PREFACE. 
This Guide has been prepared with the object of being of 
service not only to those who endeavour to learn something from 
a cursory view of the collections on a single visit to the Museum, 
but also to those who desire, by closer study, to acquaint them- 
selves with the general arrangement and principal features of 
the members of the class of animals of which it treats. As the 
Great Game Mammals (Ungulata) form the subject of a special 
Guide, they are treated briefly in the present work. As was 
tlie case with tlie 8th edition, the present Guide has been 
revised and brought up to date l)y Mr. R. Lydekker, F.R.S. 
SIDNEY F. HARMER, 
Keeper of Zoology.
