tance across, from angle to angle of the upper jaw, 
eight inches; the tip of the lower jaw projects nearly 
two inches in front of the upper. The intermaxil- 
lary bones are capable of being protruded nearly an 
inch beyond the maxillaries, and are armed with a 
single row of small pointed teeth upon each side, 
and two rows of much larger teeth in their centre ; 
one of these rows upon the edge, the other, within 
and beneath, very incurved ; upon the upper jaw, at 
its tip, isa space of one and a half inches, destitute 
of teeth ; on each side of this space, is one quite 
large tooth, and a second, much smaller ; about half 
an inch outside of these, a single row of eight or 
ten teeth, the three or four first of which, are much 
the largest. On each side of the pharynx, are three 
rows of sharp incurved teeth, about a line in length, 
resembling spines ; these rows are arranged directly 
above each other, and are double. The lower jaw 
has a single row of numerous, very sharp teeth, 
some of them half an inch long; the tongue has a 
broad, bony, triangular plate, upon each side, armed 
with two rows of teeth on each side, which are 
turned toward the throat. The distance from the 
margin of the upper jaw to the eye, is equal to the 
distance between the eyes. Several spines are ob- 
servable upon the head ; two just back of the snout, 
on each side; a bifurcated one over the middle of 
the eye, and =R similar one at its posterior an- 
gle; a small one in a line back of these, at the poste- 
rior portion of the head. A spine pointing forward, 
is situated at the angle of the jaws, and three straight 
Spines are seen back of this. The eyes are neatly
