Body elongate, slightly compressed ; caudal pedicel rather slender, broad- 
ening at base of the fin. Head large, one third of length, without caudal ; 
crown broad, depressed and concave at occiput and snout, flattened in the 
middle. Snout large, broad, blunt, rounded, nearly twice as long as eye ; 
chin vertical. Mouth wide, oblique, cleft reaching below the lower level of 
the orbit. Teeth strong, in bands, numerous, hooked, subconical. Eye 
medium, about half the length of the snout, one sixth of that of the head, 
and three fifths of the width of the interorbital space. Scales of head and 
shoulders granular; a series of about twenty large vertebral scales, in front 
of the dorsal; scales of the lateral line larger than those on each side of it; 
belly scaleless. On young individuals all the scales are flat, thin, and con- 
centrically striate; the granulation and thickening appear first at the head 
then gradually extend farther back. Dorsal origin near half way from head 
to caudal; fin low, rounded on upper margin, third ray above origin of anal. 
Anal extending a little farther back than dorsal, in base and fin. Pectorals 
about the size of anal, reaching half way to the vent. Caudal broad, hinder 
margin concave, more deeply indented in the young. Specimen described 
ten and a half inches in length. 
Brownish on back, lighter on flanks, centres of scales lighter; white 
beneath ; fins clouded with brownish ; young with blotches and spots on the 
upper surface, and several series of small spots across dorsal and caudal.
