it is armed ; they are separated from each other superiorly by a broad and 
deep furrow, widest in front. The teeth of both jaws are numerous, and those 
of the lower jaw, generally, larger than those of the upper. Towards the an- 
terior extremity of each intermaxillary bone they are arranged in two or three 
rows ; those of the hinder row, which are much the largest, are cylindrical, 
slightly curved, and directed backwards ; the others, which are of the same 
form, and have the same kind of curve, are much weaker and shorter ; the 
anterior margin of the lower two-thirds of each bone is armed with a series of 
short, delicate, cylindrical teeth, each slightly incurvated, and placed at regular 
distances the one from the other. Besides the teeth on the intermaxillaries, 
there are a few others situated on the outer edges of the palatal bones, and 
also two or three in a cluster at each angle of the vomer anteriorly. The 
palatal teeth are disposed in a row, and the two or three, near the anterior 
extremity of each row are longest. The teeth of the lower jaw are moderately 
slender, cylindrical, closely set, nearly straight, and very unequal in regard 
to length, some measuring an inch, others not more than a quarter of an 
inch. The eyes are large, directed outwards, and situated about half an inch 
below the outline of the upper surface of the head, nearly directly over the 
angle of the mouth ; the pupils are almost circular. The branchial openings 
are rather narrow, and situated in the axilla of the pectoral fins ; the latter are 
rather broader at the extremity than the base, and the former is somewhat 
truncated. The body is subcylindrical. The dorsal and anal fins are small ; 
the hinder edge of each is square, and the former is situated rather in 
advance of the latter. The caudal fin is somewhat fawn-shaped, and its pos- 
terior edge is truncated ; all the fins are soft and fleshy. The sides of the body, 
close to the belly, and the edges of the lower jaw, are fringed with flat and 
short dentated filaments, varying from a quarter of an inch to an inch in 
length ; they are irregularly scattered on the side but disposed in a single row 
on the jaw. On the anterior and upper surface of the head, in the course of 
the mesial line, there are two long, slender, spinous tentacula ; the hinder 
one, which is a little in front of the eyes, the longest ; two others, of a like 
description on the beginning of the back, immediately over the pectoral 
fins, the anterior one the longest. Length of the head 11 inches, of the 
body, exclusive of the caudal fin 13 inches ; greatest width of head about 
3 inches behind the eyes 8^ inches ; height at hind head 6 inches. Length 
of the pectoral fins 3§ inches ; of the dorsal 4 inches ; of the anal 3 inches ; 
of the caudal 4J inches. Rays of the pectoral fins 16 ; of the dorsal 7 or 8 ; 
of the anal 7 ; of the caudal 12s.
