Lake region, though tinged with yellow on the chin, are, on 

 account of size and colors somewhat paler than alfiestris, refei'able 

 to leucolcema ; so too are large dark birds with white eyebrows 

 and pale yellow chins found in winter in the upper Mississippi 

 Valley, coming as they doubtless do from an intermediate region 

 between Hudson's Bay and Alaska. Breeding birds of these two 

 races are few and limited mainly to those taken on Government 

 expeditions ; consequently I do not draw the lines on the map as 

 closely together as with some of the other races better defined. 



Two young in first plumage taken on the Arctic Coast east of 

 the Anderson River may be referred to this race. While they 

 are not as black and white as might be expected in Alaskan birds, 

 they lack the general yellowishness of young alpestrls from New- 

 foundland. In winter leucolcema is found as far south as the 

 middle of the western United States, mostly east of the Sierra 

 Nevada Mountains. Northwest coast specimens indicate that a 

 small-sized leucolcema may breed in the mountains not far north 

 of the United States boundary, though such birds may generally 

 be referred to merrilli. A male in autumn plumage taken Aug. 

 26, at Chief Mt. Lake on our northern boundary, Long. 1 14 W., 

 suggests the possibility of this form breeding also on the moun- 

 tains at that point or not far to the north of it. It is not reported 

 from Pt. Barrow, is rare at St. Michaels, Alaska, and is probably 

 an interior race. A winter example from Long Island, N. Y., 

 shows how far it may stray at that season, though this bird is 

 hardly typical. 



Average measurements of 9 breeding males: wing. 111.8 mm. (4.40 

 in.) ; tail, 74.7 mm. (2.94 in.) ; tarsus, 22.4 mm. (.88 in.) ; bill from nostril, 

 9.9 mm. (.39 in.).
