PEEFACE. 



It is no small satisfaction to be able to announce the completion 

 of the fifth and final part of this Catalogue, of which the first was 

 published less than three years since. 



Of its utility to the student of Mammalogy there can be no 

 question. If it contained a bare list of specimens with their 

 localities and references to the works in which they are described, 

 it would be of much value ; but when, as is often the case, both 

 distinctive characters and descriptions are given in addition, it 

 becomes a still more important work of reference, which must be 

 indispensable in every Biological library. 



The €ollection, under the excellent skill of Mr. William Davies, 

 assisted by Mr. Arthur Smith "Woodward, has been revised, arranged, 

 and named, so as to correspond in order, as nearly as the exigencies 

 of exhibition-space will permit, with the several suborders and 

 families proposed in this Catalogue, references being everywhere 

 affixed to figured and described specimens. 



To these Assistants and to Mr. Lydekker my best thanks are 

 due for the admirable manner in which they have cooperated to 

 complete the cataloguing and arrangement of this important section 

 of the Palseontological Collection.
