In Amsterdam Mr. Sclater was much interested to find an adult male and a young female of the fine Antelope Tragelaphus gratus, described by him in the Society's ' Proceedings ' for 1883 (see P. Z. S. 1883, p. 34, pi. viii.), remarkable for its long extended hoofs. These animals were named in Amsterdam Tragelaphus decula, but were certainly not, in Mr. Sclater's opinion, Antilope decula of Riippell (Neue Wirb. i. p. 11, t. iv.). They had been received from a correspondent on the Lower Congo. Other fine species represented in the Amsterdam Gardens were Canis jubatus of Brazil, Pedetes caffer of South Africa, Felis servalina, Ogilby (cf. Sclater, P. Z. S. 1874, p. 495, pi. lxiii.), from the Congo, and Corythaix livingstoni, G. R. Gray. Mr. Sclater had also paid a visit to the private garden of Heer Blauuw, at Westervald, near Hildersum, and inspected with great pleasure the herd of Gnus (Catoblepas gnu) recently spoken of by that gentleman in a communication to this Society (supra p. 2), and the other beautiful specimens in that collection. Mr. E. T. Newton, F.Z.S., exhibited a tibio-tarsus of the large extinct bird Gastornis klaasseni from the Woolwich Beds of Croydon. The specimen had parts preserved in it which were wanting in the type (described, Trans, vol. xii. p. 143), and consequently the length of the bone was now made certain. The following papers were read :- 1. Remarks on the Zoo-geographical Relationships of the Island of Palawan and some adjacent Islands. By A. H. E V E R E T T , C.M.Z.S. [Eeceived March 15, 1889.] (Plate XXIII.) It has been customary heretofore to regard the Island of Palawan, together with Balabac and the numerous smaller islands which lie between South Balabac and the Mindoro Straits, as forming a kind of debatable land, of which the fauna was not sufficiently well known to allow of its being allocated definitely to the Philippines or to Borneo and the more typical sub-area of the Indo-Malayan Sub- Region. But in actual practice these islands have been treated as a part of the Philippine sub-area by the authors who have written on the zoology of the latter, though until lately this practice was followed simply for reasons of conveniei ce, and not as expressing the opinion that their natural zoo-geographical relationship lay with that group rather than with Borneo. Quite recently, however, Professor J. B. Steere, to whom we are |
