24 ART. 13. — E. LÖNXBERG : 



26. Poliomyias initgimaki (Temminck), 



Mouth of Susiiya River: Icf^, May 16; Id", May 18. 

 Tretiya Paclj : 3(/'c/', May 30; 2c/ c/', June 1; Id", June 



3; 1 specimen (unsexed but no doubt a$), Icj^, 



June 8. 



Of these specimens only 4 are males in full plumage with 

 black upper parts, a white mark behind aya and a white wing- 

 patch. In some of the others, however, the mark behind the eye 

 is only more or less indicated by a dirty whitish spot and all 

 these specimens have white base to tail-feathers, indicating their 

 sex. As they were all shot in Spring and in early Summer, it 

 may be taken for proved that the bird does not assume its full 

 plumage before it is more than one year old. 



This little flycatcher was not mentioned by Nikolski among 

 the birds found by him in Saghalin, but as its distribution 

 ranges from Baikal to the mouth of Amur, it is no wonder that 

 it crosses over to Saghalin. It evidently breeds there. 



Prof. I.TiMA writes me about the bird thus : " On May 30th, 

 after rain and northerly gale had lasted for the previous two 

 days, the coast near Korsakoff was quite alive on account of 

 tlie sudden appearance of this bird in very large numbers. The 

 birds seemed not to heed the approach of man to within a few 

 feet. On the following day they were found to have greatly 

 decreased in number ; still not a few seemed to have remained, 

 apparently to breed, on the verge of the woods."
