From six to seven, rarely eight, inches.


{Form). General form resembling that of the Dace, but more elongated: greatest depth exactly one-fifth of the entire length; greatest thickness about half the depth: ventral line more convex than the dorsal, rising rather abruptly posteriorly along the base of the anal fin: head contained five times and a half in the entire length: forehead flat: eyes large; their diameter very nearly one-third the length of the head: snout short; lower jaw projecting, ascending to meet the upper: lateral line descending in a sweep from the upper angle of the opercle till it reaches the middle of its course, thence passing off nearly straight to the caudal; above the ventrals its course is at just two-thirds of the depth: scales of moderate size, thin, finely striated, easily detached; number in the lateral line about forty-eight; above it seven and a half; beneath three and a half: dorsal entirely behind the middle; its greatest height about two-thirds of the depth; its length scarcely more than half its height; first ray only half the length of the second; second and third rays longest; the succeeding ones decreasing; the first two simple, the rest branched: anal commencing in a line with, or rather in advance of, the last ray of the dorsal; longer than in any of the preceding species of this sub-genus, and occupying half the space between the vent and the origin of the caudal fin; the first two rays very short; third and fourth longest, about equalling the longest rays in the dorsal; the first three simple, the others branched: caudal forked for half its length; the lower lobe of the fin a very little longer than the upper: pectorals shorter than the head, not reaching to the ventrals when laid back: ventrals shorter than the pectorals, considerably before the dorsal, and not reaching to the vent.

(Colours). Back olivaceous green; sides and belly bright silvery; the two colours separated by a well-defined line: cheeks and gill-covers silvery white: all the fins pale; the anal and ventrals nearly pure white: irides pale yellow.

Common in rivers, swimming in large shoals near the surface. Spawns in May and June. Food, principally insects.
