Plate XLIII, figures 1, 2. 



Body small, very short, depressed, broadly rounded posteriorly, 

 broader than long. Fins very long and narrow, their length consid- 

 erably exceeding the breadth of the body, in alcoholic specimens ; 

 toward the base they are much thickened and supported by an inter- 

 nal cartilage, which does not appear to be continuous with the thin 

 cai'tilage that extends across the body, just behind the fins. The 

 fins are inserted just behind the eyes, and their breadth is somewhat 

 greater in the middle than at the base; they narrow but little toward 

 the tip, which is obtusely rounded. Head large and broad, exceed- 

 ing the body in size and thickness in the preserved specimens, the 

 greatest thickness being at the base of the arms. Eyes small, lateral, 

 very far apart, the distance between them being, on the dorsal side, 

 more than twice their diameter. Siphon short, conical, with a broad 

 base. Gill-opening small, simple, only a little broader than the base 

 of the siphon. Arms long, thick and strong, the dorsal ones a little 

 longer than the others, which decrease successively to the ventral 

 pair, which are, however, but little shorter than the third pair. The 

 arms are thick and well rounded, especially on the basal portion, 

 with the inner surface elevated along the median line, on which the 

 suckers are arranged in a simple row ; the marginal angles are but 

 slightly indicated, and bear a row of small, slender, tapering cirri, 

 alternating with the suckers, which are very small, urceolate, strongly 

 elevated above the surface of the arms, and of a light yellow color, 

 in strong contrast with the chocolate-brown of the arms. The dis- 

 tance between the suckers along the middle portion of the arm usually
