Adult Male: Bill variable, often just as in A. boschas boschas but sometimes shorter, and occa- 
sionally narrower. The upper surface of the body in general less brown and more gray in color and 
the upper wing-coverts more brown and less gray. The wavy markings On the flanks are coarser, 
more gray and white; while the reddish brown breast area shows a tendency to end in a point, 
which is often well defined. The tips of the breast feathers are nearly always marked with black 
spots or cross-bands. The rest of the lower side is somewhat grayer and darker. Wing of eleven 
specimens, 280-303 mm. 
Female: Upper side grayer than in A. b. boschas, edges of the feathers and the barring light gray- 
brown instead of reddish brown. Lower side strongly spotted, even in old birds, and similar to the 
young oi A. b. boschas. Only very rarely are the under parts so uniform and washed out as in old 
European specimens. Furthermore they are whiter and not so rusty (Hartert, 1920). 
Range: Greenland, on the west coast north to Upernavik and on the east coast north at least to 
Angmagsahk.
