Show 1877.] THE ORNITHOLOGY OF THE PHILIPPINES. 817 Mr. Everett last May selected new ground, and proceeded to Butuan, on the Butuan river, in North Mindanao, and afterwards changed his station to Surigao, situated at the most northern point of the island, and then to Placer on the north-east side. At these three stations he collected eighty-one species of birds during part of the months of May, June, and July, and has thus largely added to our knowledge of the avifauna of this little-explored island. Mr. Everett in one letter states that his work has been much interrupted by the rains, in another that he has been working under numerous drawbacks-fever, constant heavy rains, and impossibility of getting regular supplies of ammunition. That, in spite of all his difficulties, he should have done so much, redounds all the more to his untiring zeal. To the total of fifty-nine known Mindanao birds Mr. Everett has added forty-three. Of these nine are new to science :- Tanygnathus everetti. Dicceum einereigulare. Mulleripicus fuliginosus. Mthopyga belia. Penelopides affinis. Anthothreptus griseigularis. Criniger everetti. Leucotreron ? incognita. Orthotomus nigriceps. Three are new to the Philippine avifauna: - Cisticola greyi. Limnocinclus acuminatus. AEgialites cantianus. One, stated doubtfully to occur in some Philippine island, was not included in m y list -.- Phlogcenas crinigera. The number of species of birds now recorded from the island of Mindanao amounts to 99, from south-west Mindanao 59, and from north-east Mindanao 81. The grand total of birds inhabiting the Philippine area (as restricted by me) has been increased by Mr. Everett's researches to about 288. 1. CACATUA H^MATUROPYGIA (1).
