190 Records of the Indian Museum. [Vor. at 
the very pronounced difference commented upon by Brock be- 
tween the dorsal and ventral surface, the scoop out of the 
umbrella between the dorsal arms being also very marked. The 
Santapily specimen is of a reddish-purple colour above with an 
immense number of tubercles and oblong ridges, and a large 
cirrus at the posterior dorsal edge of eye. The examples M *47°, 
M *%* and M *#2° resemble each other very closely in size and 
appearance, and are dark grey above with no oblong ridges, but 
with a great number of round tubercles regularly disposed, and 
surrounded and intersected by small dark chromatophores, 
arranged sometimes in masses which causes a handsome appear- 
ance like black veins all over the dorsal surface of head, mantle 
and arms. A trace of this marbling occurs on one side of the 
Santapily specimen. Ocular cirri are present on specimen M +%>* 
and faintly visible on M °*° and suppressed entirely on M *47°. 
All four specimens possess a smooth ventral surface scattered 
thinly with reddish or brown chromatophores on a pale ground. 
The young specimen M **?* is obviously the same species as the 
three just mentioned, but is without the dark veinings, and shows 
two rows of large dark chromatophores on the upper arms, in 
addition to the small chromatophores. Ocular cirri are present, 
and there are close-set tubercles on the dorsal surface of head and 
umbrella, but the mantle is nearly smooth. Specimen M **%°* 
closely resembled two specimens in the British Museum, one of 
which labelled ‘‘ O. granulatus,’’ came from the Cape, and the 
other labelled ‘‘ P. polyzenia-granulatus,’’ came from Thursday 
Island, Torres Straits. 
Many arms are in course of regeneration in M °%*. The 
principal measurements of the other specimens are appended :—
