The two male specimens n:o 196 and 197 are probably 

 young specimens as they have very short bilis about 15 mm. 

 The bill of the female is 20 mm. Length of wing in the 

 adult 80 mm in the others resp. 79 and 76 mm. 



Taczanowski has recorded this Nuthatch from »le 

 Baical meridional» but so far south as in Mongolia it does 

 not appear to be known as a breeder. 



Panis atricapillus baicalensis (Swinhoe).

Wing in the former 64mm in the latter of the same 

 length, although worn. These measurements are rather 

 smaller than those generally recorded which may be due 

 to the sex of the specimens. 



It appears as if this and several of the following species 

 had not been recorded as breeding birds in MongoHa before.

All adult specimens in this collection are in a bad state 

 so thafc a close. comparison with others is difficult but they 

 appear to agree with typical specimens. 



Laiiius cristatus cristatus (Linnaeus).

The former of these specimens is a httle paler below 

 and shows some dark vermiculations which are entirely 

 absent in the latter specimen which also is more strongly 

 buffcoloured beneath. Length of wing 84 mm. 



According to Hartert this species breeds in Northern 

 Siberia »bis zum Baical-See» (1. c. p. 446). Its southern 

 limit is thus somewhat extended by this collection.
