The lemurs or spectre-animals, makis (a small family of which 

 m.ore than 30 species are now known), belong chiefly to Madagascar 

 as their home ; a few species live on the continent of Africa, others 

 in the warm regions of Asia and in the Indian Archipelago. These 

 animals are distinguished from the monkeys and further removed 

 from man by the two-horned uterus, by the lower jaw remaining 

 permanently divided in the middle, and by the orbits open behind 

 and not separated from the temporal fossae by the great alse of the 

 sphenoid bone. There is, however, a bony ring separating the orbits 

 from the temporal fossae, and formed by the junction of a process 

 of the frontal with the malar bone, a disposition not present in 

 Galeopithecus. Linn^us united the species known to him with 

 Galeopitliecus in his genus Lemur.

 fur woolly, chief colour brown, with a more ruddy tint over the legs and 

 on the tail, the belly grey ; in the eastern parts of Madagascar. By its 

 long tail it is distinguished from the preceding, which is very different in 

 habitus; on it is founded the genus Hahrocebus Wagn.
