arms, with the terminal club elongated and somewhat expanded. 

 The club bears two central rows of prominent, incurved hooks, about 

 twelve in each row, not counting the very small ones near the tips ; 

 the hooks in the lower row are much larger than those in the upper ; 

 alternating with these, along each margin, there is a row of small 

 suckers, which extend to the extreme tip, becoming there very minute; 

 towards the tips the hooks are reduced to a single median row. At 

 the base of the club there is a group of six to eight small smooth 

 suckers intermixed with small rounded tubercles. The inner face of 

 the arm below the suckers is flat and white. 



The color, in alcohol, is rather deep purplish brown, both above 

 and below, but paler beneath ; it is due to rather large, rounded and 

 very distinct, brown, orange and purple chromatophores. Similar 

 chromatophores cover the outer surfaces of the arms, while the inner 

 surfaces are specked with very dark brown ones.

 30'"'" ; length of club, 12™™ ; its breadth, 2™™. 



The name Teleoteiithis was proposed by me in 1881, in place of 

 Onychia Les., because the latter was preoccupied for a genus of 

 insects by Hubner in 1816. 



One specimen (No. 40,129), was taken at the surface at station 

 2225, off" Chesapeake Bay. 



Benthoteuthis, gen. no v. 



Body rather short, well-rounded, oblong, blunt posteriorly. Fins 

 small, rounded, with a narrow insertion, situated close to the poste- 

 rior end. Head broad. Eyes large, with distinct lids and small 

 anterior sinus. Siphon short and wide, in a smooth groove, without 

 bridles, internal valve well-developed. The dorsal mantle-edge is 

 free, with an obtuse median angle, projecting over the back of the 

 head. Arms small and short, the dorsal ones shortest ; the lateral 

 ones keeled externally ; web I'udimentary ; marginal membranes on 

 the inner angles narrow. Suckers small, crowded, apparently in four 

 rows. Tentacular arms long and slender, the sucker-bearing portion 

 scarcely enlarged, bearing numerous minute, subequal suckers in 

 many rows. 



The pen is veiy thin, expanded into a broad lanceolate blade pos- 

 teriorly, very slender, with the edges incurved so as to form a groove
