the outer ones of the arms, arranged in many crowded rows, some of 
which extend beyond the club along the arm 5 in the middle (fig. 1 b) 
there are usually one or two larger suckers (absent in our specimen), in 
which the horny ring has a small aperture, and is developed into a large 
hook-shaped claw on one side, and a complete circle of small plates sur¬ 
rounds the horny ring. 
Pen thin and delicate, narrow anteriorly, with slender lateral ribs; 
posteriorly, for more than half the whole length, expanded into a thin 
lanceolate form; posterior tip laterally dilated, with the edgQS involute

A young specimen of this species, in nearly perfect preservation, was 
recently presented to the United States Fish Commission by Capt. Will¬ 
iam Demsey and crew of the schooner “ Clara F. Friend.” It was taken 
from the stomach of a cod, off Seal Island, Nova Scotia. 
Greenland (Fabricius, Moller). Porsangerfjord, northern coast of Nor¬ 
way (G. O. Sars). Coast of Fiumark, in stomach of “coal-fish,” abun¬ 
dant (G. O. Sars, Norwegian Exp. of 1878). 
D’Orbigny, Gray, and other writers have erroneously referred the 
Onychoteuthis Fdbricii (based on the Sepia loligo of Fabricius) to 0. 
Banksii. The detailed Latin description given by Fabricius applies 
perfectly to the present species, and not at all to 0. Banksii. He de¬ 
scribes the four rows of suckers 011 the short arms, the small suckers and 
two large central hooks on the tentacles, the short caudal fin, etc.

Body elongated, tapering to a point posteriorly, shorter and less acute 
in the female, often very large ( Architeuthis ). Sessile and tentacular 
arms without hooks, but provided with suckers, having denticulated 
horny rings; tentacular arms with an expanded club, having four rows 
of suckers on its middle portion, those in the two central rows larger; 
proximal portion with or without smooth-ringed connective suckers and 
tubercles; tip with a cluster of smooth-ringed suckers. Siphon in a deep 
groove, attached by four bridles and strengthened by a median longi¬ 
tudinal dorsal band, free in the middle; an internal valve. Eyes with a 
round pupil; lids free, with a distinct anterior sinus. Nuchal or audi¬ 
tory crests consist of three longitudinal membranes on each side, united 
by a transverse one in front. Connective cartilages of the mantle three; 
the lateral ones in the form of a longitudinal ridge, with a smaller trans¬ 
verse one across its posterior end; corresponding cartilages on the siphon 
long-triangular, with a longitudinal and a transverse groove. Two ovi¬ 
ducts. Hectocotylized arm of the male either the right or left ventral. 
Pen usually very narrow along the middle portion, and with three
