CHAPTER IX 



DISTRIBUTION OF MONKEYS AND LEMURS 



Section I. — Introductory Remarks 



Having now completed the discussion of the great 

 Zoological Regions of terrestrial and marine mammals 

 and their leading peculiarities, it is proposed to take 

 the subject in another way, and considering the Orders, 

 or great primary groups of mammals, one after the 

 other, to sketch out the mode in which their leading 

 forms are distributed over the surface of the world. 

 We shall then see whether the conclusions thus arrived 

 at appear to lead to similar results to those attained 

 by making geographical divisions our primary subject 

 of study. In doing this it will be more convenient 

 to take the most highly organized groups of mammals 

 first, and to descend gradually to the lowest, revers- 

 ing the arrangement used in the previous chapters of 

 this work. The divisions and names now employed 

 are taken from the last edition of the "List of Ver- 

 tebrated Animals in the Zoological Society's Gardens," 

 (1896), but do not differ materially from those used 

 in Flower and Lydekker's " Mammals Living and Ex- 

 tinct," which we have hitherto mainly followed. These
