BIRDS FROM SIAM AND THE MALAY PENINSULA 459 



Wing, 60-63 mm. The immature male here recorded differs from 

 the adult in having the pileum, upper neck, and upper mantle buffy 

 brown. The female is described as having the whole upper plumage 

 rufous-olive, more rufous on the forehead; upper tail coverts bright 

 ferruginous; tail dark brown, tinged strongly with ferruginous; chin- 

 throat, and breast pale, bright orange-chestnut; remainder of lower- 

 parts, dull white. 



The species ranges from Sikkim to eastern Bengal, Chin, and 

 Kachin Hills to northern Siam. 



The above specimen, which has been previously recorded,^' is the 

 first record for Siam, so far as known. 



MUSCICAPULA MELANOLEUCA MELANOLEUCA BIyth 



Aluscicapula melanoleuca Blyth, Journ. Asiat. Soc. Bengal, vol. 12, p. 940, 1843 

 (Nepal, Darjeeling). 



One male and one female, Doi Nangka, November 3, 1930, April 23, 

 1931; one male. Pang Meton (Doi Nangka), May 5, 1931; one male, 

 Doi Hua Mot, August 17, 1934. 



This form has been recorded by de Schauensee ^° and by Deignan " 

 from Doi Sutep as M. melanoleuca westermanni. Later, from speci- 

 mens taken on the same mountain by Mr. Aagaard, Chasen and 

 Kloss ^^ say that the females show conclusively that Doi Sutep birds 

 are not the Malayan westermanni. This is not surprising. 



The range of this form is from Garhwal, Nepal, Sikkim to the ex- 

 treme east of Assam and south to northern Siam, Yunnan, Laos, and 

 Tonkin. 



The females of this form have a brownish wash on the upperparts; 

 not clear slaty-gray as in westermanni of the Malay Peninsula.

Two males and three females, Nakon Sritamarat, September 18-21, 

 1926. 



I have had only one female of G. m. modiglianii Salvadori from 

 Banka for comparison. It is a slightly lighter yellow below; the lores 

 have little or no white or gray; along the sides of the neck from 

 the bill to the jugulum there is a dark line separating the yellow of the 

 breast from the color of the upperparts. G. m. pedoralis is a little
