The height of the body is contained five times in the total length, 
the length of the head four times and a half. The head is very 
slightly convex superiorly, and the width of the interorbital space 
is contained twice and one-third in the length of the head. The 
upper lip is not thick. The angle made by the two mandibulary 
bones is an obtuse one. The cleft of the mouth is not quite half 
as deep as broad (between the angles of the mouth) . The maxillary 
is entirely covered by the prseorbital. Eyes hidden behind a broad 
adipose membrane ; nostrils rather distant from each other, the pos- 
terior being in the middle between the anterior and the orbit. The

vertical fins are not scaly; the first two dorsal spines are half as 
long as the head ; the pectoral extends to about the eighth scale of
