Oreinus. INDIAN CYPRINID^. 345 



We are indebted for our knowledge of this species to Mr. Griffith, who 

 found it in the Monas, and other rivers in different parts of Boutan, between the 

 elevation of two, and five thousand feet. It may occur higher, but Mr. Griffith 

 remarks, that in vallies above five thousand feet though fine clear streams are 

 common, yet fishes of any kind do not occur in them, and the natives assured 

 the Mission to which he was attached, that no fish existed at such elevations. 



The lower jaw is short and strong, composed of two deep bony limbs 

 firmly soldered at the symphysis, and covered with a thick cartilaginous 

 integument, similar to that which forms the same part in Gonorhynchus 

 2)etrophilus ; it is probably used as in that species for scraping confervoid 

 plants from the surface of the rocks. The intestines are more capacious, 

 but not quite so long as in the Gonorhynchs. Mr. Griffith remarks that though 

 this species delights in rising above the surface yet it will not take flies.
