232 ON BIRDS FROM THE NETHERLANDS, 
Phalacrocorax graculus (L.). 
A young female was shot at Voorschoten near Leiden, 
12 August 1912, and presented to our collection by Mr. 
G. S. van der Spruyt. 
Cygnus bewickii Yarrell. 
Bewick’s swan has been observed last autumn more fre- 
quently than was the case in other years. I received 5 speci- 
mens, old and young ones, shot in the last of October 
and in November in the eastern part of the Zuiderzee 
near Blokzijl. 
Branta bernicla (L.) [var. collaris (Brehm)?]. 
The form with light grey under parts and white vent, 
which occurs with the common dark form in Nova-Zembla, 
Kolguev and Spitsbergen (see O. Le Roi in A. Koenig’s 
Avifauna Spitzbergensis, 1911, p. 214), has been observed 
in January and February in several examples. I received 8 spe- 
cimens, 7 and QQ, shot in the last of January and the first 
half of February near Texel and on the coast of the province 
Friesland; five of them are very light on the under parts and 
quite agree with two examples in our collection from North 
America; the 3 other ones are darker, the colour of their un- 
der parts being between that of the light and the dark form, 
more approaching however that of the light form. 
Aythia nyroea (Güldenstädt). 
The Museum received two females shot 7 and 14 
September 1911, and a male shot 4 August 1912 at 
Nieuwkoop, province Zuid-Holland. 
Somateria mollissima (L.). 
An old (J in change was shot at Nieuwkoop 19 Novem- 
ber 1911 and purchased for our collection. I mention this 
capture, as the locality is tolerably far inland.
