Colour.— The upper and lateral parts of the head, together with the back 
and sides of the body and the fins yellowish brown ; the sides of the head 
posteriorly and the sides of the body lightest 5 the under suiface of the 
head, body, and pectoral fins pearl-grey, tinted with yellowish brown. The 
filaments disposed upon the sides of the body and edges of the lower jaws, 
dark yellowish brown ; the spinous tentacula on the head and anterior part 
of the back, light yellowish brown. Eyes greenish white, with a metallic 
lustre. Teeth amber-coloured. 
Form, &c. — Head very bulky as compared with the body, and posteriorly 
nearly as high as broad \ the outline, when viewed from above, is somewhat 
oval, and broadest behind. The upper surface of the head is much narrower than 
the under surface ; nearly flat and slopes gradually from the vertex to the muz- 
zle ; the sides are subvertical, or slightly convex, and diverge as they descend. 
The lateral boundaries of the upper surface of the head is distinctly defined 
by the angle which is formed by the junction of the upper surface and the 
sides, and posteriorly each of these lines of demarcation are armed with three 
short obtuse spines ; the foremost one is situated nearly over the eye, the 
second about two inches behind it, and the third at the hinder part of 
the vertex, considerably nearer to the centre of the head than the middle 
one, and not very distant from its fellow of the opposite side. The relative 
positions of these spines are well represented in the Plate. In addition to 
these there are two other spines of rather a stronger description ; but, like 
them, short and obtuse, one immediately behind the anterior and superior 
extremity of each maxillary bone, and rather below the line which marks the 
upper surface of the head (vide Plate). The gape is moderately large, but 
not very broad ; the opening of the mouth is directed obliquely upwards 
and forwards ; and the lower jaw projects considerably beyond the upper. 
The symphisis of the lower jaw is narrow, the rami are arched and gradually 
curved upwards, and the jaw, when viewed as a whole, has a triangular form, 
the symphisis constituting the apex. The intermaxillary bones form the an- 
terior edges of the upper jaw, and support the majority of the teeth with which
