I have also to acknowledge with gratitude the permission liber- 

 ally granted to me by the Trustees of the British Museum, the 

 Zoological Society, Messrs. Macmillan and Co., and Messrs. Black 

 and Co., of Edinburgh, to publish copies of woodcuts laken from 

 their publications. The work from which the cut is taken is 

 quoted in each case. Several of the illustrations are, by permis- 

 sion of the Zoological Society, taken from drawings by the late 

 Col. Tickell, and from the superb collection made by Mr. B. H. 

 Hodgson, both of which series are now in the Society's Library. 

 The majority of the cuts are copied, from drawings by Mr. E. 

 E. Holding and Mr. P. J. Smit, by the Typographic Etching 

 Company's process.
