THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 163 



The two specimens recorded from the upper slopes of Khao 

 Nawng wove obtained on 23rd and 25th June 1913. Male and 

 female closely resemble each other ; but in the latter the scarlet 

 patches on the sides of the throat are only slightly developed. The 

 red occipital patch is much smaller than shown in Shelley's figure, 

 and the yellow tips to the feathers of the frontal red band are prac- 

 tically non-existent, as indeed is mentioned in Hume's original 

 description. 



Four birds (1 d~, 3 9) obtained on Khao Luang, 4,500 ft., 

 Nakorn Sri Tamarat, in March 1922, precisely agree with the two 

 from Khao Nawng. 



Possibly C. davisoni is only the fully adult C. incognita, 



which has precedence by three years. 



***** 



There are four other barbets that may possibly be found in 

 Peninsular Siam — all being birds with the general plumage green : — 

 Cyanops oorti (S. Mull.). 



Throat rich yellow, succeeded by blue ; a narrow frontal red 

 band ; crown pale yellow. 



This is only likely to occur on high elevations in the south. 

 It is elsewhere known from Sumatra and the mountains of the Brit- 

 ish portion of the Malay Peninsula, with an allied form, C. o. 

 annamensis, in the mountains of Annam. 



Cyanops ramsayi (Wald.). 



Throat yellow, succeeded by a broad silvery grey gorget, 

 forehead broadly red, crown bright yellow ; sides of the head silvery 

 grey. 



This also is only likely to be found at considerable elevations : 

 it is known from Karennee, North Tenasserim, North Siam, and the 

 mountains of Perak, Selangor and Pahang. 



Cyanops henricii (Temm.). 



Throat blue, without yellow ; forehead and superciliary stripe 

 rich yellow almost surrounding a blue crown.
