male and female have the same coloured plumage, so that one description will 

 serve for both. They differ a little in size, but their external appearance is the 

 same. They are both larger than the Pettychaps described by Willoughby ; 

 smaller than the White-throat, and nearly of the same size with the Willow- 

 wren ; but to be more particular. 



The cock-bird weighed, when just killed, exactly 7 dwts. 9 grs. ; the hen 6 

 dwts. 9 grs. The male measured, from tip to tip of the extended wings. 74- inches; 

 the female 6f. 



From the end of the bill to the extremity of the tail, the cock measured 5^ 

 inches; the hen only 5 inches. The bill in both measured half an inch, which is 

 longer in proportion than in most of this genus. The upper mandible is of a 

 dark horn colour, slightly incurved near the extremity, with a minute indenture 

 on either side near the point ; the lower is pale red or flesh-coloured, with a shade 

 of yellow ; the inside of the mouth deep orange-coloured ; the tip of the tongue 

 cloven and ciliated ; the nostrils oval, and destitute of a bristly covering ; but at 

 the base of the upper mandible, on either side, near the angle of the mouth, arise 

 3 short vibrissas pointing downwards, black at their summits, white at their bases; 

 a circumstance common to many others of this genus. The iris of the eye is 

 olive-brown ; the pupil black. The short feathers of the orbits or eye-lashes are 

 of a dirty white colour. From the corner of each eye to the nostril is a broad 

 stroke or band of tawny-white feathers, lying over each other, and running nar- 

 rowest towards the bill ; this affords an excellent mark to distinguish the 

 species. 



The feathers of the head, neck, back, coverts of the wings and rump, are of an 

 olive-brown, with a slight tinge of green. The quill and tail feathers are all of a 

 darker hue, or simply brown ; their outward edges of a paler shade. The tail is 

 1 inches long, slightly cuneated, the middle feathers being a little longer than the 

 rest, the others gradually shorter ; all of one uniform dun-brown colour edged 

 with paler brown, and a little wedge-shaped at their ends. The chin is white; 

 the throat, breast, belly, and parts about the vent, are white with a slight shade 

 of buff or tawny ; but all these feathers (as in several others of this genus) when 

 blown asunder, or closely examined, are found to have their base or lower half 

 black, except the shafts, which are white throughout. The ridge and under 

 coverts of the exterior angle of the wing are of a yellowish-tawny colour, as are 

 also the feathers of the thighs ; but those of the knees are a shade darker, or a 

 pale yellowish brown. The legs are a light olive ; the soles of the feet bright 

 yellow, with a tinge of green, which soon fades after the bird is dead. The in- 

 step is covered with 7 large imbricated scales, and 5 smaller on the toes, as in 

 others of the genus. The toes stand 3 before, and 1 behind : the claws are 

 nearly of equal length and curvature; but the hindmost is thickest and strongest.
