 variegation ; in some, rufous on the breast, and 

 white beneath. 



The two genera of Simla and Lemur may be 

 said to constitute the real or proper Primates : 

 Linnasus, however, as is well known, places in this 

 order the genus Vespertilio or Bat j an association 

 which at first appears incongruous, but which is

 the structure of those animals ; though not appa-

 genus Lemur to Vespertilio appear too abrupt, if we 

 consider, that in the Linnaean genus LEMUR once 

 stood a very curious animal, allied in many points 

 to the rest of that tribe, but so different in others, 

 that it is now, by the common consent of Zoolo- 

 gists, removed from it, and allowed to constitute 

 a distinct genus. It is the Colngo, formerly called

 length, or from head to the extremity of the tail, 

 and is furnished with expanded lateral membranes,
