AVIFAUNA 



310. Chrysomitris spinus (L.). [Sijsje]. 

 8 specimens. 



311. Passer domestica (L.). [Huismusch]. 



17 specimens, among them a pure albino, a male, killed 

 23 August 1905 on Texel and a melanistic form, a female, 

 killed 20 November 1905 in Leiden, in which the whole 

 plumage is much darker than usually. A male, labelled only 

 Holland, has the black patch on throat and breast mixed 

 with brown. 



312. Passer montana (L.). [RingmuschJ. 



11 specimens. In the collection van Wickevoort Crom- 

 melin is a male (132 — 1) shot November 1850 in our 

 country, exact locality not mentioned, that is very pale, 

 strongly resembling the subspecies Passer montana dilutus 

 Richmond from Turkestan. A female in the same collection 

 (132-5) shot 23 October 1860 at Overveen, Noord-Holland, 

 has the same light coloration. A male, caught 21 October 

 1867 (Coll. van Wickevoort Crommelin, 132 — 7) has the 

 feathers of back and wings whitish with ferruginous ed- 

 gings; the tail is whitish, the head normally coloured. A 

 young female in our general collection, caught November 

 1860 near Rotterdam and presented by Mr. J. G. Keulemans 

 is very pale in coloration and variegated with white. An 

 adult specimen, labelled only „Holland", purchased in 1866 

 from the Cabinet van Lidth de Jeude has the head a little 

 paler than normally, the black markings on earcoverts and 

 throat brown, the uppersurface pale brown with ferru- 

 ginous margins to the feathers. 



313. Petronia petronia (L.). [Rotsmuscb]. 



We possess a young specimen, without sex, labelled only 

 Holland, that is purchased in 1866 from the Cabinet 

 van Lidth de Jeude. It is very probably the bird, mentioned 

 by Schlegel as having been caught near Harderwijk, 

 Gelderland.
