 is stated by Sumichrast to inhabit also the Tierra Caliente; and Anolis 

 nannodes Cope, which the same authority says ranges from the Tierra 

 Caliente into the Alpine district. The water-snake Natrix rhombi/era 

 Hallowell may occur in the Austroriental district, but this needs con- 

 firmation. 



The Austroccidental district is inhabited by a number of peculiar 

 species, together with some whi(;h occur in the other two districts of 

 the Toltecan subregion. One peculiarity of this district is the jtoverty 

 in Batrachia and the absence of IJrodela. The peculiar species are the 

 following:
