The species marked with an asterisk are found also in the plains 
of Lower India. 
It is evident from the lists given that we intend to establish two 
subzones for the Amphibio-fauna. In the parts below 2400 feet the 
Reptiles are entirely identical with those of the plains ; there is not 
one species which indicates that we are at the foot of the gigantic 
wall which separates the Palearctic from the Palzotropical region, 
and the total absence of Crocodiles appears to be the only, but im- 
portant, sign of a coming change. Several other Reptiles gradually 
disappear: Gecko verus, Uromastix griseus, the true Tree-snakes of 
green colour, Rana tigrina, Emyda punctata, and finally Lycodon 
aulicus. In the upper portion of the zone appear two new Frogs, 
but they are merely representatives of species found in the lower one 
and in the plains, namely Dicroglossus representing Oxyglossus, and 
Rana liebigii, replacing Rana tigrina. Barycephalus begins here, 
and, although a genus peculiar to the Himalaya, it belongs to the 
family of Agamide, which is chiefly East Indian. The upper limit 
of this zone is remarkably distinct, and indicated by the simultaneous 
disappearance of one-third of the species found within its extent 
(Calotes versicolor, Simotes russellii, Tropidonotus quincunciatus and 
stolatus, Ablabes collaris, Daboia elegans, Dicroglossus adolfi, Rana 
liebigit).
