The horny layer, which is so common inside of the lips of the 

 Schizothoracince., is still perceptible in the fishes of this genus, but 

 in many of those of the plains takes on the character more of a thin 

 cartilaginous than of a horny covering. The snout has sometimes a 

 deep depression across it as observed in Discor/nathus. The fins 

 frequently increase in height and length more rapidly than do the 

 proportions of the body ; in adults the upper edge of the dorsal fin is 

 often more concave than in the young. The largest species are found 

 near the coldest hills, pointing to their probable. Palaearctic origin. 

 In some species having the least number of dorsal rays, the lips are 

 much thinner than in the typical Labeos ; should such have only 

 t\vo barbels these are maxillary, whereas in Cirrhina they would 

 be rostral.
