[Vol.. VIII 



The only tortoise in this Hst {Nicoria^ tricarinata) is one of a 

 small group of more or less terrestrial Chelonia that occur both in 

 Chota Nagpur in Peninsular India and in the northern part of 

 Assam but apparently not in any intermediate locality. It is, 

 however, evident that we know as yet very little about the distri- 

 bution of the Indian land-tortoises. 



The genera of lizards and snakes that are known to occur in 

 the foot-hills N. of the Brahmaputra and E. of Bhutan are for the 

 most part widely distributed. Only one appears to be endemic, 

 viz. the new genus Aproaspidops, which is allied to the Burmese 

 genera Trirhinopholis^ and Plagiopholis.^ The genera Blythia and 

 Ptyctolaemus are characteristically Assamese , ^NhiXo^ Pseiidoxenodon , 

 Japalura and Draco are restricted to the damper parts of the Orien- 

 tal Region, the last-named being a characteristically Malaysian 

 genus also found in S. India, while the two first are essentially 

 continental in distribution. The genus Salea only occurs in the 

 foot-hills E. of Bhutan, in Lower Burma and in S. India, being 

 thus almost analogous in its range to the Ranid genus Micrixalus. 



If we separate out the 42 species in the list into geographical 

 groups as was done in the case of the Batrachia (p. 34 aniea) we 

 find that the following percentages can be calculated : — 



I. Species of wide distribution in the Hima- 

 layas, Assam, Burma and Indo-China 

 or Malaysia . . . . . . 16= 38% 



II. Species of very wide general distribution 6 = 14%

 Jahrb. Jena, igcg, suppl. x, p. 494, point out that by the strict letter of the law of 

 priority the name of this genus should be Geoemyda.
