Octopus (?) sp. 

 Plate IT. Fig. 3. 



Two detached and somewhat mutihited 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 

 a 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 1 1 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 " Fish Hawk." 



In order to complete the list of Cephalopoda 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 Verrill. 

 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.
