303

 of mouth cbrome yellow. Feet dark grayish browu, toes below yellow.

 brownish gray, tarsus behind and toes below yellow. 



The above specimens have been carefully compared with a series 

 from Alaska and iinother from China. But as both are too imperfectly 

 labeled by the collectors, nothing- definite can be sai<l. Both series 

 show ini'erior dimensions, which may be ascribed to the occurrence of 

 females, while the Kamtschatkan series unfortunately only includes 

 maks. But it would seem as if the Alaskan birds have a comparatively 

 smaller bill and smaller size altogether, and I should not be surprised if 

 a larger and better determined series of specimens from Alaska would 

 prove them entitled to rank as a subspecies under the name of Ph. horealis 

 Jcennicotti (Baird). The case is absolutely parallel to that of Biidytes 

 flavun leKcostriatus, offering the same suggestions as to the migratory 

 route of the Alaskan birds.
