Show 490 MR. P. L. SCLATER ON ANIMALS IN THE MENAGERIE. [May 16, to make a closer comparison between them and the bird recently described under the name above given from the specimen living in our Gardens. Fig- 1 • Head of Buceros subcylindricus. Buceros cylindricus is at once distinguishable by the peculiar form of the elevated casque, which is correctly figured by Temminck (Pl. Col. 521. fig. 2), and by the white tail being completely crossed by a black median band. Our bird, as regards the form of its bill, is, as shown by the sketch, much nearer to B. fistulator; but the culmen is more elevated than in B. fistulator, and the lower mandible not so strong. Moreover, in B. fistulator the culmen and tip and the base of the lower mandible are white; in our bird the whole bill is black. Again, in B. fistulator there are no signs of the terminal edgings on the crest, and the outer secondaries are black instead of white. As far as I can at present make out, B. subcylindricus is distinct from both of these and from every other described species. 28. CACATUA GYMNOPIS, sp. nov. W e have now placed next together in the Parrot-house three living specimens of three nearly allied species of the group of smaller white Cockatoos, the determination of which has caused me some little trouble, though they are obviously very distinct. In the first of these birds (fig. 2), purchased April 11, 1864, being one of the individuals described in m y notice, P. Z. S. 1864, p. 187, and figured pl. xvii., there is no trace whatever of red colour |
