BLACK-MOUTHED DOGFISH. 
suddenly bent opposite the origin of the caudal fin. Colour 
light brown on the head and along the back; on each side 
two rows of ocellated spots — one row beginning at the side 
of the neck and continued along the side of the back ; the second 
row commencing behind the eye and passing along the upper 
side of the belly, becoming obsolete near the ventral fins. 
These rows are separated by numerous irregular spots, which 
however, assume somewhat of a straight direction; the fins 
and hinder part of the back are finely barred and clouded 
with various tints of brown and yellow; the mouth dark- 
coloured within. 
This example was a male, and was ornamented with livelv 
colours; but since then I have obtained one in which the 
colour was so diluted as to appear almost of a uniform grey; 
although on close inspection the usual markings could be dis- 
cerned. It was also a male, and its pale colour may be explained 
by its emaciated condition, for it appeared as if in a state of 
starvation. The length was a little beyond two feet, which 
therefore I suppose to be the ordinary size, but the caudal 
portion of the body behind the second dorsal fin appeared 
longer than in the former example.
