A SCIENTIFIC EXPEDITION TO TEMENGOH., Pe 
variety of mouse deer were fairly common but trapping proved 
unproductive though one species of rat of the mueller: ero) 
certainly new to the peninsula-was secured. 
No species of very special interest are included in this 
list, which serves to show that with very unimportant . excep- 
tions the fauna of the Temengoh valley is the same as. that: of 
the rest of Perak. It may be noted, however, that several 
species, which in Batang Padang and Selangor are rarely met 
with below 3000 feet occur at altitudes which do not exceed 
1000 feet, a fact which may be due to the immediate proximity 
of large and lofty mountain masses. Such species are 
Pyrotrogon erythrocephalus 
Hemipus picatus 
Otocompsa flaviventris 
Sertlophus rothschildi 
Anthothreptes rhodolaema takes the place of the commoner 
_A. malaccensis as has recently been found to be the case in the 
more northerly state of Trang. The yellow headed Chloropsis 
is however, CO. icterocephala and not CU. chlorocephala and the 
small barbet Mesobucco, though not typical M. duvauceli, the 
southern form, appears to be nearer to that race than to UM. 
cyanotis of the northern states. The woodpecker Gecinulus 
viridis usually rather rare in Perak, though it occurs sparingly 
on the main range as far south as scuthern Selangor, where- 
ever there is much bamboo, was not uncommon in Temengoh.
