46 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 80 



A good series from northwest Yunnan (Likiang Mountains, Jan- 

 uary-February, September, and October; summit of Yuli water- 

 shed, 13,000 feet. May; Ndamucho, 14,000 feet, October) ; two males 

 and three females from Szechwan (Muli Mountains, 10,000 feet, 

 June; Noon, east of Muli, 10,500 feet, August; Yanwekong Valley, 

 10,000-12,000 feet. May). 



This series compared with a small series taken at the same time 

 of the year from farther north in Szechwan is slightly darker on an 

 average, but there are individual specimens that seem to be identical. 

 It seems to me that the differences are too slight to recognize by name. 

 If Yuhina ampeUna Rippon is worthy of recognition at all. it will 

 have to be restricted to western Yunnan and the Burma border. 

 Rothschild ^^ says that some fresh unworn specimens of amyelhia 

 are almost sooty black, but he seems to be somewhat in doubt as to 

 the Yunnan bird from farther east. None of the above series is as 

 dark as one would be led to expect from his remarks. No specimens 

 are available for comparison from the type locality of amjyelina.

 August; Yulo, T.OOO feet, August; Shintsang, 11,000 feet, Septem-

All the phases of plumage, except the entirely black, are repre- 

 sented in the above series. Three of the specimens are dark neutral 

 graj^ above, the pileum shining black, the lowerparts a much lighter 

 gray than the back, the middle of the breast and the belly with white 

 markings on the feathers forming a line; two of the specimens are 

 getting a few white feathers on the forehead. All three are evi- 

 dently immature, assuming the first adult plumage; the two with 

 white on the foreheads taken in May, the other in September. Three 

 immatures with considerable of the brownish juvenal feathers still 

 remaining were taken in August. All three are molting into a black 

 plumage above; one into a black plumage below, but another into a 

 gray one below. All three, however, have the feathers of the center
