of Oregon, in October. No specimens being in the collection, it may 

 be observed, however, that the smaller species [FuUgula mariloides), 

 nearly allied to this bird, has also been found on the western coast of 

 North America, and is given in the Zoology of the Voyage of the Blos- 

 som, Ornithology, p. 31. 



Dr. Townsend gives FuUgula marila, as a bird of Oregon.

On minute comparison between specimens from the Pacific, in the 

 present collection, with others from the Atlantic coast, we find no dis- 

 tinctive characters. 



Mr. Peale observes of this bird : 



" Common on the west coast of North America, with Oidemia fusca, 

 and extends its migrations further south. Never found but in the 

 immediate vicinity of the sea, and as its name implies, generally in 

 the surf." 



Dr. Pickering also records the occurrence of this species in Oregon.
