408 A. E. Verrill— North American Cephalopods. 



The supposed female has lost the tail, but the arms are in better 

 condition than those of the male; it differs from the male in having 

 distinctly smaller suckers on the lateral arms. Length of dorsal arms, 

 •27"'"' ; of second pair, 44; of third pair, 46 ; of fourth pair, 37 ; of 

 tentacular arras, 120; of club, 16""". 



Two typical specimens wei*e obtained off Martlia's Vineyard, at 

 stations 1031 and 1033, in 255 and 183 fathoms; one of doubtful 

 identity, at 994, in 368 fathoms, by the U. S. Fish Commission, in 

 1881. All three were from fish-stomachs. 



I take pleasure in dedicating this interesting species to Dr. T. H. 

 Bean, the ichthyologist, who took charge of the fishes on the " P^ish 

 Hawk," this season.

A nearly complete male specimen of a Chiroteuf/ris, lacking only 

 the tentacular ai-ms and the distal portion of the left ventral arm, 

 was received after the preceding pages were put in type. The 

 stiimps of the tentacular arms, remaining, bear the same kind of un- 

 armed sessile suckers as did the arm described on p. 299, and figured 

 on pi. 47, figs, ^-Ih. It appears to be a new species, and is very 

 distinct from 0. Bonplandii. Tlie sessile arms are very large in 

 proportion to the head and body, and the ventral arms are much 

 laro-er than any of the others. The body is small, obconic, tajjering 

 rapidly backward to the origin of the caudal fin, where it becomes 

 very small, and continues to taper to the very slender posterior end. 

 The median dorsal angle of the mantle-edge projects fai- forward, as 

 a broad angular lobe; lateral angles rounded and not prominent. 

 Caudal fin relatively large, as compared with the body, broad-ovate 

 in outline, widest near the middle, tapering backward to an acumin- 

 ate, slender tip; very broadly rounded laterally, narrowing abruptly 

 anteriorly; the anterior lobes are small, rounded, and project only 

 sliohtly forward beyond the insertions. Siphon large, with a well- 

 formed valve, far back from the orifice ; dorsal bridles rudimentary. 

 Connective cartilages on the base of the siphon, broad-ovate, ear-shaped, 

 with two rounded prominent lobes projecting into its concavity, one 

 ])osterior, the other ventral, so that the pit is three-cornered (fig, \b). 

 The corresponding connective cartilages of the mantle consist of 

 two Yjits, separated by a prominent, triangular tubercle (fig. Ic), 

 Head large, in proportion to the body, tapering backward from the
