in steliaris), and the rump and tail coverts are plain, or with very 
obsolete markings. 
The characters derived from my present materials are as follows, 
and will probably be substantiated by additional specimens :— 
C. steliaris.x—White dorsal streaks extending to the rump, which is con- 
spicuously banded with brown, and somewhat spotted with whitish. 
Beneath, including lining of wings, light cinnamon-brown; throat and 
belly paler, almost white; sides and ¢crissum very obsoletely barred 
with darker, and faintly spotted with whitish. Feathers of jugulum like 
sides, but with the color obscured by the paler edges. Tarsus, .65 long. 
©. elegans.—Streaks on back confined to interscapular region; rump and 
upper tail coverts almost plain reddish-brown. Beneath much paler than 
in stellaris, without any appreciable indication of bars or spots on sides 
and crissum, or of the fulvous of the jugular feathers. Inside of wings 
snowy white. Tarsus, .72 long.
