ON THE CATALOGUE OF VROEG’S COLLECTION, 69 
is also very well described in the Dutch list of items on 
page 30 under the same name. 
For the matter of denomination the catalogue of Vroeg’s 
collection cannot be noticed in Zoology. It is only of some 
interest to the knowledge of the avifauna of Holland, f.i. 
on page 5 it is stated, that the nutcrackers were very abun- 
dant in the autumn of the year 1753, and on page 80 it 
is stated, that there is an example of Ardea alba in the 
collection, caught in the province Overijssel, and mention 
is made of another specimen, which was shot near Rot- 
terdam, 
Leyden Museum, November 1911.
