1918.] G. A. BouLENGER & N. Ak^nandale : liana tigrina. 67 



I have one more remark to make, and that is on Wiegmann's figure 

 of R. rugulosa. I have re-examined this figure, and, with all deference 

 to Dr. Annandale's opinion, I can only repeat my statement that I 

 regard the snout as pointed, as much so as in Dr. Annandale's figures 

 of R. tigrina,^ and the web between the toes incomplete and deeply 

 notched.^ It must be borne in mind that the types of R. rugulosa and 

 R. vittigera have been compared by no less an authority than the late 

 Professor Peters, and pronounced by him to be specifically identical 

 {Mon. Bed. Ac. 1863, p. 78). 



1 Dr. Annandalc mentioned as one of the characters of his B. rvgulosa the less pointed 

 snout as compared to R. tifjrina, and that is why I draw attention to the shape of the 

 snout in Wiegmann's figure. I therefore request a comparison of the latter with the 

 heads figured on Plate V of the Mem. As. Soc. Btng., Vol. VI. 



2 I have not said that the feet "' are meant to be webbed in exactly the same way as 

 in the figure of R. vittigera on the same plate," and I know how greatly the extent of 

 the web varies in R. cancrivora (see my remarks under that heading). 1 was alluding to 

 Dr. Annandale's definition on p. 122 of his paper, where R. rvgvlosa is stated to have the 

 feet almost fully webbed and the web very little emarginate.
