1909. These are the only two specimens taken in Peninsular Siani, 

 which is the northern limit of its range. 



The species ranges from Borneo and Sumatra northward through 

 the mountains of the Malay States to Trang, Peninsular Siam. 



It may be distinguished from all other species occurring in Siam 

 by having the upper surface of the tail red, a little lighter than the 

 back; below it resembles A. s. cara. 



A. temminckii has been made a form of A. mystacalis, of Java, by 

 some recent authors, a species to which it is only related generically. 

 A. mystacalis has the exposed surface of the tail above metallic 

 purple while in A. temminckii it is nonmetallic red, and there are 

 other differences. 



AETHOPYGA DABRYH DABRYII (Verreaux) 



Nectarinia ddbryii Verreaux, Rev. Mag. Zool., p. 173, pi. 15, 1867 (Szechwan). 



One female, summit of Doi Sutep, December 15, 1928; one female, 

 Khun Tan, September 8, 1930; one adult male and one immature 

 male, Doi Nangka, November 4, 11, 1930. 



The immature male taken on Doi Nangka, November 4, 1930, is 

 in a plumage resembling the female, but more yellowish on the belly; 

 some red feathers of the adult plumage are coming in on the back, 

 wing coverts, sides of head, and breast. 



The first specimen recorded from Siam was taken at Khun Tan by 

 Count Gyldenstolpe.^^ Since then it has been taken at Chiengmai ^* 

 and Doi Sutep,^° 5,500 feet, and Chiengdao ^' by de Schauensee. 



This is a common breeding bird in Szechwan and Yunnan, China, 

 and it has been taken in northwestern Tonkin, northern Laos, north- 

 ern Siam, and Burma as far south as Muleyit. Wliether it is resident 

 in Siam or only a winter visitor is open to question. Deignan ^^ 

 reports that it occurs on Doi Sutep in the cold weather. In a large 

 series of the form in the United States National IVIuseum from western 

 Szechwan and western Yunnan, there is only one specimen taken in 

 winter. This seems to show that the majority must move farther 

 south. 



From below the form resembles somewhat A. nipalensis angkanensis, 

 but the red of the chest comes right up to the color of the throat, and 

 the throat and pileum are a shining violet-purple instead of dark 

 green. A. n. angkanensis has a narrow yellow band across the chest 

 below the throat patch. There are numerous other differences, 

 but the above will suffice.
