54 PROCEEDINGS OF THE NATIONAL \llsi:r\l. vol.38. 



Judging from my material this appears t<> be a more richly colored, 

 darker, more finely marked form than L. I. alius, the markings above 

 liner, with much less rufous, and the lower part of the prsepectus 

 finely vermiculated, instead of clouded with black. 



The single specimen in my collection was obtained by Mr. F. M. 

 Chamberlain on July 13, 1905, on Twin Rift Peak above McDonald 

 Lake in southeastern Alaska, al an elevation of about 3,000 feet. 

 It is a male bird, and was followed by a brood of young at the time 

 of capture, although the ground was still covered with patches of 

 snow . 



This bird differs in some respects from the series of L. I. alexandrse 

 from other parts of Alaska; the culmen is strongly curved toward 

 the tip instead of regularly curved for its entire length, and the 

 genera] coloration is darker and more rufous, the feathers above 

 lipped with hull' instead of white. It measures: Wing 190 nun.; tail 

 117 nun.; tarsus39mm.; middle toe 27 mm. ; culmen 19 mm.; depth 

 of hill 1 I nun.: distance from inferior corner of maxilla, to tip of cul- 

 men 23 nun.; width of hill at base 12 mm. It is possible that it 

 may represent a new race peculiar to the mountains of southeastern 

 Alaska, hut a large series will he necessary definitely to determine 

 this point.

 WILLOW PTARMIGAN. 



Some form of Willow Ptarmigan was found to he not uncommon 

 in the lowlands behind Petropaulski, Kamchatka, hut the birds 

 were verj shy and I did not succeed in getting any specimens.
