Octopus (?) sp. 
Plate IV. Fig. 3. 
Two detached and somewhat mutilated arms, with portions of a third arm 
and of the basal web of a large Octopod, were taken at Station 336, N. Lat. 
38? 21/ 50", W. Long. 73° 32’, in 197 fathoms. 
The largest of these arms is 420 mm. long and 36 mm. broad, The suckers 
are large, prominent, subglobular, with a contracted aperture, and having 
à thin membrane around the outer margin. "They form two alternating, rather 
distant rows, except near the base, where several that are somewhat smaller 
than those farther out stand nearly in one row with wide spaces between them. 
Diameter of largest suckers, 9 to 11 mm. ; distance between their centres, 20 to 
35 mm. Color, dark purple. 
Additional Species dredged in the same Region by the U. S. Fish Commis- 
sion Steamer “ Mish Hawk." 
In order to complete the list of Cephalopods from the region explored last 
season along the United States coast, descriptions and figures are here given of 
four remarkable additional species, obtained by the U. S. Fish Commission 
party, on the “ Fish Hawk,” Lieut. Z. L. Tanner, Commander. Some of these 
were also obtained by Lieut. Tanner on an independent trip, made, November 
16th, to the region off the mouth of Chesapeake Bay. 
CHELOTEUTHIS Vxmurr. 
Trans. Conn, Acad., V. p. 292, Pl. XLIX., Jan. 1881. 
Related to Enoploteuthis, Abralia, and Lestoteuthis, but with the armature 
of the tentacular arms more complicated than in 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 (absent on the distal portions), 
Tentacular arms long, with broad clubs, strongly keeled on the outer side, 
distally, and with series of small connective suckers and tubercles extending 
for some distance along the inner surface of the arms. Tentacular club pro- 
vided with a marginal series of larger connective suckers, alternating with 
rounded tubercles, along one margin ; with a central row of unequal hooks,
