The proboscis on the snout exhibits considerable variation 

 and it is on this account that so many different species have been 

 recorded or described from South India. Having examined nu- 

 merous specimens of this form, I am convinced that all these 

 should be referred to G. stenorhynchus. The extent of the snout 

 does not depend upon the age or the sexual maturity of the 

 specimen as is shown bv the collection before me. The specimens 

 with a comparatively small proboscis have been referred to B. 

 jerdoni {nee Day) both bj' Annandale and Rao ; but on dissection 

 some of them have been found to be full of eggs. 



The air-bladder is rather characteristic and provides a good 

 specific distinction. In a ripe female specimen 12 cm. in length, 

 the following are the measurements of the bladder : — 



Length of anterior chamber .. .. . 5'o mm. 



., ,, posteror ,, ... 3'5 mm. 



Greatest diameter of anterior chamber .,, 3'8 mm. 



,, ,, ,, posterior ., ... ... 2'o mm. 



The bladder is provided with a thicker coat ; its posterior 

 chamber is swollen anteriorly and drawn out into a fine process 

 posteriorly, the walls of which are thickened.

 Of the five specimens procured by Dr. N. Annandale from the 

 Inle Lake and the He-Ho stream, two are ripe females, one ripe 

 male and two immature males. The type specimen of G. graveiyi 

 is the mature male and differs considerabl}' from the female speci- 

 mens, but the presence of two young males serves to a certain ex- 

 tent as a connective link between the two forms. In the male the 

 mental di.sc is better developed, the mouth is considerabl}' behind 

 the tip of the snout and consequently the labial fold is more ex- 

 tensive, the pectoral fins are longer than the head, the snout 

 possesses an indistinct proboscis and the head and body are some- 

 what depressed with the chest almost naked, while the female 

 lacks all these characters.
