emarginate and free from the tip of the body, but not extending much 
beyond it. Head large, flattened above. Hyes very large, with simple, 
thin, free, circular lids, without any sinus. Openings of the ears be- 
hind the eyes, minute, with a small, erect, clavate, fleshy process of the 
skin. Arms long, tapering, equal to the length of head and body com- 
bined ; the lateral pairs are equal; the dorsal and ventral nearly equal, 
somewhat shorter than laterals; suckers deeper than broad, wellrounded, 
? laterally attached by slender pedicels ; horny rings with smooth, circu- 
lar, thin edges, except on the 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 ventral 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 verruce, their center or anterior half 
pale, the border or posterior half dark purplish brown; upper surface 
of body with much fewer and smaller scattered verruce; a circle of the 
same around the eyes; inner surfaces of sessile arms and buccal mem- 
branes chocolate-brown; tentacular arms lighter; suckers pale yellow, 
with a light brown band. Caudal fin white, translucent. Iris in the 
preserved specimen, brown. Gills with the free edge brown, and a 
brown line on the outer edges of all the laminz
