130 JAN PIETER VAN WICKEVOORT CROMMELIN. 



Ornithologists may be called to the following: 



Milviis migrans (Bodd.). 



Turdus obscurus Gm. juv.; Oct, 21^^ 1843, near Haarlem. 



Anthus richardi Vieill. cT juv.; Oct. 24th 1890, The Hague. 



Loxia bifasciata (Brehm), two males ; North Holland. 



Ardea ralloides Scop, adult; July 1830, Schollevaers Eiland. 



Ibis falcinellus (L.), Q jun.; Oct. 30*^ 1873, Overijsel. 



Otis tarda L. male; March 7*^ 1855, Dordrecht. 



Otis tetrax L. two females, shot on, December 28tli 1853 

 in Gelderland , and January 28^^ near Alkmaar. 



Rallus parvus Scop, (ƒ juv.; September 9*^ 1872, Overijsel. 



Nutnenius tenuirostris (Vieill.), male ; December 5tii 1856, 

 near Haarlem. 



Fuligula rufina (Pall.), five specimens from the Naarder 

 Meer near Amsterdam. 



Moreover, as hardly need to be said, his collection con- 

 tains whole series of Ampelis garrula, Nucifraga caryo- 

 catactes , Syrrhaptes paradoxus and others , all obtained 

 during their respective invasions in the Netherlands. 



A complete list contains ample informations about each 

 of the specimens obtained. His collection has furnished a 

 great number of facts mentioned in » Bouwstoffen vooreene 

 Fauna van Nederland", and many valuable contributions 

 from his hand are contained in the » Archives Neerlandaises" 

 and in »Nederlandsch Tijdschrift voor de Dierkunde", while 

 many of his most interesting observations have been re- 

 corded by Dr. Herman Albarda in his annual reports (Or- 

 nithologisch Jaarverslag) which are published in » Tijdschrift 

 der Dierkundige Vereeniging". 



Crommelin was much interested in the occurrence of h y- 

 brids, especially among Ducks, and several very interest- 

 ing cases of interbreeding were treated of by him in the 

 above mentioned periodicals. 



The value of all that has been done by this zealous 

 Ornithologist will , however , be enhanced when we consider 

 that , already during his academical studies , he suffered much 

 from a disease of his eyes , which rapidly became worse ,
