So far as the genera mentioned in the foregoing list are con- 

 cerned, its most striking features are the number of species of 

 Ixalus included and the fact that the allied Burmese genera Chirix- 

 alus and Phrynoderma are also represented. Until recently the 

 genus Ixalus, which abounds in Burmese and Malay forms, was 

 not known from any part of the Himalayas or Assam, and even 

 now only one species has been proved to exist in the Himalayas, 

 west of Bhutan, namely Ixalus annandalei, Boulenger.* It is pro- 

 bable that another species (/. asper) also occurs in the Nepal foot- 

 hills, but, even so, the genus is characteristically non-Himalayan.* 

 Chirixalus and Phrynoderma have hitherto been monotypic genera, 

 as the former still remains, and have only been recorded from the 

 Karin Hills. 



The occurrence of the S. Indian genus Micrixalus in the Abor 

 foot-hills is exactly parallel to that of the lacertilian genus Salea, 

 a species of which has recently been described from the adjacent 

 Dafla country. 



We may analyse the list further as regards species in the 

 following manner, dividing them into seven geographical groups : — 



A. Species apparently endemic in the foot-hills 



E. of Bhutan 



B. Forms found in the Himalayas, Assam and 



Burma 



C. Species of very wide distribution
