" The zoogeographical relationship of the Philippines and Celebes, as exemplified by their birds, has been adverted to by Mr. Wallace and other writers. Unfortunately the Philippine archipelago, with its twelve hundred islands, bas been but imperfectly explored ; while the localities of many, if not of all the known Philippine species are but vaguely ascertained. Luzon, the island whose ornithology has been the most investigated, is the furthest off from Celebes, and has the large island of Mindanao and many of less importance intervening. The resemblance which exists between the Celebean and Philippine avifaunas rests on the occurrence of Papuan genera in Mindanao, and perhaps iu South Luzon, which likewise occur in Celebes: Cacatua, Cyclopsitta, Tanygnathus, Phlegoenas*, Hemiphaga, and Megapodius may be cited. Two genera seem to be confined to Celebes and the Philippines-Prioniturus and Pyrrhocentor; this last is only known from Mindanao. Megapodius cumingi (Gould) is stated by Camel (v. Martens, op. cit.) to be found at Tabon in Mindanao and in Mindoro. The exact habitats of the other genera remain to be determined. The known Philippine genera of the Picariee and Passeres are nearly all Indo-Malayan ; but then they have mostly been as yet only obtained from the neighbourhood of Manilla. They include characteristic Indian genera unknown in Celebes. Such are, besides Hierax, Harpactes, Chrysocolaptes, and several other Picidee, Xantholeema, Irena, Copsychus, Cittacincla, Tchitrea, Ixos, Hypsipetes, Parus, and genera such as Lanius and Turdus. " That Mindanao contains a strong Indian element, however, is shown by the fact that Xantholeema, Irena, and Copsychus have been there obtained; Irena also occurs in the island of Panay. Thus enough is known of the Philippine ornis to justify anticipation, when worked out, of highly interesting zoogeographical facts, but * Phlcgcenas luzonica (Scop.), = cruenta (Gm.), is said by Bureta to occur in the Calamines (conf v. Martens, J. fiir O. 1866, p. 25). |
