from southeast Yunnan is not a well-marked race; the back is 

 browner and the breast a much lighter yellow than M. i. jerdoni. 

 I should amend the key to read as follows : 



1. Back olive 2 



Back Mars brown ^ ignotincta 



2. Breast mustard yellow jerdoni 



Breast primrose yellow mariae 



Stresemann '- has recently named a race, Mmla ignotincia sini 

 from the Yaoschan, Kwangsi, but I have seen no specimens of it.

 129. LIOTHRIX LUTEUS YUNNANENSIS Rothschild 



Liothrlx luteus ynnnanensis Rothschild, Nov. Zool., vol. 28, p. 42, 1921 (Shweli- 

 Salwin Divide, Yunnan). 



Three females, Ndamucho, 14,000 feet, Yunnan, October. 



When a report was published ^^ on Doctor Rock's first collection 

 from Yunnan and Szechwan, the United States National Museum 

 possessed an inadequate series of LiothHx luteus luteus^ and my re- 

 marks based upon a comparison of the present race with it are mis- 

 leading and erroneous. Since then a large series of L. I. luteus has 

 been acquired from Szechwan, and the differences between it and 

 Z. I. yunnanensis are not so pronounced as appeared at first. Instead 

 of being more highly colored, L. I. Tjunnmiensis is actually paler 

 below, but above there is little difference. L. I. yunnanensis is a 

 larger bird, but the chief difference between it and L. I. luteus lies in 

 the color of the outer webs of the base of the outer primaries ; in the 

 latter they are much deeper, not the reverse as formerly stated. 



In L. I. yunna^nensis the yellow outer margin to the inner prima- 

 ries is interrupted near the middle, while in L. I. luteus no such inter- 

 ruption occurs. L. I. yunnanensis is a well-marked race.
