18 PROCEEDINGS OP THE NATIONAL MUSEUM vol. 70 



A male from the Taipeishan district, Shensi, April 21, in the 

 United States National Museum (237709) has the white frontal band 

 much wider than any in the Yunnan series, but whether this is indi- 

 vidual or not it is impossible to say. One male and two females 

 from the Langbian Peaks, South Annam, taken in mid- April, cer- 

 tainly represent a distinct form. They are more of a russet brown 

 above; the throat is slate gray, not blackish (in the male) ; and the 

 white frontal band is reduced to almost the vanishing point. This 

 form has been named Siphia strophiata fuscogularis Baker. ^* 



70. DIGENEA TRICOLOR CERVINIVENTRIS Sharpe 



Digcnea cerviniventris Sharpe, Cnt. Birds Brit. Mus., vol. 4, 1879, p. 460 

 (Manipur Hills). 



Four males and two females from various stations in the Likiang 

 Mountains, 12,000 feet, April 27, June, July, and September. 



One of the above females has a broken bill, which caused me to 

 overlook its position and send it to Outram Bangs for identification. 

 He writes that the single female in the Museum of Comparative 

 Zoology from Washan Mountain, Szechwan, has rusty spots at the 

 ends of the greater wing coverts, while in the one sent him they are 

 plain. This is a sign of immaturity. The above two females are not 

 alike. One is lighter above, has rusty spots at the ends of the greater 

 wing coverts, and the tail lighter and more uniformly colored than 

 the other. It is probably not fully adult. 



71. NILTAVA SUNDARA DENOTATA Bangs and Phillips 



Niltava sundara denotata Bangs and Phillips, Bull. Mus. Comp. Zool., 

 vol. 58, no. 6, 1914, p. 280 (Mengtsze, Yunnan). 



A good series of adults and immature from various stations in 

 the Likiang Mountains, 9,500-12,500 feet, April-August. 



The series of males shows quite a little variation, the mantle 

 varying from a shining indulin blue to blackish violet-gray with 

 little blue sheen and the lower parts from mars yellow to a much 

 lighter hue. 



The only typical specimen of sundara available for comparison is 

 like the indulin-backed Yunnan male, but I prefer to follow Bangs ^^ 

 lor the present. 



There are two immature males, taken in July and August, re- 

 spectively. The August specimen much duskier than the other and 

 evidently younger. Both have acquired the blue tail and wings 

 of the adult, however.
