The only specimen from Assam, a female {Dicrurus leucophaeus 

 hopwoodi)^ available for comparison is a much darker bird both 

 above and below than any in the Yunnan series. Six males in the 

 series have a wing, 143-157 (147.5) ; and five females, 145-152.5 

 (148). Bangs ^' assigns three males from the same general region 

 to Dicrurus leucophaeus nigrescens, but remarks that they are large 

 birds. Rothschild ^^ also assigns specimens from northern Yunnan 

 to this race. The wing is considerably greater than that given by 

 Stuart Baker,^^ however.

236. CORVUS MACRORHYNCHOS INTERMEDIUS Adams 



Corvus intermedius Adams, Proc. Zool. Soc. Lend., 1859, p. 171 (Kaschmir 

 Dogshai, and Simla). 



One adult (unsexed but probably a male), Likiang Mountains, 

 12,000 feet, April 16: one adult male, Hofuping Mountains, Mekong 

 Valley, November. 



These have been compared with five males and four females from 

 Kashmir, and while they have slightly larger bills, 58 against 56- 

 57.5 (56.7), the differences are hardly enough to warrant subspecific 

 separation. 



Oorvus 7nacrorhy7ichos tibeto sinensis Kleinschmidt and Weigold ^^ 

 and Corvus coronoides Tnengtszensis La Touche ^^ are synonyms.
