X INTRODUCTION. 



much valuable information in regard to individual specimens, but also 

 for verifying each specimen with its description, by which absolute 

 accuracy is secured in this respect. Thanks are also due to Prof. 

 Boyd-Dawkins, of Owens College, for valuable assistance in the 

 determiuation of the remains of Gervus and its allies ; and to Mr. 

 H. B. Medlicott, Superintendent of the Geological Survey of India, 

 to Prof. L. Riitimeyer, of Basle, and to the Council of the Geological 

 Society of London, for the loan of woodcuts illustrating this and the 

 preceding Part. 



Owing to the purchase of certain specimens after the sheets of 

 this Part were in type, and also to the circumstance that others had 

 been displaced during the rearrangement of the Museum, it has been 

 necessary to introduce several Addenda, which render the work more 

 complete, but less symmetrical than I could have wished.
