Female. Body rather short, tapering backward, subacute posteriorly ; front 

 edge of mantle advancing somewhat in the middle, and forming an obtuse angle ; 

 considerably emarginate beneath. Caudal fin small, short, thin, each half nearly 

 semicircular, attiiched subdorsally, posterior end 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, behind the eyes, minute, with a small, erect, cla- 

 vate, fleshy process from the skin. Arms long, tapering, equal to the length of 

 head and body combined ; 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 cir- 

 cular, 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. Ten- 

 tacular 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 

 verruc£B, their centre or anterior half pale ; the border, or posterior half, dark 

 purplish brown ; upper surface of body with much fewer and smaller scat- 

 tered verrucae ; a circle of the same around the eyes ; inner surfaces of sessile 

 arras and buccal membranes chocolate-brown, tentacular arms lighter; suckers 

 pale yellow, with a light brown band. Caudal fin white, translucent. Iris, in 

 the preserved specimens, brown. Gills with the free edge brown, and a brown 

 line on the outer edges of all the laminae. Total length to end of lateral arms, 

 133 mm. ; to base of arms, 67 mm. ; mantle, 51 mm. ; length of fin, 17 mm. ; 

 breadth of fins, 24 mm. ; of body, 20 mm. ; diameter of eyeball, 16 mm. ; length 

 of dorsal arms, 58 mm. ; of second pair, 67 mm. ; of third pair, 68 mm. ; of ven-
