ORNITHOLOGICAL EXPLORATIONS. 



349 



ing nearly a year. Finally the Eussian Transit-of- Venus Expedition 

 brought home a few species of birds from Tschukotskij Noss. 



Scanty as this material is, both on account of the limited extent of 

 the explorations and the northern situation of the country (64 to 67^ 

 north latitude), it is better than nothing, and will suffice for some in- 

 teresting observations. It will be necessary first to give a list of the 

 summer visitors of that region, which are of importance in the present 

 connection. We have, consequently, left out all the strictly American 

 forms which in summer visit the Tschuktschi Peninsula. 



Table XV. — Palcearctic Summer Visitors {Land Birds and Fluviatile 

 Waders) known to occur on the Tschuktschi Peninsula, 



Arenaria interpres. 

 Charadrius squatarola. 



dominicus fulvus. 

 iEgialitis hiaticula (?) 

 Eurynorhynchus pygmseus. 

 Eudromiaa moriuellus. 

 Actodromas acuminatas. 



temrainckii. 

 Pelidna ferruginea. * 

 Calcarius lapponicua. 



Anthus gustavi. 



japonicus (f) 



cervinua. 

 Budytes flavua lencostriatas. 

 Motacilla ocularis. 

 Phyllopseustes borealis. 

 Tardus iliacus (f ) 



naumanni (?) 

 Saxicola oenanthe. 



In spite of the meagerness of this list, it confronts us at once with 

 the very important fact that it contains a number of species which, 

 have not yet been obtained in Kamtschatka, and most of which, prob- 

 ably, do not occur there regularly, viz : 



^gialitis hiaticula (?) 

 Eudromias morinellus. 

 Pelidna ferruginea. 

 Eurynorhynchus pygmseus. 



Motacilla ocularis. 



Turdus iliacus (?) 



naumanni. 



Saxicola oenanthe. 



In this connection I wish to recall what I have said previously in 

 this work (p. 283 and p. 303) in regard to Budytes leucostriatus and 

 Phyllopseustes borealis, viz, that there seems to be a slight difference 

 between the stock inhabiting Alaska (and the opposite shore of Asia) 

 and the one which passes the summer in Kamtschatka, indicating that 

 the former never touches the latter country during their migrations.

 seen from the following list of the chief synonyms :
