50 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 70 



The single specimen from the last locality is a female and much 

 darker on the chest, ear coverts, and nuchal region than any others 

 in the series and may represent another race. 



The specimen I have listed above as the immature is quite distinct 

 from the adult. It is cream-buff below ; the chest crossed by a band 

 of black spots ; the throat with two narrow black lines from the chin ; 

 the nuchal and auricular region much lighter than in the adult ; and 

 the feet (in the skin) honey yellow instead of blackish brown. It is 

 quite a different looking bird from the adult, but if not the young of 

 this species, I do not laiow where to place it.

Mecistura vlnacea Verreaux, Nouv. Arch. Mus. Paris, vol. 6, Bull., 1870, 

 p. 39 (Ourato). 



One male and one female, Lashipa Plain, 8,500 feet, May 28. 

 This seems to be considerably south of the published range of this 

 form.

185. SITTA SINENSIS NEBULOSA La Toiiche 



Sitta europaea tiebulosa La Touche, Bull. Brit. Orn. Club, vol. 42, 1922, 

 p. 55 (new name for Sitia europaea obsciira La Touche, preoccupied; 

 Milati, Yunnan). 



A good series of adults: Likiang Mountains, 8,200-15,000 feet, 

 April-September; near Tsilikiang, Yangtze Valley, 5,000-6,000 feet, 

 May 17; between Ganhaitze and Yangtze Gorge, 9,000 feet, May 20; 

 mountains near Yangtza, Mekong Valley, November; Hofuping 

 Mountains, Mekong Valley, November. 



This series exhibits two phases of plumage. A dark phase, some- 

 what resembling Sitta s. smensis below but not near so dark, and a 

 light phase somewhat resembling Sitta nagaensis below but some- 

 what darker. The light phase were all taken April and May; the 

 dark phase in late summer and fall (one in May), so fading is prob- 

 ably the cause. The dark phase resembles Sitta s. sinensis but is 

 much lighter below, but a darker, clearer gray on the back and the 

 bill (in the skin) bluish at the base instead of yellowish.

Sitta yunnanensis Grant, BuU. Brit. Orn. Club, vol. 10, 1900, p. 37 (Wei-
