A. E. V err ill — North American Cephnlopods. 
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 arras. Length of dorsal arms, 
27 mm ; of second pair, 44; of third pair, 46 ; of fourth pair, 37; of 
tentacular arms, 120 ; of club, 16 mm . 
Two typical specimens were obtained off Martha’s Vineyard, at 
stations 1031 and 1033, in 255 and 183 fathoms; one of doubtful 
identity, at 994, in 368 fathoms, by the Y. 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 “ Fish 
Hawk,” this season. 
Chiroteuthis lacertosa. sp. nov. (See p. 299.)

Plate LYI, figures 1-1/. 
A nearly complete male specimen of a Chiroteuthis , lacking only 
the tentacular arms and the distal portion of the left ventral arm, 
was received after the preceding pages were put in type. The 
stumps 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. 1-lfi. It appears to be a new species, and is very 
distinct from C. Bonplandii. The sessile arms are very large in 
proportion to the head and body, and the ventral arms are much 
larger than any of the others. The body is small, obconic, tapering 
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 far 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 
slightly 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 
posterior, the other ventral, so that the pit is three-cornered (fig. U). 
The corresponding connective cartilages of the mantle consist of 
two pits, separated by a prominent, triangular tubercle (fig. le). 
Head large, in proportion to the body, tapering backward from the
