350 ORNITHOLOGICAL EXPLORATIONS. 



We know for certain that none of the above species migrate southward 

 along the American coast, not even those which regularly visit Alaska 

 in summer. They must, therefore, migrate south through some part of 

 i^ortheastern Asia, since they do not stay near Bering Strait in winter. 

 That all of them should have been overlooked in Kamtschatka is not 

 probable. It may, at least, be taken for granted that they do not 

 regularly pass up and down the eastern coast twice a year. 



It is, in this connection, a significant fact that these same birds do 

 not regularly occur in Japan either, with the possible exception of two, 

 viz, the birds which in Table XV are called ^Jgialitis hiaticula and 

 Turdus naumanni. The former is not found in Japan ; on the other 

 hand, the nearly allied jEgialitis placida is common in winter about 

 Yokohama, and the bird which Nordenskiold brought home from the 

 winter quarters of the " Vega" may have been this species and not the 

 true hiaticula. The true Turdus naumanni Temm. is included in the 

 Japanese fauna, but Blakiston and Pryer say that it " does not seem to 

 be abundant." It is to be remarked that Middendorff met this species 

 on the western shore of the Okotsk Sea, at Ajan, and in the Stanovoj 

 Mountains (54^° and 59^° north latitude), but that he erroneously calls 

 it Turdus rujicollis. 



In regard to Eurynorhynchus pygmceus it must be observed that, al- 

 though several specimens have been obtained in Japan, it is not known 

 to occur there regularly. Still the fact that this bird, in spite of its 

 most extraordinary bill, has escaped notice in other places until recently, 

 makes it less safe to base any conclusions upon the negative evidence 

 of its not having been recorded from a given locality. This species 

 needs close watching everywhere in Eastern Asia, for not only is it a 

 rare and curious bird, but it is confidently expected that considerable 

 light will be thrown upon the migrations of that region when the route 

 of the Spoonbilled Sandpiper shall have been mapped out. 



The migratory inhabitants of the Tschuktschi Peninsula, which in 

 fall go south to winter in some part of Eastern or Southern Asia, are 

 most likely to follow the southern coast of the peninsula westward, or 

 to cross the Bay of Anadir, in both cases reaching the great river sys- 

 tem of Anadir. A glance at the map w ill convince us that they do not 

 cross the range of the Stanovoj Mountains, which here separate the 

 Anadir system from that of the Kolima. The direction of this mount- 

 ain range is southwest, and parallel with it is another mountain sys-
