Acanthopneuste borealis borealis (Blasius). 



Five specimens, all males, Nijni Kolymsk, June 8 to June 19, 

 1912. 



This species arrived at Nijni Kolymsk, May 30, 1912. During 

 June it was common in the forested regions. On June 13, 1912, 

 a nest was found, completed but still without eggs. On June 19, 

 when it was collected, the nest held five fresh eggs. The female 

 belonging to the nest never was seen; but the male was constantly 

 present, and, when not disturbed, sang vigorously in a tree close by. 

 He was taken with the nest and set of eggs. 



Reguloides superciliosus superciliosus (Gmelin). 



Six specimens, all males, were obtained at Nijni Kolymsk from 

 June 8 to June 17, 1912. 



This species arrived on June 8, and from then on was common in 

 the lowlands of the forested region about Nijni Kolymsk. It evi- 

 dently is a late breeder, as Mr. Koren noted that the birds were 

 only just mating at the time of his departure from the place, 

 June 21. 



In behavior it resembles a kinglet more than a willow warbler, 

 and is said by Mr. Koren to be a very restless bird. 



Laniidae. 



Lanius excubitor mollis Eversm. 



One great gray shrike was seen, on one occasion only, at Nijni 

 Kolymsk. It was wild,' and could not be secured. On geographical 

 grounds it of course must have been of this subspecies.
