ART. 12 BIEDS OF ST. LAWRENCE ISLAND FEIEDMANN 13 



determine the subspecific identity of such a specimen satisfactoril}'', 

 but Phillips considers St. Lawrence Island as within the breeding 

 range of the American race tzltzihoa, with which I hnve identified 

 Collins's bird. It has the broad speculum supposed to be charac- 

 teristic of tzitziJwa.

Nelson saw old-squaws about St. Lawrence Island during his visit 

 there in June and July, 1881. Brooks found them very common, in 

 pairs and small flocks, on June 2. He notes that when " paired, the 

 female very often flies ahead of the male, as does the female eider. 

 A set of six fresh eggs was taken at St. Lawrence Island, June 25, 

 1913." Bailey obtained a set of five eggs there on July 9. While on 

 the island with the other naturalists of the Harriman Expedition 

 on July 13, 1899, Dr. A. K. Fisher obtained a specimen of this duck. 



Collins obtained a male at Gambell in August and a female there 

 on October 17. Both birds are in a molting condition.
