Of this bird wbicli was ratlier uunierous in the vicinity of Petropaul- 

 ski, I liave already given an account in my '' Contributions," «&c., Pr. 

 U. S. Kat. Mus., 1883, p. 92, which need not be rejjeated here. 



On the 21st of June I obtained a female on Bering Island. It was 

 shot among the high grass near the beach, between Severnaja Seal- 

 rookery and Saranna, and was in company with two others of its kind. 

 Two others were shot and prepared on Bering Island, when I was ab- 

 sent on a trip to Copper Island. They were both said to be males. It 

 is only an occasional visitor to the island.

Seebohm (Brit. Mus. Cat., V, p. 119) describes the under wing-cov- 

 erts and the axillaries as " pale chestnut." In my bird there is not a 

 trace of such a color; in fact these feathers are of a pale bufifish white. 

 They agree much better with Cassin's description, where they are 

 stated to have '• a tinge of a very pale reddish." I have examined Cas-
