The food of this bird is the usual variety of seeds, 

 insects, leaves, berries, and buds of different plants and 

 trees, and one individual had his crop fdled with sphag- 

 miin moss. They go in small coveys, and but one brood 

 is raised in a season: each covey being composed, proba- 

 bly, of members of the same brood. The eggs, deposited 

 in June in a nest similar to that of the Rock I'tarmigan, 

 are absolutely indistinguishable from those of that 

 species.

Geoj^rap/ii'cal Distribution. — Northern Labrador, and islands 

 on the west shore of Cumberland Gulf, Greenland. 



Adult Male in Summer. — Very similar in general pattern of 

 markings, and in coloration to L. rupestris, but not so regularly 

 barred above, and the bars much coarser. 



Adult Female in Summer. — A'autilik, Cumberland Gulf. — In 

 general appearance this is a black and white bird, with the 

 black predominating; top of head, back, rump, and upper tail- 

 coverts, black, with from one to three buffy white spots on the 

 outer edge of the webs, and each feather more or less distinctly 

 tipped with white; a few feathers, mottled with pale buff and 

 white for about one-third their length from the tip, are scattered 

 over the back, these probably belonging to the plumage charac- 

 teristic of autumn, and which will next be assumed; the throat, 

 sides of head, and neck all around are buffy white, barred nar- 

 rowly with black; scapulars, most of the secondaries, and greater 

 wing-coverts are colored like the back, but all the feathers are 

 tipped with white, giving this part a black and white appear- 

 ance, with only occasionally pale buff spots showing; feathers of 

 under parts, flanks, and under tail-coverts, barred with black and 

 light buff, and tipped with white, but the black predominates; 

 the flank feathers have much broader bars of both black and pale 

 buff, and the latter is more conspicuous here than on any other 

 part of the bird; tail, seal brown, edged with white at the tips;
