. Al., 46.5-53 (50.1) mm.; caud., 40.5-48 (43. S) mm.; culm, exp., 11. 5-12 

 (11.9) mm.; tars., 17-20 (18.2) mm. 



Habitat. — Pacific Coast from \V\'tsliington to California, south in 

 winter to extreme northwestern Mexico. 



Description. — Type, No. 7 141 U. S. Nat. Mus. ; Shoalwater Bay, Wash- 

 ington, Oct. 31, 1S54; Dr. J. G. Cooper. Pileum and nucha brown, inter- 

 mediate between mummy brown and bistre; upper parts generally of 

 similar color, but paler and grayer on scapulars, more reddish on rump 

 and upper tail-coverts, the latter heavily barred with black; lateral stripes 

 on pileum, and large triangular patch on lower cervix and interscapulum, 

 dark clove brown, this patch broadest anteriorly, where reaching to sides 

 of neck, the feathers with conspicuous white shaft streaks. Tail like the 

 rump, becoming hair brown on terminal portions of outer feathers, heavily 

 barred with black, these markings more or less confluent on all but the 

 central pair, the basal portions of inner Avebs of some of the feathers 

 being almost solidly black. Wings dark olive brown ; edgings of coverts 

 and indentations on quills brown, nearly like the scapulars ; entire 

 outer webs of tertials and spots on external webs of greater coverts black. 

 Sides of head and neck, with auriculars, light mummy brown mixed 

 with grayish ; superciliary stripe, and lower parts generally, dull white 

 with a slight buffy wash, heavily shaded with dull buffy across breast ; 

 sides and flanks dull cinnamon; crissum strongly barred with mummy 

 brown, and on longest feathers with black. 



The much darker colors both above and below, with the greater 

 extent of the dark portions of the pileum, readily distinguish this 

 coast form from C. p. plesius. The bill of /(?/«rt''/r<7/a appears to be 

 relatively as well as actually shorter, being not decidedly longer
