68 ON THE CATALOGUE OF VROEG’S COLLECTION. 
The list of items contains on pages 1—32 the list of 
the birds (nos 1—322); on pages 32 and 33 there are 
mentioned some quadrupeds, on page 38 also three eggs 
of the ostrich, and the cabinets and drawers, in which the 
birds and the afterwards mentioned insects are placed; the 
insects are enumerated on pages 34—49. Page 50 is blank. 
The »adumbratiunculae” are paged separately and contain 
7 pages. 
In the Dutch (and also in the French) title there is 
only stated, that the collection has been brought together 
and that the specimens have been stuffed by Mr. A. Vroeg, 
not that he has written the Catalogue; further that the 
collection will be sold at the house of Mr. Koster at the 
Hague by Mr. Pieter van Os, bookseller at that place, at 
October 6th 1764. The author of the catalogue, the list of 
items, is unknown and this is an important fact, as in the 
dutch list of items, preceding the »adumbratiunculae”’ all 
the new species of these »adumbratiunculae” are mentioned, 
most of them under the same latin names, some under 
other latin names, and are described in Dutch. The names 
in the »adumbratiunculae’” are thus preoccupied by the 
names in the catalogue. These latter names however cannot 
be considered, because the author of the names and of the 
descriptions is unknown. 
When the new names of the »adumbratiunculae’’ could 
be considered, i. e. when they had not been preoccupied 
in the catalogue, they yet are to be rejected, as the work 
published in 1764 was that of an anonymus, which, not- 
withstanding the quotations by Linnaeus in 1766 or the 
statement by Pallas himself in 1811, we may not attribute 
to Pallas, when quoting it. It is strange, that Pallas in 
his Zoographia Rosso-Asiatica, is sometimes wrong in the 
quotations of his own work, f.i. he synonymizes Scolopax 
testacea (n° 301 of the »adumbratiunculae”’) with Limosa 
lapponica of Linnaeus, notwithstanding the description of 
Scolopax testacea clearly shows, that this is the curlew- 
sandpiper, Ancylocheilus subarquata (Güldenstädt), which bird
