AUTHOR’S PREFACE 
To the Palseontographical Society of Great Britain for permission 
to reproduce three of the illustrations in Sir Richard Owen’s great 
work, British Fossil Be^ptiles, published in their yearly volumes, 
viz. Figs. 8, 9, 14. 
To Messrs. Bell and Co. for the following cuts from the late 
Dr. Gideon A. Mantell’s works: viz. Figs. 3, 35, 36, 42, 53, 
67, 68, 73. 
To Messrs. A. and C. Black for the following cuts from 
Owen’s Palceontology : viz. Figs. 85, 99, 104. 
Appendix III. contains a list of some of the works of which 
the writer has made use; but it would be impossible within 
reasonable limits to enumerate all the separate papers which have 
necessarily been consulted. 
Models in 'pa'pier mache, about 12 to 20 inches in length, of 
the following have been made under the supervision of the author, 
and may be obtained from Messrs. Rewman (of Rewman Street, 
Oxford Street, W.), viz. Tinoceras, Plesiosaurus, and Megatherium. 
The numbers of the Figs, given are those in the present Edition (1910).
