Description. — Type, No. 7141 U.S. Nat. Mus.; Shoalwater Bay, Wash- 
ington, Oct. 31, 1854; 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 webs 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 pa/udicola appears to be 
relatively as well as actually shorter, being not decidedly longer
