[19,")] t'EPHALOPODS OF NORTHEASTERN COAST OF AMERICA 405 



those of the second pair, which are the longest ; the third pair are about 

 one-half inch (12 uim ) 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 recovery 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 ; 2d 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, oif 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 O. Grbnlandicus, 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 0. Bairdii, by its more 

 elongated body, its much longer and more tapered arms, with shorter 

 web; by the absence of the large, rough, pointed papillae, 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 Bosc. 



1 have seen several specimens of a large Octopus, allied to O. vulgaris 

 of Europe, which were taken at Beaufort, N. C, and near Fort Macon. 

 It is probably O. rugosus.
