These two specimens are showing the following measure- 

 ments: 



Wing = 101—94 mm. 

 Tail == 57—62 » 

 Bill = 14—14,5 » 

 Tarsr.s = 15,5 — 15 » 



Both the females are without the ash-gray feathers which 

 are characteristic for the proximal Petronia petronia exiguus 

 Hellm. The Rock-sparrows found in Turkestan are the 

 greatest known sparrows. As is seen by the measurements 

 given above the specimen shot on the lOth of March has a 

 considerable greater size of the wings than the other one 

 and perhaps it is a male although laballed a female.

There is no doubt that these yellowhammers belong to 

 the subspecies discribed by Brehm as Emberiza citrinella ery- 

 throgenys. I have compared the Tian Shan birds with seve- 

 ral birds from Sweden and I have found that both the male 

 and the females are paler than the swedish specimens. But 

 there is little but no difference in wing measurements 

 between the typical Emberiza citrinella L. and Emberiza citri- 

 nella erythrogenys. For comparison I give some wing mea- 

 surements made on swedish birds.
