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 
petrophilus ; 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.
