Show 408 DR. O. FINSCH ON BIRDS FROM [May 1, number altogether 10 species. One of these, a Kingfisher, although known already to Forster, proves to belong to an unnamed species. A closer exploration of the group will probably bring to light further species, peculiar to the different islands, such as, under similar circumstances, the excellent researches of Mr. Layard have recently made known to us in the Feejee group. 1. COLLOCALIA CINEREA (Gm.). Herse Forsteri, Hartl. C. vanicorensis, part., Finsch & Hartl. Orn. Central-Polyn. p. 47. One specimen, agreeing generally with the description communicated to me by Dr. von Pelzeln from a Tahitian specimen in the Vienna Museum (vide Journ. d. Museum Godeffroy, Heft xii. 1876, p. 25); but the coloration is as dark as in C. vanicorensis; the rump is not pale, as in C. spodiopygia, but uniform with the remaining upper parts; the single feathers show very narrow light lateral margins ; but these are hidden. The specimen seems, therefore, to be identical with the Tahitian species first mentioned from this locality by Forster, and agrees exactly in its larger size, by which it may be distinguished from the other species inhabiting the Pacific. 2.

Head, neck, mantle, and whole under surface, including the under wing-coverts, white; shoulders, lower back, quills, and tail cobalt-blue; inner webs of wings smoky black, margined with white ; from the lores through the eye and temporal region a narrow black band encircling the nape; basal half of bill black, lower mandible pale horn-colour ; feet black. There are three specimens which agree perfectly with the description above given. The white middle portion of the mantle is faintly stained with rusty. Young. Frontal margin, extending as a narrow supercilium to above the eye white; remainder of head obscure marine-blue (on the crown appear three new pure white feathers); lores and a broad band around the nape dull black, the same as the hind neck and upper portion of the mantle; on the hinder mantle some white feathers, washed with pale rusty; under surface white, with dark edgings to the feathers of the sides of the crop ; smaller upper wing-coverts with narrow whitish tips.
