the side, slightly swollen around the mouth. Mouth of medium width, 
cleft to a vertical from the middle of the eye, rising forward ; maxillary 
tooth-bearing, widening backward, rounded on the hind margin, with a low 
ridge along the outside, forming about five sevenths of the mouth border; 
intermaxillary short, two fifths as long as the maxillary spreading out 
and forward. Teeth small, subconical, in single series on intermaxillaries, 
maxillaries, and dentaries ; a single larger tooth, like a small fang, at each 
side of the vomer. Eye very large, lateral, twice as long as the snout, five 
times as wide as the interorbital space on the skull, two fifths as long as the 
head. A sharp ridge from the angular up and forward to below the eye 
on the mandibles. Corner below the angular prominent. Four gills; 
lamelle short, narrow; rakers five plus fifteen, slender, longest two fifths 
as long as the eye; openings very wide; membranes not united, free from 
the isthmus. Opercles large, thin and membranous backward. Pseudo- 
branchiz well developed. The narrow groove on the skull between the 
eyes widens into a rounded concavity backward; forward at each side of 
it there is a shorter groove. Eight moderately long pyloric cxca. 
Dorsal origin twice the length of the head from the end of the snout. 
Anal origin below the twelfth or thirteenth ray of the dorsal. Ventral bases 
very little forward of a vertical from the first ray of the dorsal; fins reach- 
ing behind the vent. Vent below the middle of the dorsal base. Depth 
of the base of the caudal about half of that of the body; fin forked. 
Pectorals small, below the middle of the side. 
Scales large, broad, thin, flexible, deciduous; those of the lateral line 
half as broad as those in the series at either side of it.
