1877.] THE ORNITHOLOGY OF THK 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 cinei-eigulare. 

 Mulleripicus fuliginosus. ^thopyga hella. 

 Penelopides ujjinis. Anthothreptus griseigularia. 



Criniger everetti. Leucotreron? incognita. 



Orthotomus nigriceps. 



Three are new to the Philippine avifauna : — 



Cisticola greyi. Limnocinclus acuminatus, 



jEgialites cantianus. 



One, stated doubtfully to occur in some Philippine island, was not 

 included in my 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.
