3. H. LiNEATUs\ Guv. Sf Val. Western G-hauta and Malabar 

 coast to Ceylon. 



4. H. PANCHAX^, Ham. Buch. Orissa, Lower Bengal, Burma, 

 Siam, Andaman Islands to the Malay archipelago. 



Amongst the CTPRiNiDiE we know of thirty-five genera repre- 

 sented in the fresh waters of India, Burma, and Ceylon ; of these, 

 twenty-six belong to the true Carps {Cyprinina), and nine to the 

 Loaches (Cobitidina). 



Of the Cyprinina, or true Carps, including the Homalopterina, 

 we find the following : — 



1. HoMALOPTERA^, V. Hasselt. This genus is distributed through 

 some of the hilly districts of the Himalayas, also the western 

 Ghauts and Neilgherries in the Madras Presidency ; and examples 

 are likewise found in Java and Sumatra. 



2. PsiLORHTNCHUS, McClelland. Hill-streams and rivers in 

 Bengal and Assam. 



3. Disco GNATHUS*, SecTcel. Bivers, more especially mountain- 

 streams, of Asia and Abyssinia, extending throughout India, 

 Ceylon, and the Tenasserim provinces. 



The next and four succeeding genera consist of a division of 

 Carps which are strictly residents of hilly regions of the Hima- 

 layas, but some descend to the plains. 



4. OEEiisrus, M'Clelland. This genus extends from the Hel- 

 mund river and Jellalabad in Afghanistan,along the Himalayan and 

 contiguous ranges of mountains to at least the confines of China. 

 They only descend a short distance into the rivers of the plains, 

 and are absent from the level plateaux on the summit of those 

 mountains. 



5. ScHizoPTGOPSis, SteindacJiner. Cold regions of the Hima- 

 layas about the head- waters of the Indus, Tibet, and Eastern Tur- 

 kestan, where the rivers are snow-fed. In short, the Schizothora- 

 cina (if we exclude the Himalayan Oreinus) are confined to cold 

 regions, or at least to localities possessing snow-fed rivers, many
