Dr. W. L. Abbott's first collection of birds from Simalur Island 

 was made during the latter part of the year 1901. This island, Avhich 

 is about 55 miles long and well forested, lies somewhat less than a 

 hundred miles off the western coast of Sumatra, and about 200 miles 

 from the northwestern end. It is one of the Barussan Islands, which 

 extend along the western coast of Sumatra ; and the accompanying 

 map ^ shows its relative position. The birds obtained by Doctor 

 Abbott on his first visit have already been listed by Dr. C. W. Rich- 

 mond, and a number of novelties described.^ 



On his second trip Doctor Abbott remained about a week, from 

 October 21 to October 26, 1902, most of this time at Sibabo Bay. The 

 ornithological results consisted of 70 specimens of birds, represent- 

 ing 38 species. All the new forms, with one exception,^ have already 

 been described.* Two species, Macroyygia eniiliana hypopercna 

 Oberholser, and Treron curinrostra haliploa Oberholser, are actual 

 additions to the avifauna of this island, and these, together with 

 those already recorded by Doctor Richmond,^ make a total of 79 

 species of birds now known to occur on Simalur Island itself, not 

 counting the neighboring islets of Pulo Asu and Pulo Siumat. 



All measurements in this list have been taken in millimeters, 

 after the manner described in the writer's paper on ButoTides vires- 

 cens.^ In a number of cases, particularly those of recently named 

 iubspecies, the measurements given have not been confined to speci- 

 mens in the present collection, but, for the sake of completeness, have 

 been exteiided to all the adult Simalur Island birds in the United 

 States National Museum. The names of colors are from Mr. Ridg- 

 way's Color Standards and Color Nomenclature.
