PREFACE. 



"XTHLLIAM ELFORD LEACH, the author of this Pamphlet, 

 wrote it when he occupied the position of Keeper of the 

 Zoological Department of the British Museum. Though not 

 positively stated to be the case, it seems evident, from the 

 manner in which the names of the several specimens are arranged 

 in this Catalogue, that it was intended to be cut up and used 

 to label the collection of Mammals and Birds then in the British 

 Museum. This would account in some measure for the rarity 

 of the tract, comparatively few copies probably having been 

 printed, and of these a number destroyed. It is also a question 

 if it was ever actually published in the ordinary sense, for though 

 the printer's name is given at the foot of the title page, no 

 Publisher's is mentioned. Regarding the many new specific names 

 proposed by Leach in this Catalogue, I believe that hardly any are 

 now in use, older ones having, in most cases, been found for the 

 mammals and birds to which they were applied. 



Fifteen new generic names were proposed for Birds, as 



follows : 



lerax = Accipiter, Brisson (1760). 



Triorches = Pandion, Savigny (1801). 



Mecistura. 



Calamophilus = Panurus, Koch (1816). 



Vitiflora = Saxicola, Bechstein (1802). 



Spipola = Anthus, Bechstein (1805). 



Melizophilus. 



Fedoa = CEdicnemus, Temminck (1815). 



Squatarola. 



Pavoncella. 



Macrorhamphus. 



Gallinago. 



Zapornia = Porzana, Vieillot (1816). 



Moris = Sula. 



Utamania = Alca, Linnaeus (1766).
