DUTCH AND ENGLISH BIRDS. 185 
I am indebted to Dr. Jentink for making accessible 
to me the extensive collections of the Leyden Museum to 
which of late the coll. van Wickevoort Crommelin has been 
added; to Mr. A. A. van Bemmelen for doing the same 
with the collection of the Zool. Gardens at Rotterdam and 
to Mr. Howard Saunders for looking over the British 
birds in this paper and making some personal remarks 
which are recognizable by the initials H.S. put in brackets. 
Part a. 
The publications on Dutch birds began about the year 
1752 when a latin paper more or less in the form of a 
catalogue was published by P. H. G. Moehring. 
This work was translated into Dutch and completed by 
A. Vosmaer who published it in the years 1764 and 1765. 
These two publications were nothing more than catalo- 
gues and very incomplete. The great book of Nozeman and 
Sepp published in 5 parts in the years 1770, 1789, 1812, 
1826 and 1829, with 250 coloured plates in large folio must 
be regarded as the standard work on Dutch Ornithology. 
This work not only gave a very accurate list of the 
birds up to that time observed in the Netherlands, but 
also a very good description of the birds themselves and 
their habits. 
In 1815 C. J. Temminck published the first part of 
his Manuel d’Ornithologie in which, besides remarks on 
the avifauna of Europe in general, much was published 
that was new on the Dutch species. 
In 1828 H. Schlegel followed with a paper on the mi- 
gration of Dutch birds, in answer to a question put by 
the Dutch Society of Sciences. 
Then come a few publications of less importance 
whereafter, in 1852, prof. H. Schlegel published his list 
of birds observed in Holland in a wild state ').

staat waargenomen vogels (Bouwstoffen voor eene Fauna van Nederland, bijeen- 
verzameld door J. A. Herklots).
