MOURNING-GROUND WARBLER. 77 



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

 thin edge; the lateral toes nearly equal, the third much longer, and united 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 of moderate length, 

 somewhat concave; the second, third, and fourth primaries having the outer 

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

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

 than the third, and a quarter of a twelfth shorter than the first; the other 

 primaries slowly graduated, the longest or second being only eight 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, considerably rounded, the lateral feathers a quarter of an inch shorter 

 than the middle, which are longest; all the feathers rather narrow and ob- 

 liquely pointed. 



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

 lowish 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 deep 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 mandible to the eye is a rather broad band of 

 black, which extends a little way under the eye, but is not nearly so conspi- 

 cuous as that of the species above described; nor are the eyelids marked with 

 white, their marginal feathers being all dusky grey. 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 deep black, with lunulate white markings, each feather 

 being margined with that colour; the white edges of the lower black feathers 

 being extremely narrow leave a crescent of nearly pure black; the breast, 

 abdomen, lower tail-coverts, and lower wing-coverts are bright yellow, the 

 sides of the body yellowish-green. 



Length to end of tail 5 inches; "extent of wings 8;" bill along the ridge 

 ■ff, along the edge of lower mandible ^f; wing from flexure 2 T 7 ^; tail 2^ 

 tarsus T j; hind toe yf, its claw -ff; middle toe T 6 2, its claw -ff .
