rest. A row of small tubercular suckers, ranged singly or 

 alternating two by two extends for about .six inches along the 

 stalks of the tentacles ; and minute serrate suckers also cover 

 the tip of the club, beyond its expanded portion. Sessile arms 

 stout, three-cornered, tapering to slender tips, each bearing two 

 rows of globular suckers, having a small, oblique opening, and 

 few blunt teeth. The ventral arms are united together, near the 

 base, by a web, which also unites to the main web, in the median 

 plane. A narrow web, arising from the outer angles of the 

 arms, also unites all the arms together for a short distance above 

 their bases. Beak with very sharp black tips ; a broad mem- 

 brane, rising into six prominent angles, surrounds the mouth. 

 Outer surface of head and arms covered with large, very slightly 

 raised warts or tubercles, which are dark blue, with a whitish 

 centre; a circle of them surrounds the eyelids. Color, between 

 the warts, purplish brown, with dark brown spots and reddish 

 specks; well and inner surface of arms uniform dark reddish 

 brown; suckers yellowish white; tentacles light orange brown. 

 Length of tentacles, 24 to 25 in.; of arms, 1, 14 in.; 2, It

 rounded in outline.
