76 MR. C. BODEN KLOSS ON 
N. W. of Raheng, W. Siam, 1500, ft. [No. 2632/CBK.]. Collected by 
Mr. K. G. Gairdner on 13 March 1917. Orig. No. 399. 
Diaynosis. Slightly darker than R. rajah finis* from 8. E. Siam 
and with shorter nasals: these are more truncate posteriorly and 
always, apparantly, fall decidedly short of a line joining the front 
extremities of the orbital spaces ; in jinis the nasals are nearly always 
protracted backwards beyond such a line, and the ends are more 
rounded or pointed: in the present race the posterior ends of the 
premaxillaries are also less oblique. This form is duller above than 
R. rajah surifer (Miller) of Peninsular Siam. 
Specimens examined. Six from the type locality and Me Taw, 
1500 ft., closely adjacent [ Orig. Nos. 864, 376, 398, 405.], and another 
from the Pa Wa Gorge, N. Siam [ Orig. No. 228], all collected by 
Mr. Gairdner.
