to have been inserted in its proper place, although there 

 may of course have been errors in the determination of the 

 species. 



For several years it has been my practice to bring before 

 the scientific meetings of the Society short notices of the more 

 important accessions to the Menagerie, with the object of call- 

 ing attention to such as are of special interest. These notices 

 are subsequently printed and published in the ' Proceedings ' 

 of the Scientific Meetings. Both our ' Proceedings ' and 

 ( Transactions ' also contain frequent communications re- 

 ferring to specimens living, or that have previously lived, in 

 the Society's Gardens. I have thought that it would add 

 to the value of the present Catalogue to add references to 

 the ' Proceedings ' and ( Transactions ' in all these cases, so 

 as to make the Catalogue a sort of index to numerous pas- 

 sages in our scientific publications that refer to specimens in 

 the Society's collection. 



When animals have been figured in our publications from 

 specimens in the Gardens a reference to the figure is likewise 

 added. 



The thirty woodcuts in the present Catalogue have mostly 

 already appeared in the Society's ' Proceedings.' Some of 

 them, however, have been kindly lent to me for the purpose 

 of this Catalogue by the proprietors of ' Nature.'
