This is considerably larger than the type, and unfortunately 
resembles it in having the tentacles represented only by mutilated 
stems. There is a slight groove on the inner surface of the stem, 
and at about 3 mm. from the mouth there seemed to be two 
minute suckers, which, however, may have been only abrasions on 
the stem surface. A very delicate membrane unites the first and 
second pairs of arms extending to about the first sucker, but is very 
slight between the second and third pair and absent between the 
ventral arms. This membrane had probably been torn away from 
thetype. Only the rings on the distal half of the third arms could 
be examined without injuring the specimen. The suckers in this 
region have four or five short, widely-espaced teeth on the distal 
margin, the rest of the-ring being smooth. Colour dull white 
sprinkled on both sides of the mantle with small dark chromato- 
phores, arranged in about twenty-eight irregular transverse rows. 
When not contracted the chromatophores are reddish-brown and 
oblong. They are dark and narrow and placed transversely on 
the dorsal surface of the arms and are sometimes scattered amongst 
the suckers. They are present on the siphon but absent from the 
fins. The extraordinary eyes make this a species easy to inden- 
tify.
