[ 195 ] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
those of the second pair, which are the longest; the third pair are about 
one-half inch (12 mm ) shorter than the second; the ventral pair about one- 
fourth inch (6 mm ) shorter than the third. In our specimen all the arms on 
the right side are somewhat shorter than those on the left, and the web 
between the 1st and 2d pairs is narrower, due perhaps to recover from an 
injury. The web between the arms, except ventrally, is of about equal 
width, and scarcely more than one-fourth the length of the arms, meas¬ 
uring from the beak. Between the ventral arms the web is about half 
as wide as between the lateral. 
The suckers are moderately large, alternating in two regular rows, 
except close to the mouth, where a few stand nearly in a single line; 
about fourteen to sixteen are situated on the part of the arms included 
within the interbrachial web. The whole number of suckers on one arm 
is upwards of seventy. 
Color of the alcoholic specimen, deep purplish brown, due to very 
numerous crowded, minute, specks; eyelids whitish. The front border 
of the mantle, beneath, and the base of the siphon and adjacent parts, are 
white; end of siphon brown. Lower side of head and arms lighter than 
the dorsal side. 
Total length, from posterior end of body to tip of arms, of 1st pair, 
158 mm; 0(1 pair, 160; 3d pair, 146; 4th pair, 133; to web between dorsal 
arms, 82; between ventral arms, 63; to edge of mantle, beneath, 30; to 
center of eye, 39. Breadth of body, 31; of head across eyes, 30; breadth 
of arms, at base, 55; diameter of largest suckers, 2.5; length of arms 
beyond web, 1st pair, 76 ; 2d pair, 82; 3d pair, 71; 4th pair, 69 mm . 
Two specimens of this species, both females, have been obtained. The 
first was from Le Have Bank, off Nova Scotia, in 120 fathoms, taken by 
Capt. John Mclnnis and crew, of the schooner “M. H. Perkins”, October, 
1879 (lot 530); the second was taken by Capt. David Campbell and crew, 
of the schooner “Admiral”, near the Grand Bank, north latitude, 44° 07'; 
west longitude, 52° 40', in 200 fathoms, December, 1879 (lot 590). 
This species resembles 0. Gronlandicus, of which the males alone have 
been described, and it may eventually prove to be the female of that 
species. 
This species is easily distinguished from O. Bairdii , by its more 
elongated body, its much longer and more tapered arms, with shorter 
web; by the absence of the large, rough, pointed papill®, or cirri, 
above the eyes, and by its general smoothness. The white color of the 
underside of the neck, siphon, and mantle-border also appears to be 
characteristic. 
Octopus rugosus Bose. 
1 have seen several specimens of a large Octopus , allied to 0. vulgaris 
of Europe, which were taken at Beaufort, U. C., and near Fort Macon. 
It is probably O. rugosus.
