Calandrella brachydactyla (Leisler). 

 Has occurred several timeSj both in tlie spring (May and 

 early June) and in the autumn (September to November). 



Otocorys alpestris (Linnseus) . 



Twenty-five years since this species was so rare that Mr. 

 Gatke had to give four shillings for a specimen ; now it is so 

 common that nobody thinks it worth shooting. It arrives in 

 the autumn with a northerly w ind^ from the middle of Oc- 

 tober to the middle of November, day after day, and often 

 in flocks of hundreds'^. 



Emberiza lapponica (Linnaeus). 



So common in the autumn that it is not considered worth 

 shooting. 



Emberiza nivalis, Linnseus. 



In large flocks in the later autumn. Mr. Gatke has in his 

 collection mature birds, both of the larger and smaller races, 

 in breeding-plumage. There is certainly in these examples 

 a remarkable difi'erence in size.
