254 Hanna, New Birds for the Pribitofs. [April 



recent years but in every case they were flying high and of course could 

 not be sufficiently well identified to make a specific record of value. This 

 specimen is the first positive evidence that the species occurs. It is en- 

 tirely probable that several other large hawks may eventually be secured. 



Petrochelidon lunifrons lunifrons (Say). Cliff Swallow. — A 

 Cliff Swallow was shot and skinned on St. Paul Island about June 10, 1918, 

 by a native from whom the specimen was secured. This makes the second 

 species of swallow to be collected on the Islands; the Northern Violet- 

 green was taken in 1914. The barn swallow has also been recorded but 

 not collected. 



Plectrophenax hyperboreus Ridgway. McKay's Snow Bunting. — 

 Since this species is known to wander from its only breeding place, St. 

 Matthew Island group, to the mainland of Alaska, it has been expected 

 and searched for on the Pribilofs for several years. But it was not definite- 

 ly known to come until March 30, 1918, when a male in full winter plu- 

 mage was secured on St. Paul Island. It and a female, which escaped, 

 were found on the top of Rush Hill, the highest point of the Island. 



Junco hyemalis hyemalis (Linnaeus). Slate-colored Junco. — 

 Two female juncos were secured from a flock of six at North East Point, 

 St. Paul Island, on September 24, 1917. They were feeding about the 

 buildings there, apparently as contented as if they were in the midst of 

 civilization. 



Spinus pinus pinus (Wilson). Pine Siskin — A male Pine Siskin was 

 secured from a flock of twelve found among the North East Point sand 

 dunes, St. Paul Island, on September 24, 1917. The birds seemed to be 

 perfectly satisfied to feed on the seeds of the few ground plants which 

 grow there. 



Hylocichla aliciae aliciae (Baird). Gray-cheeked Thrush. — A 

 female Gray-cheeked Thrush was collected on St. Paul Island, September 

 9, 1917. It was found feeding on spaded up ground about the Naval 

 Radio Station.
