﻿NOTES ON THE BIRDS DESCRIBED BY PALLAS IN 



THE " ADUMBRATIUNCULA " OF VROEG'S 



CATALOGUE 



By CHARLES W. RICHMOND 



The Catalogue of Adrian Vroeg's collection, which was brought to 

 light by Mr. Sherborn during his work on the Index Animalium, is 

 one of the rarest of ornithological tracts, only one copy being known 

 to exist. Unlike A. A. H. Lichtenstein's Catalogus Rcrum (of which 

 two copies are known), Vroeg's Catalogue appears to have been en- 

 tirely unknown to bibliographers, and Mr. Sherborn has wisely de- 

 cided to place on record the new matter contained in it by offering 

 a careful reprint of the " Adumbratiuncula." This separately-paged 

 portion of the Catalogue contains descriptions of thirty-eight species, 

 thirty-five of which were supposed to be additional to the tenth 

 edition of the Systema Nature?. Although his name does not appear 

 in connection with it, the " Adumbratiuncula " was written by Peter 

 Simon Pallas, as he tells us in his Zoographia Rosso-Asiatica (n, 

 p. 199), a statement long anticipated by Linnaeus in the 1766 edition 

 of the Systema Nature, where "Pallas, adumbr." is quoted in the 

 synonymy of several species. 



In view of the importance of this first effort by Pallas, it seems 

 desirable to follow Mr. Sherborn's reprint with a list of modern 

 determinations of the new names contained in it. An attempt to 

 supply such a list is offered herewith. 1 

 No. 8. Falco epieyanus Pallas. 



This is Falco nisus Linnaeus, 1758. Male adult. 

 Accipiter nisus (Linnaeus). 

 No. 18. Laniits ruficeps Pallas. 



Unquestionably the Woodchat Shrike, Lauius senator 

 Linnaeus, 1758 (L. auriculatus Muller, 1776; L. pome- 

 ranus Sparrman, 1786). L. senator is based on Albin 

 (Nat. Hist. Birds, 11, p. 15, pi. 16), who describes and 

 figures this species from a specimen without locality. 

 Grant (Nov. Zool., ix, p. 464) gives " Germany " as the 

 type locality, but Albin refers only incidentally to a sec- 

 ond individual from Germany. 

 Lanius senator Li.w.kis. 



1 The correct names of the various species are given in heavy type.
