THE BIRDS OF THE ANAMBA ISLANDS.

INTRODUCTION. 
Dr. W. L. Abbott was the first ornithological collector to visit the 
Anamba Islands of the South China Sea. Accompanying him was 
Mr. C. Boden Kloss, who later published an account of the cruise 
with a nominal list of the birds of these islands.1. This trip was 
made in the summer and autumn of 1899. During the summer of 
the following year Doctor Abbott again visited these islands. As 
one of the results of these two excursions Doctor Abbott sent back to 
the United States National Museum a collection of 212 birds, repre- 
senting 44 species and subspecies, which has proved to be of much 
interest. 
The following report on the avifauna of the Anamba Islands is 
based entirely on Doctor Abbott’s specimens, his manuscript notes, 
and the data published by Mr. Kloss.?, Nineteen new subspecies are 
here described from the Anamba Islands in addition to the two 
hitherto published.* Two others—one from the Seychelles, the other 
from the Andaman Islands—are also named incidentally in the fol- 
lowing pages.‘ 
In the preparation of this contribution the writer has enjoyed the 
facilities of the United States National Museum, and the cordial 
cooperation and assistance of the assistant curator of the Division 
of Birds, Dr. Charles W. Richmond. The writer is also personally 
indebted to Doctor Abbott for geographical and other information 
concerning the Anamba Islands. 
All measurements are in millimeters, and have been taken as 
explained in the writer’s recent paper on Butorides virescens.> The 
names of colors employed in the descriptions are based, except where 
otherwise stated, on Mr. R. Ridgway’s recently published Color
