INTRODUCTION. XXV 



Among others who gave me the benefit of their assistance, I am under obliga- 

 tion to Lieutenant-Colonel H. H. Godwin- Austen for the plate of Bhizomys ery- 

 throgeuys, reproduced from a sketch made by him from the living animal. 



In coticlusion, I must tender my thanks to the Trustees of the Indian Museum 

 for permission to use for the illustration of this work many original drawings in 

 their possession. 



Calcutta; 

 The 21st December 1878.
