MACGILLIVRAY'S WARBLER. 77 



much compressed, covered before with seven scutella, behind with two 

 longitudinal plates meeting so as to form a thin edge ; the lateral toes 

 nearly equal, the third much longer, and imited at the base to the 

 fourth, hind toe stronger and rather large ; claws moderately arched, 

 extremely compressed, laterally grooved, acute. 



Plumage soft and blended, with little gloss; wings rather short, 

 somewhat concave ; the second, third, and foiu-th primaries having the 

 outer web cut out toward the end ; the second quill is longest, the third 

 a quarter of a twelfth of an inch shorter, the fourth half a twelfth 

 shorter than the third, and one-twelfth longer than the first ; the other 

 primaries very slowly graduated, the longest or second being only five 

 and a half twelfths longer than the first secondary. All the quills, 

 primary as well as secondary, are rounded ; and there are only nine 

 primaries. Tail rather long, rather narrow, slightly divaricate and 

 considerably rounded, the lateral feathers a quarter of an inch shorter 

 than the middle, which are longest ; all the feathers rather narrow, but 

 scarcely pointed. 



Upper mandible brownish-black, its edges in their whole length 

 pale yellowish flesh-colour, as is the lower mandible, which, however, 

 is a little dusky at the end. Iris hazel. Feet and claws flesh coloured. 

 The upper part of the head, the hind part and sides of the neck, are 

 deep ash-grey, tinged with blue ; the back, scapulars, and rump light 

 olive -green ; the wings and tail greyish-brown, the edge of the wing 

 and the outer margin of the first quill bright yellow, the other primaries 

 narrowly edged with greenish-yellow, the secondaries of a paler brown 

 externally, as are the tail-feathers. From the ridge of the upper man- 

 dible to the eye is a broad band of velvet-black, which extends a little 

 way under the eye ; on each eyelid is a distinct patch of pure white, 

 but that colour does not surround the eye, the marginal feathers of the 

 eyelids being black before and behind. The fore part of the neck and 

 a portion of the breast, to the distance of an inch and five-twelfths from 

 the bill, are greyish-black, with lunulate greyish-white markings, each 

 feather being margined with that colour ; the breast, abdomen, lower 

 tail-coverts, and lower wing-coverts, are bright yellow, the sides of the 

 body yellowish-green.
