116 MR. G. A. BOULENGER ON THE [Mar. 6, being black ; the wings, the tail, and the preocular spot are black ; the upper wing-coverts are black with a scarlet band on the outer webs nearly in the middle, but not extending to the extremity of the feather ; the inner margins of the remiges are white ; the irides are rich brown ; the edges of the lower maxilla yellow ; tongue yellow ; legs and feet yellowish green ; soles yellow. The young male is at first almost entirely greyish brown ; the throat is pale grey ; but quite below the maxilla and under the eyes the orange-red colour indicates the coming scarlet ; the back is greyish brown, but of a deeper colour in the uropygial region ; the wings and the tail are brownish grey ; the breast and under tail-coverts greenish fulvous ; the margins of the upper wing-coverts pale fawn-colour with, in some lights, reflections of red ; the margins of the remiges are olive-grey; the throat, the front of the, head, the breast, and the uropygial region are the first to assume the scarlet colour of the adult ; the angle of the wing has a dirtj-white spot, which, with the olive-grey margins of the remiges, are the last to change to black. The description of M.pusilla, as given on page 276 of the P. Z. S. for 1879 by Mr. W. A. Forbes, might apply to the bird under remark ; but as I have access to no library here, and have no speci-mens with which to compare my skins, I have not the means of satisfactorily determining them. Should this turn out to be a new species, it might bear the name of Myzomela wakoloensis. At all events I am happy in being able to extend our knowledge of the distribution of this lovely genus to the Ceram group. Amboina, December 1.5, 1882. 4. On the Geckos of New Caledonia. By G. A. BouLENGER, F.Z.S. [Eeceived February 26, 1883.] (Plates XXI. & XXII.) The object of this paper is to serve as a guide to the identification of the Geckonidse of New Caledonia, and to put order into their synonymy. As may be seen from the following bibliographical list, a good deal has been written on the subject before ; but, in their endeavours to identify the species described by them with those de-scribed by M. Bavay, the subsequent autliors have in many cases added to the confusion. Having, through the kindness of Messrs. Bavay, Barboza du Bocage, and Sauvage, enjoyed the advantage of studying the typical specimens described by those gentlemen, which seemed to require reexamination, I have arrived at such results as will be of some use to the student of the New-Caledonian fauna and to herpetologists generally ; for a glance at the synonymies of the species will show how great was the confusion. Without bringing together and comparing carefully the typical specimens in the museums of
