334 Mr. H. E. Dresser's Notes on 



so that immature birds of T. mystacinus and T. atrigularis 

 cannot with certainty he distinguished. I may also mention 

 that of hotli species wc obtained many more females than 

 males during winter in the gardens of Chimkent and Tash- 

 kend near the Syr-Darja, and it will therefore be necessary, 

 before it can be positively stated tliat T. mystacinus is a good 

 species, to obtain a series of summer-killed specimens of the 

 adult bird as well as nestlings, and careful observations should 

 be made during the summer season."

 Horizontal range. Occurs during passage in districts I. and 



II., and during winter in district III., but is everywhere very 

 rare. 



Vertical range. Is met with during passage and in winter 

 in districts 1 and 2. 



In a few short notes on this species (p. 119) Severtzoff re- 

 marks that the bird described and figured by Radde (Reis. im 

 Slid, von Ost.-Sib. taf. viii.) is T. nauinanni, and not T. rufi- 

 collis, and adds that whereas T. ruficollis always has the flanks 

 grey, T. naumanni has them marked brownish or rufous, and 

 in old males the flanks are rufous, like the throat, which, con- 

 necting with the entire flanks, forms one continuous rufous- 

 coloui'ed area over the throat, breast, and sides, whereas in 

 T. ruficollis the throat, and a circular patch covering the breast 

 above, are rufous. To this I may add that in T. naumanni 

 the inner webs of the quills are pale rufous to nearly two 

 thirds of their length from the base, whereas even in very 

 old examples of T. ruficollis the inner webs are only very 

 faintly tinged witli pale rufous buff" towards the base of the 

 feathers.
