the Imperial Collection at Vienna. 15 



tence of type specimens and the place where they are depo- 

 sited should be known, especially in cases where only very 

 few or no more specimens have been since collected, I pro- 

 pose to give in the following pages a catalogue of the birds 

 obtained from the Leverian Museum, with such remarks as 

 seem called for respecting them. 



This catalogue is based on specimens still contained in 

 the Vienna Museum, on the inventory of birds received 

 through Herr von Fichtel of the Leverian collection, and 

 on the old MS. catalogue of our ornithological museum. In 

 the inventory it is said that the species obtained from dealers 

 are marked with an asterisk ; but as the whole acquisition is 

 inscribed as from the Leverian Museum, it is probable that 

 the birds marked in this way were bought by dealers at the 

 auction and then purchased by Herr von Fichtel. Besides 

 these, a number of species are contained in a separate inventory 

 as purchased from Herr von Fichtel in the year 1806. As in 

 a few cases it is said expressly in this catalogue that the spe- 

 cimens are from the Museum Leverianum, and as other birds 

 seem with the greatest probability to be from the same source, 

 I have thought it useful, for greater completeness, to include 

 also these species in the present paper. 



To separate, however, the certain from the probable, and 

 with the intention of giving an account as accurate as possible, 

 I have divided this paper into two parts, the first of which 

 treats of birds obtained directly from the Museum Leverianum, 

 the other of those obtained through dealers and purchased 

 from Herr von Fichtel. 



In both lists I have added such synonyms from older works 

 as seemed in some way useful for the determination of the 

 species, especially the descriptions and plates, which were taken 

 from the specimens here enumerated. 



Supplement ii. of Latham's ' General Synopsis ' is not in our library, and 

 that therefore, respecting the species described therein for the first time, 

 I am only able to compare the short descriptions in the ' Index Ornitho- 

 logicus' and the quotations in Shaw's 'General Zoology.' Under these 

 circumstances it is not always possible to say whether specimens in our 

 collection were Latham's types or not.
