an asterisk (one of them on only the Nyamok Islets), which were 

 merely seen. Aside from the two endemic forms, the known avifauna 

 of Pulo Taya appears not to differ from that of Lingga and other 

 neighboring islands. 



Doctor Abbott, accompanied by Mr. C. Boden Kloss, was appar- 

 ently the first ornithologist to examine Pulo Taya. Keferences in 

 literature to its birds, therefore, are confined to papers mentioning 

 the results of this expedition. 



Mr. Kloss has published a popular account of the trip,^ in which 

 he mentions some birds ; and the present writer has described a sub- 

 species of Sauro2)atis chloiis from Pulo Taya specimens.^ 



I am indebted to Doctor Abbott for physiographical and other 

 notes concerning the islands here treated ; and to Dr. C. W. Richmond 

 for other assistance. 



Measurements in this paper are all given in millimeters, and have 

 been taken as explained in the author's paper on Butorides virescem.^ 

 The names of colors are from Mr. Eobert Ridgway's recently (1913) 

 published Color Standards and Color Nomenclature. The locality 

 of all specimens hereinafter treated should be understood as Pulo 

 Taya unless otherwise stated.
