1847.] or Little Known Species of Birds. 123 



The Dimorpha? moniliger, Hodgson, Ann. Mag. N. H. 1845, p. 196, 

 would seem, from the description, to approximate the above species 

 in its markings. 



Zanthopygia, nobis. This is a genus of Chat-flycatchers, which 1 

 am not as yet prepared to approximate to any other. In the form of its 

 beak, it bears much resemblance to the Australian genera Eopsaltria 

 and Petroica (which branch off from Pachycephala*), and also to 

 the Pratincolce ; but of the two species to be described, the bill of the 

 first is vertically deeper than that of the second, which renders gene- 

 ralization more difficult, although the generic identity of the two 

 birds is unquestionable. Bill of mean length, acutely triangular as 

 viewed from above, or much narrower than in the more characteristic 

 Flycatchers ; its upper ridge angulated, and the tip of the upper 

 mandible incurved and emarginated : gape beset with fine hair-like 

 vibrissa?. Tarsi and toes moderately small and weak, the tarse as 

 long as the middle toe with its claw ; wings reaching half-way down 

 the tail, their first primary short, only a quarter the length of the 

 second, which is shorter than the fifth, the third and fourth being sub- 

 equal and longest. Tail of mean length. Plumage rather firm : the 

 males black above, with yellow rump and under-parts, and a large 

 white wing-spot. From Malasia. 



Z. leucophrys, nobis. Length about five inches, of wing two and 

 three-quarters, and tail an inch and three-quarters : bill to gape five- 

 eighths, and tarse barely five-eighths of an inch. Colour deep black 

 above, bright yellow below and on the rump ; a large wing-spot, continu- 

 ed along two-thirds of the outer edge of the largest tertiary, also a spot 

 before and over the eye, and the lower tail-coverts, pure white : bill 

 dusky-horn or blackish, and legs brown. The femalet differs widely 

 in being of a light olive-green above, tinged with grey, especially

f Muscicapa zanthopygia, A. Hay, Madr. Journ. No. XXX 4 , 162. The above 

 description of the female is from his lordship's specimen; and Lord A. Hay's brief ' 

 notice of the male in a foot-note, is from a specimen in the Society's museum, of 

 which I have had a description by me in MS. for two years at least. His lordship, 

 by a slip of the pen, referred to Dr. Cantor's fine collection of Malayan birds, as con- 

 taining the male he had seen. Dr. C. has only a female, which accords with the 

 description in the text, except perhaps in having the head less tinged with ashy.
