The greatest depth, which is at the anterior end of the first dorsal, is 3^ in the 
length without the caudal. 
The length of the head is nearly half the total without the caudal, the proportion 
being ii : 24. 
The eye is large, it is a quarter the length of the head and is longer than the 
longest part of the interorbital space. 
The mouth is oblique, the posterior end of the maxilla nearly reaches to a verti- 
cal through the centre of the eye. 
The length of the snout is slightly less than the diameter of the eye. The lower 
jaw projects beyond the upper. The symphysis of the lower jaw is very prominent. 
The nostrils are in front of the upper half of the eye and are much nearer the eye than 
the end of the snout. The anterior of the two nostrils is the smaller and is placed at 
a lower level than the other. The posterior margin of the operculum has two thin 
flexible points, the upper one being the smaller. The lower is formed by a prolonga- 
tion of the suboperculum and is supported by a third somewhat stronger point, which 
is the true posterior angle of the opercular bone. The preoperculum has a double 
border but is not serrated. 
There is a well-marked pseudobranch. The gill-rakers are numerous and flat- 
tened but not acutely pointed. 
There are small villiform teeth on the premaxillæ, palatines and vomer. The 
teeth of the lower jaw are larger than those of the upper. There is a pair of large 
canine teeth in the upper jaw and a pair at the symphysis of the lower jaw. 
The deciduous scales are very large and stout, they overlap one another by about 
three-quarters of their diameter, they are ctenoid, but some of the scales, especially 
those below the eye, have inconspicuous serrations or none at all.
