AKT. 7 BIKDS FROM YUNNAN AND SZECHWAN, CHINA EILEY 15 



47. STREPTOPELIA CHINENSIS FORRESTI Rothschild 



Streptopelia chinensis forresU Rothschild, Nov. ZooL, vol. 32, p. 293, 1925 

 (Tengyueh, Yunnau). 



One male and one female, Likiang Mountains, 10,000 feet, Yun- 

 nan, January-February. 



48. OENOPOPELIA TRANQUEBARICA HUMILIS (Temminck) 



Columta humilis Temminck, Nouveau recueil de planches colorizes d'oiseaux, 

 liv. 44, pi. 259, 1824 (Bengal, Luzon). 



Six males and one female, Tatsienlu. 9.500-10,000 feet, Szechwan, 

 May. 



The five adult males in the above series have been compared with 

 seven adult males from Luzon. On the whole the Chinese series 

 appears to be slightly darker, but there are individual birds that 

 are so close that they can be distinguished only with difficulty. The 

 Luzon birds have slightly shorter wings. The seven Luzon birds' 

 wings measure: 130.5-140 mm. (136.9) ; while the five Chinese birds' 

 wings measure: 139.5-142 mm. (140.7). On the whole the Luzon 

 and Chinese series are too close to separate by name. 



49. COLUMBA HODGSONII Vigors 



Columl)a liodgsonii Vigors, Proc. Zool. Soc. London, 1832, p. 16 (Nepal). 

 Two males, Muli Valley, 9,600 feet, southwest Szechwan, June. 



50, COLUMBA LEUCONOTA GRADARIA Hartert 



Columha leuconota gradaria Haetebt, Nov. Zool., p. 85, 1916 (Snngpan, Szech- 

 wan). 



Three males and three females, southwest Szechwan (Mount 

 Konka, 16,500 feet, June ; Ronapien, Shouchu Basin, 14,500 feet, Au- 

 gust; Briiolo-kong Valley, 13,000-15,900 feet. May; Chengtze, 14,500- 

 15,900 feet, May). 



Specimens from Yunnan and from the southern border of south- 

 west Szechwan have the mantle somewhat darker than birds from 

 farther north, but agree with northern birds in having lighter, grayer 

 heads than the typical leuconota from Kashmir. On the whole the 

 Yunnan specimens are better placed with the northern race, though 

 somewhat intermediate. 



51. COLUMBA RUPESTRIS AUSTRIMA Riley 



Columha rupestris ausirina Riley, Proc. Biol. Soc. Washington, vol. 43, p. 133, 

 1930 (Chengtze, Szecliv/an). 



Three males, Chengtze, 14,500-15,900 feet, Szechwan, May. 

 Besides the above, the United States National Museum contains 

 three males and three females from Szechwan (TatsienlHi or vicinity.
