tical with that of the W. Himalayas. 
The typical form of D. lamta is a dweller in rapid-running 
streams, in which its labial sucker is of great use in enabling it 
to adhere firmly to the bottom or sides. In the fountains 
round the Lake of Tiberias, however, the race rufus lives for 
the most part in still water. If a man puts his bare feet 
into the water the fish frequently clings to them by means 
of the sucker and apparently attempts to suck or nibble 
at the skin. Owing to the fact that the mouth is ventral,

and pigeons that were thrown into the water fastened to
