PERICROCOTUS CINEREUS, Lay. Grey Pericrocotus. Pericrocotus cinereus, Lafr. Rev. Zool., tom. viii. 1845, p. 94.—Gray and Mitch. Gen. of Birds, vol. iii. App. p. 13, App. to p. 282. modestus, Strickl. in Proc. of Zool. Soc., part xiv. p. 102.—Ib. Ann. and Mag. of Nat. Hist., vol. xix. yp. 131, Tue Grey Pericrocotus is unquestionably the rarest species of the genus, there being few museums in which an example is to be found. It is a native of Lugon and the Philippine Islands, from the latter of which countries I have received it direct ; I also possess a specimen said to have been procured in Malacca, but this is by no means certain. In its structure and in the general disposition of its markings it is in every respect a typical member of the genus, while in the total absence of red or yellow colouring in either sex, it differs very conspicuously from every other that is at present known. I trust it will be found that I am correct in considering it identical with the P. cénereus of the Baron de la Fresnaye, and the P. modestus of the late Mr. Strickland, the former of which names is the one adopted on the score of priority. As is the case with the other species of this form, a marked difference occurs in the sexes; the female being destitute of the white forehead and of the jet-black back of the head and nape of the male; the sides of her breast and flanks are also more strongly washed with light grey; but, with the exception of these distinctions, they are very similar. The male has the forehead and frontal half of the crown, chin, throat, sides of the neck, breast, centre of the abdomen, vent and under tail-coverts white ; a narrow line at the base of the upper mandible, lores, hinder half of the crown, occiput and nape jet-black; back and upper surface grey; flanks grey; wings blackish-grey, with a V-shaped mark of white at the base of the primaries and secondaries, not very perceptible above, but broad and well defined on the under surface ; tail black, the central feathers edged with grey, and the lateral ones largely tipped with white; bill and feet black; irides dark brown. The female differs in having the head and upper surface brownish-grey, and the under surface dull white. The Plate represents the two sexes of the natural size. The plant is the Rhododendron Keysit.
