Similar to F. majalis in shape, but with longer snout and different color- 
ation. Back considerably arched above the pectorals. Head elongate, one 
third of length to base of caudal, subquadrate in transsection, crown flat or 
slightly concave longitudinally. Snout long, twice the eye, as wide as deep, 
slightly turned upward in larger individuals, blunt; chin steep. Mouth 
wide, oblique, lower jaw longer, upper protractile. Teeth conical, in bands, 
outer series longer; pharyngeal with a shoulder, median resembling molars. 
Eye medium, twice in the snout, one and one half times in the interorbital 
space, four and one half times in the head. Three series of scales below the 
eye on the cheek. Dorsal origin about midway from opercle to base of 
caudal, little forward of that of anal. Base of anal opposed to that of 
dorsal, not reaching as far forward, and hardly as far backward. On 
males anal and dorsal are more or less pointed and the former has a 
slight indentation on the outer border, behind the point. Anal rays 
longer than those of dorsal. Caudal deep, two thirds as long as head, 
truncate. 
Light olivaceous to yellowish, back darker, centres of scales lighter, sil- 
very to brownish on the flanks, white to yellow beneath. With eight to 
twenty narrow bars of brown across the flank. The following are either 
present or absent according to the individual or sex: a blackish spot at the 
upper angle of the opercle, cloudings or spots in the fins, a black spot at the 
upper end of the hindmost bar on the base of the caudal, a dark band 
across the hind edge of the caudal, and an ocellate spot on the hinder rays of 
the dorsal. Cheeks commonly silvery. Largest specimen six and one half 
inches in length.
