as that from Yunnan or will later be found to differ and need 

 naming. 



The type of Dryonastes herthemyi came from the mountains of 

 northwest Fokien, probably Kuatun. It is rather surprising to find 

 a closely related form in the high mountains of northwest Yunnan, 

 more than 1,000 miles from the type locality of the species. Nda- 

 mucho is south of Liitien on the Yangtze-Mekong Divide. The 

 United States National Museum contains an adult female of Dryon- 

 astes herth^myi from the type locality, and the Museum of Com- 

 parative Zoology has loaned me a pair from near the same place ; the 

 three specimens are quite uniform. The three specimens from north- 

 west Yunnan are also quite uniform and differ from the Fokien bird 

 as described. The three specimens from Yunnan measure: Wing, 

 120-128 mm. (124) ; tail, 125-132 (128) ; culmen, 20-22 (20.7). Two 

 females and one male from Fokien measure: Wing, 116-118 (116.8) ; 

 tail, 122-126 (123.5) ; culmen, 22.5-23 (22.Y). 



LaTouche *" makes herthemyi a race of poecilorhynchus of For- 

 mosa, but I do not think he is right in doing so. They have both 

 been derived from the same stock, but now are so distinct that it is 

 misleading to treat them as forms of the same species. 



112. POMATORHINUS RUPICOLLIS SIMILIS Rothschild 



Pomatorlimus ruficollis similis Rothschild, Nov. Zool., vol. 33, p. 261, 1926 

 (Teugyueb, Yunnan). 



Three males and four females, northwest Yunnan (Likiang Moun- 

 tains, January-February and September; mountains of Yungning, 

 November-December; upper slopes of the Fuchuanshan, 10,000- 

 12.000 feet, September; Weihsi, 8,000-9,000 feet, September; 

 Ndamucho, 14,000 feet, October) ; one female, southwest Szechwan 

 (Muli Valley, 9,500 feet, June). 



This is quite a distinct race, Saccardo's umber above ; quite differ- 

 ent from PomatorJdnus mficollis eidos from Yangtze Valley farther 

 east, which is strongly tinged with rufous above and has a smaller 

 bill. The latter occurs in two ventral color phases : one in which the 

 chest streaks are rufous and the other in which they are brownish 

 olive, but no matter which phase the specimen is in, the upperparts 

 are strongly tinged with rufous. P. i\ similis is quite uniform in j 

 series and does not vary much ; specimens from the Mekong Valley I 

 are Saccardo's umber above, while those from the Likiang Moun- 

 tains are light brownish olive. Just where the ranges of similis and 

 eidos meet it is impossible to say. The United States National 

 Museum has the latter from the Szechwan border south of Suifu, 

 Mount Omei, and the vicinity of Suifu, but not from farther west.
