Scales of moderate or small size. Dorsal fin Avitliout osseous ray, 

 vrith more than nine -branched rays, commencing somewhat in ad- 

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

 lary I'cgion 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. Bai'bels veiy 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 

 with hollow tubercles. 



Presh waters of tropical Africa and of the East Indies. 



The slceleton oi Labeo resembles much that of Barbus ; every part 

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

 united with the neural spines of the anterior vertebra3, 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 the attachment of the air-bladder 

 and ossicula auditus are very strong, and have their base dilated 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 Labeo from Rohita 

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

 of Labeo with fringed lips. Probably sevei-al species are described by liim under 

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

 amined L. niloticK.s (the type of Labeo, Cuv. !), or he would have found it agree- 

 ing better with Moruliri.t (Blkr.) than with Labeo (Blkr.)&c.
