Scales of moderate or small size. Dorsal fin "without osseous ray, 

 ■with more than nine branched rays, commencing somewhat in ad- 

 vance of the ventrals. Snout obtusely rounded, the skin of the maxil- 

 lary region being more or less thickened, forming a projection beyond 

 the mouth. Mouth transverse, inferior, with the lips thickened, 

 each or one of them being provided with an inner transverse fold, 

 which is covered with a deciduous horny substance forming a sharp 

 edge, which, however, does not rest upon the bone as base, but is 

 soft and moveable. Barbels very small, two or four, the maxiLary 

 barbels more or less hidden in a groove behind the angle of the mouth. 

 Anal scales not enlarged. Anal fin very short. Pharyngeal teeth 

 uncinate. 5.4. 2 — 2 .4.5. Snout generally more or less covered

The skeleton of Labeo resembles much that of Barhus; every part 

 of it is solid, and well ossified. Occipital crest prominent, firmly 

 united with the neural spines of the anterior vertebrae, and streng- 

 thened on each side by a lower lateral crest. A series of irregular 

 broad interneural elements runs from the occipital crest to the origin 

 of the dorsal fin, giving much strength to this part of the vertebral 

 column. The lower apophyses for tlie attachment of the air-bladder 

 and ossicula auditus are very strong, and have their base dUated and 

 honeycombed. The mandible is feeble, styliform, with its anterior

 * To give an idea on what characters these so-called genera are founded, we 

 may mention that, for instance, Valenciennes distinguishes Lahco from Rohita 

 by entire (not fringed) lips, but subsequently describes an entire series of species 

 of Lahco with fringed lips. Probably several species are described by him imder 

 different names, once as Labeo, and again as Rohita. Bleeker cannot have ex- 

 amined L. niloticus (the type of Lahco, Cuv. !), or he would have found it agree- 

 ing better with- i)foJ'M/«w« (Blkr.) than witb Labeo (Blkr.)&c.
