V. — On the Genus Psittacella. By Ernst Hartert. 



(Plate III.) 



In 1891, when writing the 20tli volume of the Catalogue of 

 Birds, Count Salvadori recognized three different species of 

 the genus Psittacella, Schleg., hitherto known only from 

 New Guinea. At present the genus is enlarged by one more 

 species, described quite recently by Mr. Rothschild, and we 

 can, in my opinion, distinguish as a slightly differentiated 

 subspecies Psittacella brehmi jJaUida of A. B. Meyer. A 

 revised ''key^' to the species o£ this genus is therefore 

 necessary, which I give as follows : — 



1 ) Wing more than 100 mm. : 2. 



I Wing less than 100 mm. : 7. 

 p i Breast with crescentic black bars : 3. 

 ' ( Breast without black bars : 5.
