20. Garzetta garzetta (L.). [Kleine zilverreiger]. 



This species is not represented in the collection by an 

 example shot in our country. One indigenous example was 

 preserved in the University Museum of Groningen, burnt 

 in 1906; another was killed in July 1901 near Gennep, 

 province Limburg (Snouckaert, Tijdschr. Ned. Dierk. Vereen. 

 VII, 1902, p. 271). 



21. Nycticorax nycticorax (L.). [Kwak]. 



The night-heron is at the present time very rare in 

 Holland. We possess three specimens : an adult one, only 

 labelled »Holland" (Schlegel, Cat. Ardeae, Ardea nycticorax, 

 n°. 1), a young male, shot in September 1849 in Holland, 

 without exact locality (Schlegel, ibid. n°. 2) and a young 

 male killed 19 August 1861 in the province Zuid-Holland 

 (Coll. van Wickevoort Crommelin, 218 — 3). 



22. Ardeola ralloides (Scopoli). [Ralreiger]. 



Two specimens are in our collection : an adult specimen, 

 shot at the Kralingermeer near Rotterdam, purchased from 

 the Cabinet van Lidth de Jeude (Schlegel, Cat. Ardeae, 

 Ardea comata, n°. 1) and an adult one, shot on the Scholle- 

 vaarseiland, July 1860 (Coll. van Wickevoort Crommelin, 

 215—1). 



23. Ardetta minuta (L.). [Wotjdaapje]. 



In the latter years the Museum received four specimens: 

 young cf, 14 August 1906, Kagermeer, prov. Zuid-Holland ; 

 adult Q, 25 September 1906, Aalsmeer, prov. Noord-Holland ; 

 adult Q, 15 August 1907, Leimuiden, prov. Zuid-Holland ; 

 young (ƒ , 7 August 1908, Zoeterwoude, prov. Zuid-Holland. 



24. Botaurus stellaris (L.). [Roerdomp]. 



It is a remarkable fact, that among the specimens pre- 

 served in our collection are much more males than females.
