NOTES ON AND ADDITIONS. TO De, B, D. VAN OORT’S 
LIST OF A COLLECTION OF BIRDS 
FROM WESTERN JAVA AND FROM KRAKATAU ') 
BY 
ED. JACOBSON. 
I may be allowed to furnish a few additional remarks 
concerning the above named list, which Dr. van Oort was 
so kind to prepare on a number of Javanese birds collected 
under my personal supervision for account of the Leyden 
Museum. 
The birds were for the greater part shot and the skins 
prepared by half-caste and native hunters, ED also sup- 
plied me with the native names. 
Some reserve must therefore be made as to the correctness 
of these names, as the people from whom I received this 
information were not always trustworthy. Rather than to 
show their ignorance or to disappoint me, they sometimes 
gave me names of their own invention, if the real name 
was not known to them. I have as much as possible avoided 
this source of errors, by making them repeat the names 
at different times and by obtaining, as a control, my in- 
formation from different persons. 
In the case of species which ‘are not of common occur- 
rence, it was rather difficult to get at the right names.
