Section IL CAGAYAN SULU. 



The island of Cagayan Sulu, lying, as it does, in an isolated 

 position in the Sulu Sea, is extremely interesting to the ornithologist. 

 Placed midway between Palawan and the islands of the Sulu 

 Archipelago, with which latter it should on no account be confounded, 

 it lies somewhat nearer to the coast of Borneo, from which, however, 

 it is distant over fifty miles. It is of purely volcanic origin, and 

 Admiral Keppel, so long ago as 1853, made us acquainted with its 

 curious crater-lakes. It is not, however, with its geological aspects 

 that we have to deal, but with its avifauna, which, I believe, has, up 

 to the present, remained completely unexplored. 



In April 1883 I visited the island in Mr. Kettlewell's yacht 

 ' Marchesa,' remaining for about a week, and nearly ten months later 

 we again touched there on our return voyage to Singapore. Although 

 I collected diligently on both visits, the results were singularly 

 meagre, and I do not recollect ever meeting with a locality so poor 

 in bird-life. This, however, is probably owing to the island being, 

 geologically speaking, of comparatively recent formation. The few 

 species that were obtained are interesting as showing a mixed Philip- 

 pine and Bornean ornis, with a decided preponderance of the latter.
