emarginate and free from the tip of the body, but not extending much 

 beyond it. Head large, flattened above. Eyes 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, well rounded, 

 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 verrucse, their center or anterior half 

 pale, the border or posterior half dark purplish brown ; upper surface 

 of body with much fewer and smaller scattered verrucse ; 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 laminae

 mantle, 51 mm ; of fin, 17 ram ; breadth of fins, 24 mm ; of body, 20 mm ; diameter 

 of eyeball, lG mm ; length of dorsal arms, 5S mm ; of second pair, 67 mm ; of 

 third pair, 68 mm ; of ventral pair, C0 mm ; breadth of dorsal arms at base, 

 5 mm ; of lateral, G mm ; diameter of largest suckers, 1.2 mm .
