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",

from a fish stomach, was taken at station 2115, off Cape Hatteras, in

These Transactions, vol. v, p. 349, pl. 38, fig. 1; pl. 46, fig. 6, 1881. 
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
