PREFACE. 



The prefatory remarks in the preceding volume explain the 

 purport of the " Hand-book " of the Primates, which has 

 been undertaken by Dr. Forbes. I hope that the portion of 

 the work devoted to the geographical distribution of these 

 animals will be found to be of some interest; but, as ex- 

 plained by the author, the meagreness of the material in 

 Museums renders the definition of the exact habitats of Mon- 

 keys extremely difficult.
