ALLOTRIUS XANTHOCHLORIS. Yellow-green Allotrius. Pteruthius xanthochloris, Hodgs. in Gray’s Cat. of Spec. and Draw. of Mamm. presented to Brit. Mus. by B. H. Hodgson, Esq., App. p. 155.—Blyth, Journ. Asiat. Soc. Beng. vol. xvi. p. 448.—Gray and Mitch. Gen. of Birds, vol. iii. App. p. 13. App. to p. 270. Tuts bird, as well as the WJotrius melanotis, is an inhabitant of the little-known countries of Nepaul and Bootan; in the former of which countries the specimens contained in the collection of the Honourable East India Company were obtained by Mr. Hodgson. In Dr. Horsfield’s < Catalogue of the Birds in the Company’s Museum,” this species is regarded as the female of Wotrius eénobarbus ; but after a careful comparison of the two birds, I am induced to regard them as distinct, and to retain Mr. Hodgson’s name of wanthochloris for the one to which he assigned it, and which may be distinguished by its larger size, its more lengthened and lax plumage, more ample wings and longer tail, and a more uniform style of colouring. Nothing whatever is known of the habits and economy of this and the allied Species ; and as it is much to be regretted that such is the case, I trust that some one or other of the Company’s officers who may be favourably situated for investigating them, will give attention to the subject and duly record their observations. The habitat of this species and of P. melanotis would appear to be the region of the Tarai, at the base of the south-eastern Himalayas. Head grey ; chin and breast greyish white ; remainder of the plumage, including the tail, yellowish-green ; wings dark brown, edged with yellowish green; irides dark brown ; bill plumbeous ; feet flesh-white. The figures are of the natural size. The plant is the Lvora rosea of Dr. Wallich.
