BIRDS OF NORTH AND MIDDLE AMERICA. 223 
- basal phalanx of middle toe united for more than half its length to 
lateral toes; claws moderate to rather large, strongly curved, that of 
hallux decidedly shorter than the digit. 
Coloration.—Above brown, usually darker and duller (sometimes 
more grayish) on pileum and hindneck, the tail and upper tail-coverts 
chestnut or chestnut-brown; under parts brown or olive, more or less 
distinctly streaked with tawny, ochraceous, or buffy—the pileum and 
hindneck, or even the back, sometimes similarly streaked. Sexes 
alike. 
Nidification— Unknown? 
Range.—Costa Rica to Ecuadér (to Peru, Bolivia, and southeastern 
Brazil?*). (Several species.) 
RHOPOCTITES RUFOBRUNNEUS (Lawrence). 
STREAKED AUTOMOLUS. 
Adults (sezes alike)—Pileum and hindneck dark grayish brown or 
brownish gray, the feathers margined with blackish; back, scapulars, 
and wings deep warm-sepia or mummy brown, passing into chestnut 
on lower rump, upper tail-coverts, and tail, the shafts of rectrices 
much darker; lores mixed dusky and grayish; suborbital and auricular 
regions streaked with dusky and dull ochraceous or light brownish; 
malar region, sides of neck (anteriorly), chin, and throat ochraceous 
(more or less deep), the feathers more or less distinctly edged or 
narrowly margined with dusky olive or blackish; rest of under parts 
light tawny-olive, more olive on chest, where more or less broadly 
streaked with ochraceous, usually more ochraceous on abdomen, the 
under tail-coverts more rufescent; under wing-coverts tawny-ochra- 
ceous, the inner webs of remiges broadly edged with pale ochraceous- 
buff or deep pinkish buff; bill black, the mandible usually brownish 
basally; legs and feet horn color (in dried skins). 
@The above diagnosis and description are based exclusively on Philydor rufo- 
brunneus Lawrence and Automolus ignobilis Sclater and Salvin, but several other 
species referred to Automolus by Sclater and others seem to be nearly related and 
perhaps are—some of them at least—congeneric. These are: Automolus ferrugino- 
lentus (Maximilian), A. holostictus Sclater and Salvin, A. striaticeps Taczanowski, A. 
subulatus (Spix) and <A. stictoptilus (Cabanis), none of which have been examined 
by me. 
Rhopoctites ignobilis differs considerably from R. rufo-brunneus (type of the genus) 
in shorter, deeper, and relatively more compressed bill, and, apparently, in relatively 
shorter tail; but the differences are within the usual normal limits of variation.
