which are the typical long prehensile tailed representa- 

 tives of the family Cebidae and the variety commonly 

 seen in the menageries. The non-prehensile tailed mem- 

 bers of this family are the Owl-faced Monkeys of the 

 genus Nycthitithecus, the Squirrel Monkey of the genus 

 Chrysothrix, the Brazilian Titi Monkey of the genus Cal- 

 lithrix, the Saki Monkey of the genus Pithecia, the Ukari 

 Monkey of the genus Uacaria, and the Howling Monkeys 

 of the genus Mycetes. 



THE LEMURS. 



The Lemurs, according to Linnaeus, comprehend all the 

 Primates that have in either jaw incisors different in num- 

 ber from four, or at least differently directed than those 

 of the Monkeys; this negative characterization could not 

 fail to embrace very different beings, while it did not even 

 include those which should be combined. Geoffrey has 

 established several divisions of this genus which are much 

 better characterized. The . fore-thumbs of these animals 

 are well developed and opposable, and the first hind finger 

 is armed with a pointed raised nail, all the other nails 

 being flat. Their fur is wooly, and their teeth exhibit 

 sharp tubercles catching in each other as in the Insectivora. 

 They are very active animals, and from their pointed 

 heads have sometimes been called Fox-nosed Monkeys. 

 Their food is fruit. Their species are very numerous, but 

 they are only met with in the Island of Madagascar where 

 no Monkeys are found. Nearly all the difference that 

 exists between the different species of Lemurs is in the 

 color. Their skins are of little value. 



The Black Lemur (Lemur-macaco) is a handsome ani- 

 mal about twenty inches long, which inhabits the dense 

 inland forests on the Island of Madagascar. The head 

 and back are covered with a thick jet black fur about 

 one inch long, but on the chest the thin fur is brown with 

 a patch of white in the center. 



The Black and White, or Ruffled Lemur (Lemur-albi- 

 frons), is really a variety of the Black Lemur and is found 

 in the same habitat. It has the same narrow head, short 

 tail, long legs, and fingers furnished with spongy pads. 

 The back and lower half of the body are light brown, 

 almost white, but the hind legs and arms are a dark 

 brown.
