198 SOME CHINESE VERTEBRATES. 



COLOEUS NEGLECTUS (Schlegel). 



One old female, Tachienlu, western Szechwan, 10,000 feet altitude, July 20, 

 1908. 



This specimen is rather larger than any in a series of five in the collection 

 of the Museum of comparative zoology from near Pekin. Its wing being, 240 

 mm. long, as contrasted with 231 mm. in the largest of the Pekin skins. Tachien- 

 lu is also well beyond the known range of C. neglectus and very probably 

 more specimens would show that a large race of the Black jackdaw occupies 

 this region as well as a large race of C. dauuricus. We, however, hesitate to 

 make such a separation on a single specimen. 



COLOEUS DAUURICUS DAUURICUS (Pallas). 

 Three adults, one male and two females, Ituhsien, Hupeh, February. 



COLOEUS DAUURICUS KHAMENSIS Bianchi. 



Six specimens, both sexes, including four adults and two young, Tongolow, 

 and Tachienlu, western Szechwan, 10,000 to 12,000 feet altitude, July, and 

 August. 



This fine large form, originally described from Kham, Tibet, is easily dis- 

 tinguished from true C. dauuricus not only by greater size, but by the slightly 

 different shade of its belly. Bianchi (Ann. Mus. St. Petersb., 1903, 8, p. 11) 

 first recorded the form under a nomen nudum, C. major, and three years later, 

 when describing it, Bull. B. O. C., 16, p. 68, used another name, C. khamensis. 

 Sharpe, however, in the Hand List, gives both names, apparently overlooking 

 the fact that they apply to one and the same form. 



NUCIFRAGA HEMISPILA MACELLA Thayer & Bangs. 



Bull. M. C. Z., May, 1909, 52, p. 140. 



Two specimens, an adult male, the type, from Hsienshanhsien, December 

 11, 1907, and an adult female from Tachienlu, western Szechwan, September 23, 

 1908. 



This form is only slightly different from the Himalayan bird, true hemispila. 

 It is, however, smaller and has a shorter and thicker bill, but the pronounced 

 character of the white spotting in the Chinese bird does not hold good when 

 compared with a large series of Indian skins.
