LIST OF BIRDS COLLECTED BY MR. EMIL 
EISENHOFER IN NORTHERN SIAM. 
By NiLs GYLDENSTOLPE, B. A. 
The following list is based upon a collection of birds made 
in Northern Siam by Mr. Emil Hisenhofer, Divisional Engineer of 
the Northern Railway. The birds were collected chiefly at Pa Hing, 
Bang Buei and Koon Tan—all these places being situated along the 
line to Chiengmai. There are many interesting and very rare species 
in the collection, as will be seen from the list, and a number are 
quite new to the Siamese fauna. Most of the species have, however, 
been previously recorded from Burma, the Shan States and the adjoin- 
ing parts of French Indo-China. 
Owing to lack of literature with me in Siam, I have been 
unable to go deeply into the question of subspecies. I have, therefore, 
followed closely the classification given by Oates and Blanford in the 
Fauna of British India, except in the case of the Columbidae, where I have 
adhered to the nomenclature adopted by Mr. E. C. Stuart Baker in 
his recently published Indian Pigeons and Doves, which is the latest 
work on that Family. 
For the convenience of readers possessing the Fauna of British 
India, I have given the numbers in that work in brackets for each bird 
recorded therein. 
In 1913 Mr. Eisenhofer sent a large collection to the Museum 
at Hannover. By the courtesy of its Director, Professor Doctor A. 
Fritze, all the birds were handed over to me for identification and a list 
of these has been published in the Proceedings of the Museum, The 
species recorded in that paper are marked with an asterisk in the 
following list. 
Nearly all Mr. Hisenhofer’s specimens are in very good condi- 
tion and it is to be hoped that he will further add to his fine 
collection,
