PREFACE. 
The following Plates are selected from the series of Drawings- of Ungulated Qua- 
drupeds made by Mr. Waterhouse Hawkins for the Right Honourable the Earl of 
Derby, chiefly from the animals living in his Lordship's Menagerie at Knowsley Hall. 
They have been lithographed by Mr. W. Hawkins, and coloured, or printed in colours, 
under his superintendence. 
The Plates are accompanied by Lord Derby's notes on their habits, and hy a brief 
description of the specimens of the various Genera, chiefly derived from the study of the 
animals at Knowsley, or in the British Museum. 
It was intended that the Antelopes should have appeared by themselves, in the year 
1847, to be followed by the other Famibes ; but they were delayed by circumstances over 
which I had no control ; and the whole series of the Plates now appear at the same 
time.
