AVIFAUNA 



A male, shot 18 November 1864 in the province of Noord- 

 Holland, making part of the Collection van Wickevoort 

 Crommelin (294 — 5) is interesting by the pale coloration 

 of the upper parts. 



2. Podiceps grisegena (Boddaert). [Roodhalsfuut]. 



Since 1904 we received only three specimens, killed in 

 the neighbourhood of Leiden, being an old male and an 

 old female from the Kagermeer, 22 September 1905, and 

 a young female from Zoeterwoude, 16 October 1906. 



3. Podiceps auritus (L.). [KuifduikerJ. 



In the latter four years the Museum received three spe- 

 cimens in winter plumage, killed in the vicinity of Leiden, 

 viz. : cf , 24 January 1905, Nieuwkoop ; 9> 19 October 1905, 

 Kagermeer; Q, 15 November 1907, Zoeterwoude. In our 

 collection are five specimens in full summer dress: four in 

 the collection van Wickevoort Crommelin (296 — 1, 3, 5 and 

 8) and one in our old collection, presented by the late van 

 Wickevoort Crommelin in 1856 (Schlegel, Cat. Urinatores, 

 Podiceps cornutus, n°. 2). 



4. Podiceps nigricollis Brehm. [Geoorde fuut]. 



This species the Museum did not receive in the latter 

 years. We possess altogether ten specimens from Holland, 

 among which are four specimens in full summer plumage, 

 two in the collection van Wickevoort Crommelin (297 — 1 

 and 3) and two in our old collection (Schlegel, Cat. Urina- 

 tores, Podiceps auritus, n<>s. 2 and 3). 



5. Podiceps fluviatilis (Tunstall). [Hagelzakje]. 



We received 13 specimens, only one in breeding plumage. 

 Of this species, our commonest grebe, the Museum possesses 

 only very few examples in full dress, altogether only six. 

 Specimens in this dress from Holland are very welcome 

 to our collection.
