63 Th. von Heuglin on the Birds of 



unable to fly. The autumnal moult of the old ones takes place 

 at the end of August. The southward migration begins in the 

 middle of September ; and then the Snow-Buntings are generally 

 in closely packed flocks. 



t7. Lagopus, sp. ? — Sporer^ N. Semla, p. 98. 



According to Pachtussow there are Ptarmigans on the Double 

 Island. I believe I found in Matthew^s Strait the remains of a 

 species of Lagopus ; and a Norwegian of our company, who knew 

 these birds well, asserted that he had seen a " Ripa " in Dolphin 

 Bay. It would, indeed, be remarkable if this genus wei'e not 

 here represented, although there are an extraordinary number of 

 Arctic Foxes, which in the winter must be very destructive to 

 these animals. 



8. Charadrius apricarius. — Von Middend. /. c. p. 210. 

 Very common on the continent near Yugorsky Strait ; more 



rare on Waigats. 



9. Eudromias morinellus. — Gillett, no. 6. 



Observed by Mr. Gillett in Matthew's Strait. We found 

 small flocks near Yugorsky Strait. At the beginning of Sep- 

 tember the young had still some down on the back of their 

 head ; the adults change even the small feathers. 



10. ^GiALiTis hiaticula. — Gillett, no. 7. 



Everywhere common ; they must breed late, as we found 

 nestlings in the middle of August. 



fll. Strepsilas collaris. — Sporer, N. Semla, p. 98. 



Occurs, according to Von Baer,on Novaja Semlia — information 

 which gains probability, as Von Middendorff met with the Turn- 

 stone, on the Taimyr, as far as lat. 74° N. 



12. Tringa maritima. — Gillett, no. 8. 



Everywhere common, and generally in pairs. In autumn in 

 smaller or larger flocks, and often mixed with T. cinclus and T. 

 mimita. On the 8th of August I found nestlings still very small, 

 and covered with down. 



13. Tringa cinclus. 



Very common in September on Waigats.
