This list of exceptions to the generic names 

 wMch Dr. Trouessart has adopted should not be 

 considered as a reflection on the value of his 

 work. Its main object is to illustrate the 

 author's metbod of selecting names and to call 

 attention to some of tbe earliest ones which do 

 not bappen to be now in common use. It bas 

 been prepared to increase, if possible, tbe useful- 

 ness of tbe work ratber tban to detract from it. 



So far as species are concerned the catalogue 

 is evidently mucb more complète, altbougb, as 

 pointed out above, there are a few omissions. 

 There is, of course, room for diversity of 

 opinion concerning the validity of some of the 

 species which are given récognition, but no one 

 can be personally familiar with the characters, 

 history and synonomy of sucb a multitude of 

 forms, and ail that the autbor could do was to 

 take the latest revision of eacb group as bis 

 guide. In adopting this course he bas done 

 ail tbat could be expected and bas produced a 

 valuable résumé of the labors of specialists in 

 many groups. 



In fact, too much can bardly be said in favor 

 of tbe catalogue. It represents'an enormous 

 amount of painstaking labor and will long re- 

 main a monument to tbe industry, patience and 

 bibliographical skill of its autbor. It is indis- 

 pensable to the student of mammals and its 

 chief drawback is, perhaps, its high price (66 

 Marks), which may put the book beyond the 

 reach of some who need it most.
