160 THE ZOOLOGIST. 
A Last of the Vertebrated Animals now or lately living in the 
Gardens of the Zoological Society. 7th Edition. Demy 8vo, 
pp. 550, with 48 Illustrations. Printed for the Society, 
and sold at their House in Hanover Square. 1880. 
Tuts so-called “List,” the first edition of which appeared in 
1862, has grown into a very useful book of reference, for it not 
only enumerates all the animals which have been received from 
time to time by the Zoological Society, but also contains an 
index, as it were, to papers in the ‘Transactions’ and 
‘Proceedings’ in which, as regards many of them, important 
information may be found. 
The number of species of each class of Vertebrates included 
in the present edition of the catalogue is stated to be:— 
Mammals, 615; Birds, 1829; Reptiles, 257; Batrachians, 41; 
Fishes, 83; Total, 2325. The greatest additions have been 
made in the first three classes; only two species of Batrachians 
and none of Fishes having been added since the issue of the last 
edition in 1877. 
In one respect only do we find this catalogue defective; it 
does not inform us with any degree of certainty whether any 
specimen of a given species may be found in the Society’s 
Gardens at the present time. We are well aware of the difficulty 
which must arise in attempting to afford information of this 
kind, for an animal which may be living when the catalogue is 
revised for the printer may be dead by the time the volume is 
ready for publication. Nevertheless, in cases where animals 
once in the Gardens are known to be lost to the Society by death 
or exchange, we think it would be desirable to express the fact of 
- their non-existence by the addition of the letters d or e, as the 
case may require, in order that enquirers may judge what are 
their chances of finding a given species: before making a journey 
to the Gardens expressly to see it. It would then be understood 
that all specimens not so marked were believed to be living at 
the date of revision of the catalogue.
