Mouth medium, directed obliquely upward; lower jaw longer than the upper, which is short, narrow, and protractile. Teeth in the outer series larger, strongly hooked, pointed, broadened somewhat toward the apex; inner series very small, in bands, tricuspid as in Pwcilia; pharyngeal with a shoulder. Eye large, longer than snout, 3 in head. Fins small, excepting the caudal; dorsal smaller than anal and farther back, its origin about midway from occiput to end of caudal, nearly above the hindmost anal ray, 17 cv 18 scales from the head; anal origin midway between snout and end of caudal; farther forward on the male, between the vcntrals, and the fin is modified to form an intromit- tent organ about i length of entire fish; caudal deep, as long as head, rounded on hinder margin. Hcales large, median series on flank as wide as eye. Intestine short. Light olivaceous, yellowish or brownish, with 7 or 8 vertical bars of brownish, separated by light or silvery spaces of equal width, on the sides of the caudal portion, edges of scalea darker, the centers or median series more or less silvery; belly and lower surface of head silvery or golden; peritoneum black, showing through abdnominal wall; occiput dark; top of snout light; a dark line between anal and caudal; dorsal with a faint spot or group of puncticulations behind the middle near the base; other fins plain to dark tipped.
