38 ON BIRDS FROM THE NETHERLANDS, 
hunting-department of the province Zuid-Holland, on Fe- 
bruary 7th, The Museum loses in him one of its best friends, 
one, who had the Museum’s interests at heart, wherever 
he could. Warranted by H. M. the Queen he opened the 
royal demesne to science and enriched our collection of 
native birds with many specimens. This sad loss will be 
felt by us long time. 
In the following lines I enumerate the more important 
additions to our collection of indigenous birds. 
Podiceps auritus (L.). 
An adult male in perfect plumage, shot 10 April 1911 
at Anna Paulownapolder, province Noord-Holland, was 
purchased for our collection. This is the first adult speci- 
men I receive after seven years collecting. 
Podiceps nigricollis Brehm. 
Also of this grebe, I received a male in full plumage, 
caught 3 April 1911 at den Helder, the first specimen in 
this plumage since 1904. A female in winter plumage was 
shot 28 October 1910 near den Helder and sent to the 
collection. 
Fulmarus glacialis (L.). 
An adult female, caught 13 November 1910 at Horn- 
huizen, province Groningen, has been purchased for our 
collection. 
Oceanodroma lIeucorrhoa (Vieillot). 
This species has visited us last winter in rather large 
number. The first example, a female, I received 29 Sep- 
tember from Texel, where it had been caught the day 
before; in October, November and December I received 6 
other examples from the coast of Groningen. 
Casarca casarca (L.). 
A male, the second specimen known from the Nether- 
Notes from the Leyden Museum, Vol. XXXIV.
