308 MR. R. B. SHARPE ON BIRDS COLLECTED BY 



Indian village of Dumalon in the same province. The island of Basilan, lying between 

 Mindanao and the Sooloo group, was next visited ; and here he stayed two weeks, after 

 which he returned to Zamboanga, and thence to Manila. In the month of December he 

 again went south, stopping at Ilo Ilo, on the island of Panay, and visiting the mountains 

 in the interior. After a short stay at the neighbouring island of Guimaras he crossed 

 over to Negros, journeying on horseback round the north end of the island; thence in a 

 native boat he traversed the sea to Zebu, which he crossed, till he arrived at the town of 

 the same name, where he took horse again and rode southward, crossing the island once 

 more and passing over the strait to the town of Dumaguete, on the island of Negros. 

 Dr. Steere then went back to Zebu and crossed to the island of Bohol ; after passing 

 round part of this island he returned to Zebu and afterwards to Manila, where he 

 visited the Negritos on the north side of the Bay of Manila, leaving finally in April for 

 Singapore." 



In the preparation of this paper I have followed, as far as possible, Lord Tweeddale's 

 memoir, in order to make it supplementary to the latter ; and, before commencing the 

 detailed account of the species, it may be as well to compare the results obtained by 

 Dr. Steere with those recorded by Lord Tweeddale in 1875. 



The number of birds included by the last-named author was 219. From this total 

 I am only aware of one species that should be deducted, viz. Circus ceruginosus. For 

 this error I myself am responsible, as I recorded in the ' Catalogue of Birds ' a young 

 Marsh-Harrier, which I have since come to the conclusion is only an immature Circus 

 spilonotus (cf. Sharpe, ' Ibis,' 1876, p. 30). Dr. Briiggemann has added a Pitta from 

 Luzon, in the Darmstadt Museum. 



The result of Dr. Steere's expedition has been to add more than sixty species to the 

 avifauna of the Philippines ; and by restoring to its position as a species Dicceum papuense 

 from Mindanao, and by adding the few birds known from the Sulu Islands, we have now 

 a total of 286 Philippine species. The following remarks give some idea of the actual 

 alterations made in our knowledge of the different islands. 



Philippine Islands. 



In the above-mentioned paper of Lord Tweeddale's no less than 57 species are cata- 

 logued as being of Philippine origin, without any exact locality being known for any of 

 them beyond the above vague habitat. I am able to reduce this number by eight, as 

 follows : — 



1. Circus ceruginosus is C. spilonotus, juv. 



2. Brachyurus erytlirogaster is from Luzon (Mus. J. Gould). 



3. Zeocephus rufus is from Luzon (Mus. Brit.). 



4. JPadda oryzivora is from Mindanao (Steere). 



5. Sturnia violacea is from Negros (Steere). 



6. Calcenas nicooarica is from Mindanao (Steere). 



7. Ortygometra cinerea is from Zebu (Steere). 



8. Gorsachius melanolophus is from Mindanao (Steere).
