ventrals and midway between tip of snout and base of caudal, its height !§■ in head; anal, 
i, 7, its base If in head ; pectorals short, not reaching the ventrals ; ventrals quite short, not 
reaching vent; scales, 5-34-3, 15 before the dorsal; lateral line complete and but little 
decurved. Color, as given by Mr. Woolman, light brown above ; edges of scales above lateral
