two regular rows throughout the whole length. Anterior edge 
of mantle scarcely sinuous, advancing but little dorsally. Upper 
surface of the body and head nearly smooth, but in the larger 
specimens usually with a few very small whitish papillee, most 
numerous near the: front edge of the mantle. Color nearly as 
in the preceding species. 
One of the largest specimens measures, from base of arms to 
end of body, 46™; length of body, 31; of head, 15; breadth 
of body, 22; of head, 23; length of fins, 20; of their insertion, 
16; breadth of fins, 10; front edge of fin to edge of mantle, 2°5; 
length of free portion of dorsal arms, 16; of second pair, 17 ; of 
third pair, 20; of ventrals, 15; of tentacular arms, 25; breadth 
of dorsal arms at base, 8; of second pair, 8; of third, 35; of 
ventrals, 3°5; of tentacular arms, 35; of their terminal portion, 
3°75; its length, 10; diameter of largest suckers of sessile arms, 
‘8; length of free portion of siphon, 7™™. 
Taken with the preceding species, and is the more common of 
the two, in Massachusetts Bay. The differences may prove to 
be only sexual, but this cannot be determined without a larger 
number of specimens. 
Octopus granulatus Lamarck; D’Orbigny.

_ The smaller form of this species was taken with the last, 
living, and in about equal abundance. It has hitherto been 
as eminently arctic. We have recently received

additional specimens, taken in 200 fathoms, off Sable L, by the
