THE BIRDS OF NORTHERN THAILAND 501 



applied to the Thai specimen ; its condition of molt, however, renders 

 measurement of the wing meaningless. The validity of saturatus is, 

 in any case, not yet established. 



bradypterus thoracicus thoracicus (biyth) 



Himalayan Gray-breasted Bush Warbler 



Dlunieticola] thoracica Blyth, Journ. Asiat. Soc. Bengal, vol. 14, 1845, p. 584 



(Nepal). 

 Tribura thoracica thoracica, Greenway, Bull. Mus. Comp. Zool. 1940, p. 187 



(Doi Aug Ka). 



The sole Thai record for the present race is based upon a female 

 taken by the Asiatic Primate Expedition on Doi Ang Ka, 4,300 feet, 

 March 3, 1937. 



Griswold, the collector, has noted that his specimen had the irides 

 light brown ; the maxilla gray ; the mandible flesh ; the feet and toes 

 flesh. 



According to Yen (Orn. Monatsb., vol. 41, 1933, p. 17), this sub- 

 species is differentiated from B. t. przevalskii only by having the 

 rufescent-brown of the crown concolorous with that of the mantle, 

 rather than darker. 



Griswold's bird, which I have examined, matches extraordinarily 

 well a female of thoracicus from Mount Omei in southwestern 

 Szechwan. 



BRADYPTERUS THORACICUS SHANENSIS (Ticehurst) 



Shan Gray-breasted Bush Warbler 



Tribura thoracica shanensis Ticehurst, Ibis, 1941, p. 318 (Maymyo, Upper 



Burma). 

 Dumeticola thoracica thoracica, Riley, U. S. Nat. Mus. Bull. 172, 1938, p. 422 



(Doi Langka). 



A male collected by Smith on Doi Langka, May 2, 1931, and an 

 unsexed bird taken by me on Doi Suthep, 3,300 feet, March 23, 1937, 

 are unquestionably of Ticehurst's race, with the description of which 

 they agree in every particular. 



On my last visit to Doi Suthep, at the boggy area below the Phra- 

 that (which had been explored by me periodically over a number of 

 years), I found for the first time, March 23, 1937, a gathering of 

 small brown warblers concealing themselves among the entangled 

 sedges. It proved to be impossible to shoot them from a reasonable 

 distance, and the two specimens obtained were too badly injured to 

 be preserved otherwise than as mummies. One of these examples is 

 listed above, while the second belongs to the next following species; 

 both are probably merely rare winter visitors to northern Thailand. 



Smith's bird of May 2 is in prenuptial molt.
