tence of type specimens and the place where they are deposited should be known, especially in cases where only very few or no more specimens have been since collected, I propose 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 specimens 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.
