NOTE VIII. 
REPORT ON BIRDS FROM THE NETHERLANDS 
RECEIVED FROM 1 SEPTEMBER 1910 
TILL 1 SEPTEMBER 1911 
BY 
Dr. E. D. VAN OORT. 
The increase of the collection of indigenous birds of the 
Leyden Museum during the last twelve months was an 
important one. Not less than 787 skins and more than 
800 eggs in clutches have been added to the collection. 
Among the skins there are again some very interesting species 
such as: Megalestris skua, Cepphus grylle, Casarca casarca, 
Picus martius, all rare birds in our country. 
I have the pleasure to mention the following gentlemen, 
who presented our collection with more or less interesting 
examples: F. E, Blaauw, J. Boonstra, C. de Bruyn, A. Burdet, 
C. F. H. Dumont, R. van Eecke, Jhr. W. C. van Heurn, 
C. J. van der Klaauw, A. Kohlbeck, P. de Koning, E. Loeb, 
Mr. H. A. Lorentz, M. van Mens, H. M. Rose, Jhr. F. de 
Roy van Zuidewijn, B. Scheelings, Dr. H. E. Th. van Sil- 
levoldt, Ch. van Spall, G. S. van der Spruyt, the late 
C. N. Tieleman, F. A. Verster van Wulverhorst, F. H. 
Verster and J. C. Wäkerlin; more special thanks are due 
to Messrs. R. van Eecke and Jhr. W. C. van Heurn, the 
first presented to the Museum a fine collection of indigenous 
birdskins, 93 specimens belonging to 55 species, the second 
enriched the Museum with a collection of about 460 eggs 
in clutches of native birds. 
With much regret I have to record the decease of Mr. 
R. Baron van Zuylen van Nyevelt, master of the Royal 
Notes from the Leyden Museum, Vol. XXXIV.
