Leuciscus Storerianus. Head small, quadrangular, flattened 

 between the eyes, angulated above the nostrils, which are separated 

 by a longitudinal sulcation. Nose obtuse, somewhat conical, pro-

 Eyes oblong oval ; iris silvery and slightly gilt on inner margin ; 

 pupils black. Operculum and prceoperculum smooth, lustre bright, 

 silvery. Mouth diagonal, and, when closed, the lower lip is nearly 

 concealed beneath the snout. 



Body elongated, slightly compressed laterally. Back rises rap-

 more gradually and uniformly. Abdomen expands beneath the 

 pectoral fin, and continues of the same size to the vent ; it then 

 rapidly diminishes to the tail. Lateral line straight, except that 

 near its base it curves as high as the upper edge of the operculum. 



Dorsal fin elevated, trapezoidal ; caudal elongated, bilobed, with 

 the tip of each lobe acute ; anal fin falls short of the dorsal ; ven- 

 tral horizontal, and reaches to the vent; pectoral falcate, nearly

Length 8 inches ; head 1 3-8 inch ; tail 1 5-8 inch ; depth of 

 body at the commencement of the dorsal fin 1 5-8 inch. 



Color. Back and upper surface of body and head olivaceous ; 

 sides silvery and of a brilliant metallic lustre, with a brownish band 

 extending the whole length of the lateral line ; pectoral and ven-
