Base of the dorsal fin longer than that of the anal and more than / 4 of the length, of the body. Length of 
the pectoral fins less than that of the ventral, than either the preabdominal length or the postabdominal , and than 
half the length of the maxillaries, which is about half the distance betiveen the dorsal fin and the tip of the snout 
or a little greater. Longitudinal diameter of the eyes less than half (< 2 / 5 ?) of the postorbital length of the 
head, which is more than 3 / 5 of the entire length thereof. Least depth of the tail more than 8 % of the length 
of the body or than 2 / 5 °f the greatest depth of the latter. Scales of the lateral line slightly, if at all, larger 
than those of the body in general.
