having the outer web cut out toward the end ; the first quill is longest, 

 exceeding by half a twelfth the second, which is one-twelfth longer 

 than the third, the rest rapidly graduated, the distance between the tip 

 of the longest or first primary and that of the first secondary being ele- 

 ven-twelfths of an inch ; all the quills are rounded, and there are only 

 nine primaries. Tail of moderate length, rather narrow, slightly 

 rounded, the lateral feathers two-twelfths of an inch shorter than the 

 middle, which are longest ; all the feathers acuminate. 



Upper mandible dusky brovra, its edges lighter, lower mandible 

 flesh-coloured, with the tip brown. Iris hazel. Feet and claws pale 

 flesh-coloured. The head, and neck all round, with a portion of the 

 breast, rather deep ash-grey, the throat paler ; a ring of yellowish- white 

 margining the eyelids, no dusky band on the loral space as in the other 

 species ; the back, scapulars, and rump are rich olive-green ; the breast, 

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

 excepting the sides, which are greyish-green. The wings and tail are 

 greyish-brown, the edge of the wing yellow, the first quill narrowly

Length to end of tail 5| inches, extent of wings 8 ; bill along the 

 ridge ^|, along the edge of lower mandible ?| ; tarsus {^ ; hind toe ^^, 

 its claw i'^ ; middle toe ||, its claw ||. 



Adult Female. The Female resembles the male in the upper parts, 

 but has the head of the same tint as the back ; the throat light yel- 

 low, the sides of the neck, and a broad band across its fore part, together 

 with the sides, brownish-yellow. The yellowish-white ring round the 

 eye is as conspicuous as in the male. 



The young male and female, represented in Plate CXXXVIII, 

 have been described with sufiicient accuracy at p. 228 of Vol. IT. 



This species diff"ers from the others in having the wings much longer, 

 the tarsus shorter in relation to the middle toe, the claws much more 

 slender and much less arched, and in the colours as above described. 



These three species, which are nearly allied to Sylma Trichas, and 

 with it may constitute a distinct genus or subgenus, dififer from each 

 other much in the same degree as the Wood Wren, Willow Wren, and 

 Chifi^-chafF of Europe diff"er from each other. Should they be referred 

 to the genus Trichas, they might be named and characterized as fol-
