THE BIEDS OF MONGOLIA ETC. 171 



49. Phyllopnbuste plumbeitarsa, Swinh. 



Phyllopneuste coronata, Midd. nee Temm. 



Is very abundant in the Kan-su mountains, where it generally confines 

 itself to the wooded clifi^s. It appeared there in the middle of May ; but the 

 snow, which fell after its arrival, destroyed a great many, and I found dead 

 ones, and some others so weak that we caught them with our hands. 



50. Phyllopneuste xanthodryas, Swinh. 



According to Swinhoe this is the largest Warbler that occurs in China ; 

 It is closely allied to Ph. borealis, Bias., but differs from it in size and in 

 other points enumerated by Swinhoe (P. Z. S. 1863, p. 296). Measurements 

 of the male— length 5''-4, width 8'', gape O'^'SS, wing 2''-77, tail 2''-17, 

 tarsus 0''-72, middle toe 0''-42, hind toe 0''-24. 



We found it only in the Kan-su mountains, where it inhabits the wooded 

 districts and is rather scarcer than the preceding species, although common 

 enough. 



51. Phyllopneuste borealis. Bias. Penochka severnaya, 



Phyllopneuste eversmanni, Middendorff, Sibirisehe Reise_, t. ii. p. ii. pi. xvi. figs. 1-3. 



Tolerably common in the mountains of S.E. Mongolia, especially at 

 Muni-ul. In Northern Ala-shan, about the beginning of May, we saw 

 several migrating about the steppes ; and here also this lively and clever bird 

 has the same habits as in other localities. It is scarce in Ussuri country ; 

 and I cannot say if it breeds there or not. 



52. Phyllopneuste fuscata, Blyth. Penochka temnaya. 



Phyllopneuste sibirica, Middendorff^ Sibirisclie Reise^ t. ii. pi. xvi. figs. 4-6. 



Like the preceding species, it is very common in S.E. Mongolia, but
