FINSCH ON THE BIRDS OF TRINIDAD. 563 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. n. 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 underparts and the extent of the light shaft-spots is also variable, and will not allow of a specific separation. The Bogota one has the underparts 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.
