212 Records of the Indian Museum. [Vor. XIX, 
large four-lobed cirrus at the centre of its dorsal edge; arms 
about three times the length of the mantle; umbrella about a 
quarter the length of the arms, a little higher laterally, about 
equal elsewhere, not continued on outer margins of arms ; mantle- 
opening placed just behind, and on a level with, the posterior end 
of the eye ; siphon reaching about half way to the edge of umbrella. 
Colour above greyish, produced by minute red-brown chromato- 
phores closely sprinkled on a buff ground; paler below, with 
fewer and larger chromatophores. On the outer surface of each 
arm there is a row of four to six large dark chromatophores which 
cease at about the edge of the umbrella, or, more rarely, a little 
above it. Numerous small pointed tubercles are scattered over 
the dorsal surface. The ventral mantle is smooth except for a 
median groove, Compared with the descriptions of Hoyle, Wilker 
and Berry of young specimens of this genus, the present example 
seems to be nearest to Polypus H. (Hoyle, 1904, p. 197) and 
Polypus M. (Hoyle, 1907, p. 455).

This young example does not seem to agree with the charac- 
ters of any of the described species, and the comparison is rendered 
more difficult by the mutilation of the ventral arms which are 
represented only by stumps with the first two suckers, and as a 
consequence of this much of the umbrella is also absent. The 
principal characters are: elongate body ; prominent eyes; arms 
two and a half times the length of the mantle, with large suckers, 
the first four being placed singly ; umbrella (where present) about 
one-fifth the length of the arms, continued conspicuously on the 
outer margins of the arms almost to the extremity ; mantle-opening 
at ventral edge of eye; siphon somewhat pointed and reaching 
above arm roots, siphonal organ probably W-shaped but is not in 
good condition; dorsal surface, and inside of umbrella between 
dorsal arms, much wrinkled and with many small tubercles, the 
latter becoming less numerous on the mantle which has a smooth 
ventral surface without a median groove, only a few elongate
