The birds of Java are distinguished for their variety and for the rich plumage with which they are adorned. During a single month passed in Ardjoeno, a mountain situated in the regency of Paseroean, in the east of the island, Mr. Wallace collected ninety-eight species of birds. Among these he mentions the Javan peacock, of which he obtained two specimens more than seven feet long; the jungle fowl (_Gallus furcatus_); the jungle cock (_Gallus bankiva_), called by the natives bekéko; various species of woodpeckers and kingfishers; a hornbill (_Buceros lunatus_) more than four feet long; and a "pretty little lorikeet (_Loriculus pusillus_) scarcely more than as many inches." When he visited the west of the island, he found still more valuable specimens in the Preanger regencies, twenty miles south of Buitenzorg. Among the mountains of this neighbourhood, and at an elevation of 4000 feet, he collected in a fortnight forty species of birds, "almost all of which were peculiar to the Javanese fauna." In these were included the "elegant yellow-and-green trogon (_Harpactes Reinwardti_); the gorgeous little minivet flycatcher (_Pericrocotus miniatus_), which looks like a flame of fire as it flutters among the bushes; and the rare and curious black-and-crimson oriole (_Analcipus sanguinolentus_)." Mr. Wallace also speaks of the rare and beautiful butterflies which he captured here. In particular he secured a specimen of the calliper butterfly, "remarkable for having on each hind wing two curved tails like a pair of callipers." It is in this neighbourhood that the large Javan wood-pigeons which I saw at Tji Wangi are to be found. As they are excellent eating, they are shot by the planters, though it is often difficult to get within range of them owing to the height of the rosamala trees in which they settle. There are certain characteristic developments of plant-life which arrest the attention of the traveller in Java.
