Garra mullya is the most widely distributed species of the genus 

 in India: its range extends from Kathiawar, through the greater 

 part of the Central Provinces, to the whole of Peninsular India. 

 Consequent upon a wide range it shows a certain amount of 

 \-arialion. In some examples the disc is greatly reduced and its 

 free borders represented l)y a short fringe. In one example from 

 Bomba3% the paired fins are extremely small and show a stunted 

 growth. The forru is fusiform and the snout is almost smooth. 



Specimens of this species occurring in hill-streams are some- 

 what flattened and different looking. The air-bladder exhibits 

 considerable variation and in the hill-stream forms it is usually 

 reduced. The species seem to be still in process of adaptation to 

 hill-stream life. 



The following are the measurements of the bladder in a speci- 

 men from Malabar which is lo cm. in length without the caudal 

 fin:—
