described as British India with Burma and all other depen- 

 dencies,, and with the addition of Ceylon Baluchistan, Kash- 

 mir, Ladak, and all Cis- Himalayan States being included, and 

 Afghanistan, Tibet Proper, China, Siam, and the Malay 

 Peninsula south of Tenasserim excluded. 



The following comparison of the number of species de- 

 scribed, from within the limits adopted in the present work, 

 in Giinther's ' Reptiles of British India 'with those enumerated 

 in Theobald's Catalogue and in the present volume will serve 

 roughly to indicate the additions to our knowledge of the 

 Reptilia and Batrachia of India in the last quarter of a 

 century. As already noticed, one subfamily of Snakes, 

 the Hydrophiinre, was omitted by Theobald, 



Giinther, Theobald, Boulenger, 



39 130 



In cases where the numbers have been reduced the reduc- 

 tion is due to the union of species formerly supposed to be 

 distinct. The additions in the present volume are much more 

 numerous than the preceding comparison indicates.
