considerably beyond the end of the body on each side, but are united 

 to its extreme tip, leaving a distinct notch beyond the end of the 

 tail. Each half of the caudal fin, taken by itself, is somewhat trian- 

 gular in form, with the angles rounded, or rather it is between semi- 

 circular and triangular, the length longitudinally being decidedly 

 greater than the distance from the base to the lateral border. 



The specimen above described is 27™"' long, from the end of the 

 body to the front edge of mantle, above ; length, from end of body 

 to base of dorsal arms, 34"""; breadth of body and head, 12""°; 

 breadth across caudal fin, 18™"'; length of caudal fin. 9"^"' ; length of 

 third pair of arms, 20™"'; length of tentacular arm, 67'""'.

Body large, stout, swollen, well rounded posteriorly, longer than 

 broad ; integument entirely smooth and soft, but not flabby ; fins 

 large, not very prominent, most so in front of the center, thick, soft, 

 and fleshy, colored like the body ; the line of attachment extends 

 from near the front edge of the mantle to about the posterior fifth 

 of the body, the anterior end being more dorsal than the posterior ; 

 the front end of the fin is free at base and projects forward con- 

 siderably beyond the edge of the mantle in a broad, rounded lobe; 

 the outer edge of the fin forms a very broad, even curve, narrowing 

 backward and closely adherent to the body posteriorly. The front 

 dorsal edge of the mantle extends forward in the middle region in a 

 very obtuse angle, and receding in a broad, sinuous curve behind the 

 eyes, it advances again below the eyes, and recedes to form a broad 

 ventral notch below the siphon. The head is very large, as broad as
