AVIFAUNA 



for our Museum. Altogether we possess 10 specimens killed 

 in our country and also a skeleton of a specimen shot in 

 Holland. 



Gallidae. 



95. Perdix perdix (L.). [Patrijs], 



We purchased 17 specimens from different localities. We 

 possess 8 colour-variations of this species, all killed in 

 Holland: two almost white ones, a grey one in which the 

 brown colour is replaced by pale brown and yellowish 

 white, a dark maroon one with pale brown head, a pale 

 brown one, a pale brown one variegated with white and 

 two specimens strongly variegated with white. A male, shot 

 18 September 1861 in the province of Groningen, is very 

 dark at upper- and undersurface ; chin and throat are 

 however paler as usually. 



96. Caccabis rufus (L.). [Roode patrijsJ. 



This species has been observed in Limburg and Gelder- 

 land. As it has been introduced in some parts of Germany, 

 it is not certain, that the birds observed in our country 

 really were wild birds. We don't possess examples shot in 

 the Netherlands. 



97. Coturnix coturnix (L.). [Kwartel], 



We received only one specimen, a female, killed 26 October 

 1907 on Texel. 



98. Lyrurus tetrix (L.). [Korhoen], 



We purchased five specimens killed in the province 

 Drenthe. In January 1886 the late Mr. H. Albarda pre- 

 sented to our collection a female of the grey variety, in 

 which the rufous colour is wanting ; this bird has been 

 shot 31 December 1885 at Noordwolde, province Friesland.
