144 Notices and Descriptions of various New [Feb. 



a quarter. Upper-parts greenish olive-brown, with a dull whitish 

 supercilium ; chin, and generally the medial portion of the throat, with 

 the belly and lower tail-coverts, white ; breast and flanks brownish- 

 fulvous, brighter in old males ; the throat and fore-neck streaked 

 laterally with olivaceous, which in some specimens crosses the breast 

 above the fulvous hue, and is more or less ashy ; others again, evidently 

 the old males, have the entire crown and neck all round, of a dusky-ash 

 colour, mingled with white on the middle of the throat. Bill dusky 

 above, the basal two-thirds of the lower mandible yellow ; and legs pale 

 brown. The wings of this species are firm and acuminate, and the tail 

 also is firm. It inhabits the eastern coast of the Bay of Bengal, from 

 Arracan to the Straits of Malacca, becoming more numerous south- 

 ward ; and M. Drapiez mentions having received it from Java, where 

 it is a periodical visitant, and named (as he informs us) Striee. 



11. T. unicolor, Tickell, J. A. S. II, 577 ; also of Gould, P. Z. S. 

 1837, p. 136. Length about nine inches, of wing four inches and five- 

 eighths, and tail three and a half ; bill to gape above an inch ; and tarse 

 exceeding an inch and one-sixteenth. Colour uniform dark ashy above, 

 paler below, and passing to white on the belly and lower tail-coverts ; 

 a tinge of rufous on the fore- part of the wing underneath. Bill yellow ; 

 and legs duller yellow. Capt. Tickell describes the female to be 

 " dirty-grey, mixed on the back with olive, tinged on the head with 

 brown. Wings and tail brownish ; coverts of tail iron-grey ; breast 

 isabella-grey, belly white." What Mr. Gould describes as the young, 

 appears to me to be the female of the next species : and he also states 

 the bill and legs to be livid fuscous : the length of wing he gives, " three 

 inches and a quarter," must be a misprint for five and a quarter ; though 

 that would exceed, by more than half an inch, the length of wing of the 

 only specimen before me. The species inhabits the Himalaya chiefly, 

 but occurs sometimes in central India. 



12. T. dissimilis, nobis : T. unicolor et T. modestus, nobis, passim, 

 as in XI, 460, &c. : Calcutta Thrush, Latham, the female. This 

 bird, as well as the preceding one, is very closely allied to the suc- 

 ceeding group, Geocichla ; and the mature male of the present spe- 

 cies has the whole under-parts from the breast, except the medial line 

 of the belly and the lower tail-coverts, which are pure white, of the 

 same bright ferruginous colour as in G- citrinus, G. cyanotus, fyc.
