Hab. — Seems to be less northerly in its distribution than 

 B. brevirostris, and perhaps B. perdix, its chief breeding ränge being 

 apparently from the eastern Aleutian Islands and the Mainland coast 

 of Alaska south ol 60 ° N. Lat. to Puget Sound, migrating south, in 

 winter, as far as San Diego. Its alleged occurrence in Asiatic waters 

 may be regarded as quite doubtful. 



The distinguishing characters of this species, as compared 

 with B. brevirostris and B. perdix, have already been treated of in 

 connection with these species. Numerous specimens in transition 

 plumage from B. wrangelü to B. marmoratus, and vice versa, prove 

 beyond a shadow of doubt, thatthe former is only the Marbled Mur- 

 relet in winter plumage.
