or freshly preserved specimens examined since I have had the advantage 

 of readino- Dr. Boulenser's notes. 



Rana tigrina, Daudin. 



I have little to add to Dr. Boulenger's notes on this frog except in 

 reference to its geographical distribution. 1 will, however, discuss the 

 form and structure of its inner metatarsal tubercle in dealing with Rana 

 crassa.

Geographical distribution. — I have made a careful examination of 

 the specimens in the Indian Museum referred to in my original paper 

 [op. cit., pp. 125-126) and find no reason to change my opinion as to the 

 great majority of them. The form certainly occurs not only in North- 

 ern India, but also at many places in the south of Peninsular India, 

 as well as in Assam, Burma and Yunnan. Its range thus overlaps that 

 of both R. crassa and R. rugulosa. Apparently it differs in habits from 

 both these forms, being feebly or not at all possessed of powers of 

 burrowing. 



Rana rugulosa, Wiegmann. 



The name of this species depends entirely on the interpretation of 

 Wiegmann's figure. ^ I have great hesitation in differing from Dr. 

 Boulenger on a point of interpretation, but cannot agree with him that 

 the snout is represented as being pointed ; indeed, Wiegmann says 

 " Schnautze stumpf." Nor can I agree that the feet are meant to be 

 webbed in exactly the same way as in the figure of Rana vittigera on the 

 same plate. I have no doubt, therefore, that the types of my Rana 

 burkilli, which are in very good condition, and also the series of speci- 

 mens sent to me by Dr. Malcolm Smith from Siam are specifically iden- 

 tical with the specimen that Wiegmann selected to be figured as typical 

 of his R. rugulosa.
