The arms are numbered from the dorsal to the ventral aspect on the right 
and left sides respectively. It will be seen that the position of the enlarged 
suckers is not constant in the same specimen, nor even in the two arms of 
the same pair. 
POLYPUS sp. ? 
Locality.—St. Vincent, Cape Verde Is.; six young specimens, ? [1444— 
1449]. 
These six young Octopuses came in the same bottle with five that I have 
named Polypus vulgaris [1439-1443], and I am not quite sure that they may 
not be a variety of the same species, but they differ in being much paler and 
of a reddish rather than a purplish-brown colour above. The dorsal surface 
of the back, head, neck, and roots of the upper arms is covered with small 
hemispherical papille, not rough, irregular warts. They have two papille 
over each eye, and one example has four arranged in a rhomb on the back. 
In some respects they resemble Polypus granulatus, but the colour is different 
and the rough surface does not extend over the inner aspect of the umbrella. 
On the whole I am inclined to think they are not P. vulgaris, but I nave 
failed to identify them with any known form and think it would not be 
advisable at present to propose a new species for their reception.
