A. E. Verrill — North American Cephalopoda. 
small suckers, toward the tips of the arms, in which the outer edge 
is divided into a number of small, narrow, blunt teeth. On the ven- 
tral arms, the suckers are much smaller. Basal web rudimentary; a 
narrow, thin, simple membrane along each side, outside the suckers. 
Tentacular arms rather slender, compressed, smooth at base, the ends 
absent. Color reddish brown. The ventral surface of the body, 
head, and arms is more ornamented than the dorsal surface, being 
covered with large, rounded verrucae, their center or anterior half 
pale, the border, or posterior half, dark purplish brown; upper sur- 
face of body with much fewer and smaller scattered verrucae; a cir- 
cle of the same around the eyes; inner surfaces of sessile arms and 
buccal membranes chocolate-brown, tentacular arms lighter; suck- 
ers pale yellow with a light brown band. Caudal fin white, translu- 
cent. Iris, in the preserved specimen, brown. Gills with the free 
edge brown, and a brown line on the outer edges of all the laminae.

Body elongated, tapering to a point, confluent with the caudal fin 
posteriorly. Caudal fin very large and broad, rhomboidal, occupy- 
ing about half the length of the body. Mantle fastened to the base 
of the siphon by an ovate, ear-shaped, elevated cartilage, on each 
side, fitting into corresponding deep, circumscribed pits on the base 
of the siphon. Siphon with a bilabiate aperture, an internal valve, 
and a pair of dorsal bridles. Eyes large, with round pupils; lids 
free, thin, apparently with a very small anterior sinus. Arms very 
unequal, the ventral ones much the longest. Suckers small, in two 
regular rows. Tentacular arms long and round, tapering to the tips, 
shaped like a whip-lash, without any distinct club; the distal portion 
is covered nearly all around with exceedingly numerous and minute 
suckers, which leave only a very narrow naked line along the out- 
side. Pen narrow and bicostate anteriorly, very slender in the mid-
