A, E. Verrill—Mollusca of the New England Coast. 401 
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.

The name TZeleoteuthis 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. nov. 
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 rudimentary ; 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 very thin, expanded into a broad lanceolate blade pos- 
teriorly, very slender, with the edges incurved so as to form a groove
