as offshoots of tho big Hi malayan chain. 



Whoii tho low-lying countries at a latcr period wore submerged by wa1< i. the Hi- 

 malayan elements still retained fcheir position up to the present time. 



Lower Siarn and especially those parts which lay south of the Islhnius of K ra viz. 

 abont Lat. N. 10° 30' is inhabited by a Fauna in which the Malayan element is strongly 

 pronounced but even north of Kra this same Malayan element may be traced though 

 mixed with immigrants from the north. Curiously enough the Malayan forms seem to 

 extend further north on the eastern side of the mountain ridge than on the western one 

 and several forms have been obtained further north on the eastern or ttiai ide 



The course of this is still open to question, as the types of the landscape are almost 

 the same. The reasons may, however, possibly be the diffcrent meteorological condi- 

 tions. The western side of the Malay Peninsula is much more exposed to the full violence 

 of the monsoon than the eastern side and this may prevent several delicate species to 

 force their way north.
