“ The height of the body is greater than the length of the head and 
equals one-fourth of the total length without the caudal; the distance 
of the naiie from the front margin of the jaw is contained 24 times in 
its distance from the beginning of the dorsal. The diameter of the eye 
equals the length of the snout, aud is about one-titth that of the head. 
Maxillary reaching nearly to the middle of the eye, its length contained 
34 times in that of the head; the supiilemental bone about half as long 
as the maxilla, aud its greatest width equals one-third of its length. 
The length of the mandible equals three-sevenths of that of the head, 
reaching to the hind margin of the orbit. The aiipendage of the ven- 
tral tin is less than half as long as the fin and nearly equal in length to 
the 7 scales immediately over it.” Eye 5 in head. Scales much smaller
