eies, however, may be known by the shortness of the hind claw, 

 which is never longer than the toe, by their black ear-coverts, the 

 darker shade of the back, and especially of the crown, the light- 

 brown stripe above the eye, which does not extend in front of it, 

 as in (7. Japponica, and by the greater curvature of the culmen. 



The young males, when able to fly, but with the wings and 

 tail not fully developed (about 4 weeks old), have the crown of 

 the head almost black, most of the feathers here and there with 

 brown radii; the white band, which, in the old birds, stretenes back 

 behind the ear and down above the ear-coverts, begins in the young 

 ones on the forehead, the black crown being thus ,circled in infront 

 with white. Ear-coverts black, throat whity-grey, but the fore-neck 

 marked with a blotch of black, which subsequently spreads over 

 the breast. The broad band on the nape browny-red, sides of the 

 breast whitish, vent yellowy-white with a rusty tinge, bill yellow, 

 tipped with black, feet browny-black. 



The young females, of the same size as the males, have the 

 crown of the head brown with black shafts, the band on the nape 

 indistinct and dotted, ear-coverts as in the males; throat whity- 

 grey, the latter marked like the breast with darkish spots; vent, 

 bill, and feet as in the males. 



For the rest, the dark-brown colour of the feet in C. lappo- 

 nica pales considerably in stuffed specimens. Such is also the 

 case, in a striking degree, with the colour of the vent and of the 

 feathers of the wings, both in old and young birds, the belly, in 

 individuals just shot, being yellowish with a tinge of red, but this 

 colour gradually fades into white. 



There was often considerable disparity in the plumage of the 

 females; in some, the dark blotch on the breast approached a 

 whity-grey, sparsely sprinkled with black feathers. The total length 

 of a male was 166V 2 mm ; wing 94, tail 65; total of a female, 

 156 mm; wing 84 %, tail 58. Only insects and fine gravel were 

 found in the stomachs. 



In 1872, the colony near Fokstuen, on the Dovre (vide Nyt Mag. 

 f. Naturv. Vol. 18 p. 172), was found habiting the locality it had
