275 



The Red-Fronted Lemur (Lemiir-rubifroiis) ; the Ring-- 

 Tailed Lemur (Lemur-catta), and the Grey or Brown 

 Mouse Lemur (Cherogalens-nutri), are all smaller than 

 the Black and the Ruffled Lemurs, the general color of 

 each being various shades of grey, with the ■ distinctive 

 markings that the different names indicate. 



The Woolly or Dwarf Lemur (^licrocebus-senithir), the 

 smallest of the Lemurs, is of a brown gvey color and only 

 six inches in length. 



Drill (Dog-Faced Monkey). 



We have devoted so much space to the Quadrumana 

 on account of the general interest felt in these animals 

 because of theories advanced by Darwin and other scien- 

 tists in regard to their relationship to man, rather than 

 because of their value as fur-bearing animals.
