Descrijjf ion. —Type, adult male. No. 88377, U.S.N.M.; Fort 

 Walla Walla, Washington, November 13, 1881; Capt. Charles Ben- 

 dire. Upper surface brownish black, much mottled and vermicu- 

 lated with whitish, buffy, and ochraceous, the last most conspicuous 

 anteriorly, but the subbasal portions of all the feathers more or less 

 ochraceous; wing-coverts like the back; wing-quills fuscous, barred 

 broadly though somewhat irregularly on outer webs with dull buffy 

 or brownish white, on interior webs with ochraceous; tail sepia, 

 barred lirokenh^ and vermiculated with whitish, buff, and ochraceous, 

 the last predominating; forehead and siipraloral line grayish white, 

 mixed with ochraceous and brownish; facial disk ochraceous, some- 

 what mixed with blackish, and bounded behind by a black l)and; horns 

 blackish, with considerable ochraceous on inner webs and basal por- 

 tions; sides of neck mixed dark brown, whitish, and ochraceous; chin 

 and throat white, divided by a collarette of dark brown, ochraceous- 

 margined feathers; remainder of lower surface white and ochraceous, 

 heavil}^, and in places confluenth^, barred with brownish black, the 

 breast also blotched with the same; lining of wing white and ochra- 

 ceous, barred and spotted with blackish; legs and feet ochraceous, 

 barred and spotted with dark brown. 



This subspecies differs tron\j?acificus in its larger size; darker upper 

 and lower parts, the latter more heavily barred; more strongly mot- 

 tled legs and feet; darker and more rufescent facial disk. It is appar- 

 ently most closely allied to saturatus and icelus, but is quite easily 

 distinguishable from either. 



The specimen from Pengra, Oregon, here referred, is decidedlv inter- 

 mediate between lagophonus and occidental is. Birds from Cook Inlet 

 and the interior of Alaska are in color apparently identical with those 

 from Idaho and Washington, though one from Fort Yukon is almost 

 dark enough for saturatus. These birds from Alaska are, however, 

 somewhat larger than typical lagophonus., and their inclusion in the 

 measurements above given to some extent accounts for the wide range 

 of variation. 



Although there is much individual color difference among examples 

 of this race, yet, in so far as is shown by our material, there is little 

 or no indication of a pale phase. 

 . Specimens from the following localities have been examined: 



Washington. — Walla Walla; Cascade Mountains; 25 miles southeast 

 of Toledo!
