106. LIOPTILA DESGODINSI (David and Oustalet) 



Sihia desgodinsl David and Oustalet, Bull. Soc. Philom. Paris, ser. 7, 

 vol. 1, 1877, p. 139 (Yer-ka-lo). 



A fine series from: Heshwe, 10,000 feet, April 30; between Bayi- 

 wua and Heshwe, 10,000 feet, May 2; Likiang Mountains, 8,500- 

 14,000 feet, April-August; Ngaza, east of Dyinaloko Mountain, 

 9,000 feet, June; Hofuping Mountains, Mekong Valley, November; 

 Tseh Chung Mountains, Mekong Valley, November; Youngning 

 Forests, February; Yunnan-Szech wan border, February. 



The above series does not appear to differ from specimens from 

 Szechwan. A young bird not long from the nest was taken in Au- 

 gust. It does not differ from the adult, except in size. 



107. SiVA CYANOPTERA WINGATEI Grant 



Swa imngatei Grant, P>nll. Brit. Orn. Club, vol. 10, 1900, p. 38 (Yunnan 

 City). 



One female, Yiinlung, March 22. 



This specimen is considerably lighter brown above and much 

 lighter below than any specimen in a series of five females from 

 Suif u, Szechwan ; it is also more streaked on the head. 



108. SIVA STRIGULA YUNNANENSIS Rothschild 



Siva striffula yunnanensis Rothschild, Nov. Zool., vol. 28, 1921, p. 40 

 (Likiang Range, Yunnan). 



A fine series of both sexes from: Between Likiang and Tuinakou 

 (Yangbei Koad), 10,000 feet. May 16; between Likiang and Gan- 

 haitze, 10,000 feet. May 19; Likiang Mountains, 10,000-13,000 feet, 

 April-August; Lameko Mountain, north of Lashipa, July; Tseh 

 Chung Mountains, Mekong Valley, October; Hofuping Mountains, 

 Mekong Valley, November; Mountains near Yangtza, Mekong Val- 

 ley, November; Mill Forest, southwest Szechwan, February. 



The birds taken in the fall have the whole lower parts, even the 

 throat, deep yellow, the back olive drab. In spring and summer 

 taken examples the back becomes deep olive gray; the pileum much 

 brighter and more restricted; the throat grayish white, only the chin 

 remaining yellow ; the foreneck grayish ; and the yellow of the lower 

 parts much lighter and more restricted. In both styles the throat is 

 barred with black. There are also other slight differences. The two 

 plumages are very distinct and the change must take place at a 

 rather early date, as it has been already assumed by a specimen taken 

 as early as April 21, in rather unworn plumage; in the summer, 

 Avhen Avear and fading have set in, the differences are still further 

 accentuated.
