 1, 1882. Collected by Charles L. McKay. Original number 96. 



No type specimen was designated at the original description, but specimens 

 were examined from "Alaska, Pacific coast, Guatemala, Arctic and Atlantic 

 coasts, and interior of the United States." Oberholser, during preparation 

 of his "Birds of Louisiana," brought together so far as possible Stejneger's 

 old material and asked the latter to set aside a lectotype. No. 89226, ap- 

 parently the only one of the original series from Bristol Bay, was thus chosen 

 and bears on its label, in Stejneger's hand, the words "nearctica Stejneger" 

 and also "Type, L.S."
