth of arm, two or three inches from 
origin, two and a half inches; diameter of largest cupules, half an 
inch. 
Found near Sydney, New South Wales. 
This is a very robust and powerful species, closely allied to O. vul- 
garis, which it resembles more than any other species. As presented 
by the specimen from alcohol, the arms are unusually stout. And the 
whole concave face of the umbrella is completely paved with large 
cupules, merely a narrow fissure appearing to mark the division of the 
arms. ‘The mouth is so small, that the jaws are entirely concealed. 
The surface is coarsely reticulated or warted, like O. vulgaris, resem- 
bling the skin of a tortoise; but the size of the eyes, the arrangement 
of the cirrhi, and other obvious marks, distinguish them. O. rugosus, 
Blain. (O. granulatus, Lam.), is also closely allied, but has a smoother 
surface, only a single cirrhus, and arms less developed.
