24 PROCEEDINGS OF THE NATIONAL MUSEUM vol.77 



The United States National Museum has recently acquired a 

 good series of poor skins from Sungpan, Szechwan, the type locality 

 of the form. They seem to have shorter and straighter bills than 

 the Kansu birds, but apparently do not differ in color. Chihli birds 

 are darker than those from Kansu. Since the above was written, 

 Stresemann has named a race from Lanhukou, Kansu, Janthocincla 

 davidi funebris^^ and Bangs and Peters have described lanthocincla 

 davidi experrecta from the Richthof en range.^'^ 



96. TROCHALOPTERON ELLIOTII PRJEVALSKII Menzbier 



Trochalopteron prjevalsMi Menzbiee, Ibis, 1887, p. 300 (Kansu Mountains). 



Three males and 3 females, 120 miles south of Lanchow, July 30- 

 August 16; 1 young male not long from the nest, 10 miles further 

 south, September 13, and 1 female, 20 miles further south, September 

 10; 1 male, 15 miles northwest of Sining, Kansu, August 8. 



This is a desert mountain form of Trochalopteron eUiotii, much 

 lighter in color with little or no white edgings to the feathers of 

 the throat or black terminal or subterminal bars on the mantle. A 

 certain number of T. e. elliotii have the central rectrices gray, aniline 

 yellow only on the outer webs at the base, while two specimens of 

 T. e. prjevalshii in the above series have the central rectrices yellow,, 

 so this supposed character for separating the two races does not hold. 



In some of the August specimens of prjevalskii, the foreheads 

 and pileum have bleached out to a pale drab gray, almost white. 

 While this also happens with the more southern form to some ex- 

 tent, it is not near so pronounced, which was to be expected. 



97. lANTHOCINCLA MAXIMA (Verreaux) 



Pterorhmus maximus Verkeaux, Nouv. Arch. Mus. Paris, vol. 6, Bull., 1870,. 

 p. 36, pi. 3, fig. 1 (Mts. of Chinese Tibet). 



One male, 120 miles south of, August 14, and 1 male and 2 females, 

 140 miles south of Lanchow, September 10; 1 male, Choni, Kansu,. 

 August 22. 



The United States National Museum contains a large series of 

 this species from further south, mostly from northern Yunnan. 

 The southern birds appear to be somewhat darker and have a longer 

 wing than those from Kansu. The three Kansu males have a wing 

 136-143 ; four males from Yunnan, 143-150 mm.
