ALCIPPE NIPALENSIS EREMITA Riley 



Alcippe nipalensis eremila Riley, Proc. Biol. Soc. Washington, vol. 49, p. 25, 1936 

 (Kao Seming, Krat, southeastern Siam). 



One male and one female, Kao Seming, Krat, October 16, 1928; one 

 male and two females, Kao Sabap, 2,000 feet, November 16, 17, 1933. 



This series is similar to A. n. peracensis of the Malay Peninsula but 

 is lighter brown on the back and tail; the pileum a lighter gray; the 

 black line on each side of the crown and nape broader and a deeper 

 black; the under tail coverts and thighs much lighter; the feet (in the 

 skin) are deep grayish olive instead of tawny and the bill averages 

 larger. 



Two males and two females of A. n. peracensis measure: Wing, 

 64-65.5 (64.7); tail, 64-66.5 (65); culmen, 11-12 (11.7) mm. Two 

 males aud three females of A. n. eremita: Wing, 65-68.5 (66.7); tail, 

 59-65 (61.9); culmen, 12-13 (12.5) mm. A pair of paratypes of 

 A. n. annamensis: Wing, 58-63; tail, 61-64; culmen, 10.5-11 mm. 



The pair of A. n. annamensis differ from A. n. eremita in being paler 

 on the back and tail, the chest tinged with grayish, whereas in the 

 latter the throat is whitish and the chest light buff; the bill in anna- 

 mensis is smaller. It seems to be a good form and is probably con- 

 fined to the mountains of southern Annam. 



A. n. eremita is probably confined to the mountains of southeastern 

 Siam and Cambodia. 



Delacour and Jabouillc^^ record A. n. peracensis from southern 

 Laos. The record probably belongs to A. n. eremila. 



Birds of this form group are mountain-inhabiting, and there is a 

 long stretch of country between the range of A. n. peracensis and A. n. 

 eremita where the species does not occur. 



ALCIPPE POIOICEPHALA HARINGTONIAE Hartert 



Alcippe haringtoniae Hauteut, Bull. Brit. Orn. Club, vol. 25, p. 10, 1909 (Bhamo, 

 Upper Burma). 



Four males and one female, Khun Tan, October 28, 1929, Septem- 

 ber 6 and 9, 1930, and March 4, 1932. 



De Schauensee *^ took two males at Chieng Sen and says that it 

 replaces A. nipalensis fratercula in the lowland forests; on his third 

 expedition ^^ he took a small series at Chiengdao and Khun Tan and 

 changed his former identification from haringtoniae to magnirostris, 

 but without comparison. I likewise have no specimens for compari- 

 son, but the specimens before me do not agree with S. Baker's descrip- 

 tion of magnirostris J° The coronal stripes are blackish, and the chin 

 and throat are not whitish but the same color as the rest of the under-
