The very extensive collection of stuffed Dutch birds 
collected by this gentleman were given after his death in 
1891 to the Leyden Museum as he had expressely desired. 
Those of A. A. van Bemmelen published in the Bouw- 
stoffen, Il, p. 2, 1856, bl. 119—130. On birds observed 
on the island Rottum. Idem in Jaarboek van Natura Artis 
Magistra, 1856, bl. 131—141. Birds observed on the coast

For birds occurring in the North, especially in Friesland 5), 
the publications of H. Albarda are of great interest, who 
also has given at irregular intervals in the Tijdschrift der 
Dierkundige Vereeniging, accounts of rare birds observed 
in the Netherlands at different periods *). 
Besides the mentioned publications some others of less 
importance appeared chiefly treating local questions — and 
amongst them I must not forget two interesting papers 
1) H. Albarda. Naamlijst der in de provincie Friesland in wilden staat 
waargenomen vogels. Bouwst. III, stuk 4, 1866, pp. 298—333. 
2) See also Journal für Ornithologie, XXXX Jahrgang, Heft IV, pp. 417 et
