188 THE GOLIEVSKI ISLANDS 



Gplovinski, and Bogdanoff; published at Kasan in 1871. 

 From this book Cocksure drew for us the following 

 information : 



"Little and Temmincks stints are seen in flocks 

 during the first fortnight in May on the Volga, from 

 Simbirsk to Kasan, and on the Kama as far as Uffa. 

 They are not seen during the summer, but are found 

 again at Simbirsk in the middle of August. 



" Curlew sandpipers are seen in Kasan in spring and 

 autumn only, both on the Volga and Kama. 



" Sander lings are seen in autumn at Kasan, and have 

 been seen in spring on the Sarpa. 



" Grey plovers are seen in small flocks in May and 

 vSeptember near Kasan, but are not to be met with every 

 year. 



" Yellow-headed wagtails arrive at Kasan with the 

 common species, viz., middle of April ; a few pairs are 

 seen until the beginning of June." 



These extracts prove that part of the migration of 

 these species takes place across country ; but probably 

 the main stream follows the coast, especially in autumn, 

 as I was myself an eye-witness, the year after my return 

 from the Petchora, on the island of Heligoland.
