2§2 A. E. Yerrill — North American Cephalopods. 
arms are long and slender, with broader clubs, which bear a large 
number of minute suckers, much like the outer ones of the arms, 
arranged in many crowded rows, some of which extend beyond the 
club along the arm ; in the middle (fig. 1 b) there is 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 surrounds 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 edges 
involute (fig. 1). 
A young specimen of this species, in nearly perfect preservation, 
was recently presented to the United States Fish Commission by 
Capt. William 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 
Norway (G. O. Sars). Coast of Finmark, in stomach of “coal-fish,” 
abundant (G. O. Sars, Norwegian Exp. of 1878 ). 
D’Orbigny, Gray, and other writers have erroneously referred the 
Onychoteuthis Fabricii (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 describes the four rows of suckers on the short arms ; the small 
suckers and two large central hooks on the tentacles ; the short 
caudal fin, etc. 
Chiloteuthis, gen. nov. 
Allied to EnoploteuthiSy lestoteuthis and Abralia , but with a more 
complicated armature than either of these genera. Sessile arms with 
sharp incurved claws, arranged in four rows on the ventral arms, and 
in two rows on the other arms, (distal portions have lost their arma- 
ture). Tentacular arms long, with broad clubs, strongly keeled ex- 
ternally, and with series of convective suckers and tubercles extend- 
ing for some distance along the inner surface of the arms. Tentacu- 
lar club provided with a marginal row of connective suckers, alter- 
nating with tubercles, along one margin; with a cenlral row of une- 
qual hooks, some of them very large; with submedian groups of 
small, slender-pedicelled suckers (or hooks) ; with marginal series of 
small suckers ; and with several rows of small suckers covering the 
prolonged distal portion of the face. Connective cartilages on the 
base of the siphon, simple, long-ovate ; the corresponding processes 
of the mantle are simple longitudinal ridges. The caudal fin. pen, 
and many other parts are destroyed.
