is black only at the base of the outer web (not wholly), and that the 
fifth on the left side only is varied with black, whereas the fifth on 
the right hand is uniform rufous like the two innermost. In a 
specimen from Bogota, received from J. Verreaux (s. un. littoralis, 
Scl.!), the outermost is quite rufous, the second black at the base of 
the inner web, the third black on the inner web (except a rufous 
apical spot), the fourth wholly black on the inner web, the fifth 
black on the outer web. A specimen from Brazil (Canto Gallo) has 
the two outer feathers wholly rufous, the third and fourth black on 
the inner web, the fifth rufous with black interrupted shaft-stripe. 
It is easy to perceive that these differences in the colouring of the 
tail-feathers are of no specific value. The colouring of the under- 
parts and the extent of the light shaft-spots is also variable, and will 
not allow of a specific separation. The Bogota one has the under- 
parts more greyish olive-brown with narrow whitish streaks, precisely 
the same as in a Brazilian specimen; the other Brazilian one has 
much broader shaft-streaks; in the Trinidad bird they are not so 
broad, but the colour of the underparts is more rufescent olive.
