BIRDS FROM SIAM AND THE MALAY PENINSULA 315 



SITTA CASTANEA NEGLECTA Walden 



Sitla neglecta Walden, Ann. Mag. Nat. Hist., ser. 4, vol. 5, p. 218, 1870 (Karen 

 Hills, Toungoo District, Burma). 



One male, Doi Angka, December 2, 1928; one male and one female^ 

 Meklian, February 6, 1932; one male, Khonka Valley, January 19, 

 1933; one female, Doi Hua Mot, August 30, 1934. 



The range of this form extends from Muleyit Mountain, Tenas- 

 serim, through the eastern liill ranges of Burma to western and north- 

 ern Siam, Cambodia, and Laos. 



S. c. cimiamoventris has been recorded from northern and eastern 

 Siam,** but presumably there must be some error, as two races would 

 hardly occur in the same territory unless at different elevations in the 

 mountains. 



Chasen and Kloss*^ record S. c. neglecta from the Raheng district, 

 western Siam. Deignan*° took one on Doi Sutep, 1,800 feet, in 

 June; and Mr. Aagaard*^ took a single male on the summit of the 

 same mountain later; De Schauensee" took three males and a female 

 at Metang and says that it was found only in lowland jungle where the 

 trees reached a good height. 



SITTA EUROPAEA NAGAENSIS Godwin-Austen 



Sitta nagaensis Godwin-Austen, Proc. Zool. Soc. London, 1874, p. 44 (Naga 

 Hills). 



One male, Doi Nangka, November 20, 1930; one male. Pang Meton 

 (Doi Nangka), May 5, 1931. 



The form ranges from the mountains south of Brahmaputra, Chin, 

 and Cachin Hills to northern Siam, and it has been reported from 

 southern Annam, but specimens from tliis region may not be the same. 

 Two males from Dalat, southern Annam, in the United States Na- 

 tional Museum are more grayish below, the rufous of the flanks is 

 lighter, and they are paler above than the Siamese specimens. The 

 Langbian Peaks region is rather isolated from the normal range of the 

 form. 



De Schauensee*^ found S. e. nagaensis common on the summit of 

 Doi Sutep and less so farther down. Deignan^^ found it common on 

 the same mountain from 4,500 feet to the sumirdt and saw a pair car- 

 rjdng food into a nest hole in May at 5,500 feet. De Schauensee" 

 on his third expedition again secured it on Doi Sutep and Chiengdao 

 and states it occupies a zone above that at which Sitta magna is found..
