bution of animals. Forms belonging to the Palearctic fauna extend 
from the north into the mountains, as the Indian species do from 
the south, and we may infer that there exists a great difference be- 
tween the reptiles inhabiting the northern parts of the Himalayas 
and those found on its southern slope ;—a difference, which, for the 
present, is merely pointed at by Phrynocephalus tickelit, Trigonoce- 
phalus afinis and Bufo vulgaris, obtained by MM. von Schlagintweit 
in Tibet. The Himalayas, situated on the border between the Pale- 
arctic and the Indian regions, offer the same variations in their 
fauna as the Sahara, which separates the Palearctic region from the 
/Ethiopian.
