Indian and Malayan Amphibia and Reptilia. [No. 2, 



limbs of the type form ; on the other hand, however, a very slight 

 webbing, distinct from all others ! 



I hope to be able to give illustrations of all these forms, as soon 

 as I may be placed in possession of more extended materials which, 

 I trust, will be sufficient either to confirm the present determination, 

 or to shew that what I pointed out as varieties are in reality to be 

 considered as distinct species. I can now only repeat that, whatever 

 anxiety some herpetologists may feel regarding the consistency 

 of the species in question, I cannot view those insular forms, on 

 comparing them with hundreds of specimens which I myself 

 collected in the Sundarbansj Arracan, E an goon and down the 

 Tanasserim coast to Penang, as anything else but local varieties of 

 one and the same species. I shall now only add the actual measure- 

 ments of the principal forms.

The varieties from Moulmein and (i) Nicobariensis are almost
