AVIFAUNA 



a young male without date, captured near Rotterdam and 

 presented by H. Schlegel (Schlegel, Cat. Anseres, Anser 

 rujicollis, n°. 2). 



39. Branta leucopsis (Bechstein). [Brandgans]. 



The Museum received a young female shot 1 February 

 1907 on Texel, and one old male, two old females, two 

 young males and a young female shot on the Ooster Schelde, 

 Zeeland, 2 March 1907, and presented by the late Mr. T. 

 M. Pike. 



Though not a wild shot bird, yet I will mention here 

 the interesting hybrid between Branta leucopsis and Anser 

 albi frons, bred in the Zoological Garden at Amsterdam, 

 preserved in our collection (Schlegel, Cat. Anseres, Anser 

 leucopsis, n°. 8). 



40. Branta bernicla (L.). [Rotgans], 

 We received 17 specimens. 



41 . Branta bernicla glaucogaster (Brehm). [Witbuikrotgans]. 



Of this light-bellied form we possess three specimens 

 killed in our country, all three adult ones with no white 

 or whitish edging to the wingcoverts, viz. : 

 9, labelled only Holland (Schlegel, Cat. Anseres, Anser 



bernicla, n°. 4) ; 

 9, 20 February 1861, Overijssel (Schlegel, ibid. n°. 5); 

 9, 2 February 1801, Wieringen (Collection van Wickevoort 



Crommelin, 235 — 4). 



42. Branta canadensis (L.). [Canadagans]. 



In the collection are two adult males, which have been 

 shot 22 July and 28 July 1876 in the Anna Paulowna- 

 polder, province Noord-Holland, and which are presented 

 by Jhr. Mr. D. van Foreest. The bird is observed on several 

 occasions in our country, but it is doubtful whether these 

 are real wild birds or such escaped from captivity.
