PREFACE TO THE SECOND EDITION. 



THE first edition of this Catalogue having been found of much 

 use for reference, both by those who resort to the Collection 

 for scientific purposes, and by the Society's numerous corre- 

 spondents in foreign parts, the Council have authorized the 

 preparation by Mr. Eraser, under my superintendence, of the 

 present new edition, which gives the names of such animals 

 as were living in the Gardens on the 1st of January last, 

 together with those of the species that have been received 

 since that period up to the end of May last. 



The present Catalogue includes the names of 821 species of 

 Vertebrates namely, 229 Mammals, 468 Birds, 84 Reptiles, 

 and 40 Fishes illustrated by 2080 specimens in all. This, 

 it will be observed, is a considerable increase over the number 

 given in the former Catalogue, in which only 682 species of 

 Vertebrates were enumerated.
