This bird remained long unnoticed as a distinct species, from its
resemblance to the hay-bird (_Sylvia Trochilus_), with which it is
still frequently confounded. It measures in length five inches and a
half; bill horn-colour; upper mandible bent at the tip, and rather
longer than the under; irides hazel; nostrils beset with bristles; top
of the head, neck, back, and tail-coverts olive green; throat and cheeks
yellow, paler on the breast; belly and vent of a most beautiful silvery
white; through the eye passes a yellow line; legs rather more than an
inch long, of a horn-colour, claws paler.
