QUADRUMANA. 59 



American monkeys, they have the head round; visage flat; nostrils lateral; 

 no cheek-pouches, and, like the Sakis in particular, the tail not prehensile. 

 They have only, however, twenty grinders, like the monkeys of the east- 

 ern continent; all their nails are compressed and pointed, those of the hind 

 thumbs excepted, while their anterior ones are so slightly separated from 

 the fingers, that it is with hesitation we assign to them the name of quad- 

 rumana. They are pretty little creatures, of agreeable forms, and easily 

 tamed. 



M. GeofFroy distinguishes the Ouistltis, properly so called, which he 

 names Jaccuus and whose peculiar characters are pointed inferior incisors, 

 arranged on a curved line, equal to the canines. Their tail is annulated 

 and well covered with hairs; the ears generally ornamented with a tuft. 



Sim. jacchus, Lin.; in Paraguay the Titi. (The Common Ouistiti.) Tail 

 tolerably well tufted, coloured in rings of brown and white; body greyish- 

 brown; two large tufts of white hairs before the ears. From nearly every 

 part of South America. 



Lemur, Lin. 

 The Lemurs, according to Linnaeus, comprehend all the Quadrumana which 

 have in either jaw incisors differing in number from four, or at least diffe- 

 rently directed from those of the Monkeys. This negative character 

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

 unite those which should be combined. Geoffroy has established several 

 divisions in this genus which are much better characterized. The four 

 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 are flat. 

 Their fur is woolly; and their teeth begin to exhibit sharp tubercles catch- 

 ing in each other as in the Insectivora. 



Lemur. — Maris, properly so called. 

 Six incisors in the lower jaw compressed and slanting forwards, four in 

 the upper that are straight, the intermediate ones being separated from 

 each other; trenchant canines; six molares on each side above, six below; 

 ears small. They are very active animals, which, from their pointed heads, 

 have been called Fox-nosed Monkeys. Their food is fruit. Their species are 

 very numerous, and are only met with in the island of Madagascar, where 

 they appear to replace the Monkeys, none of which it is said are tobefound 

 there. Nearly all the difference that exists between them is in the colour. 



IkDBIS. — LlCHANOTUS, lUig. 



Teeth like the preceding, except that there are only four below. 



One species only is known; it has no tail; is three feet high; black; face 

 grey; the Lemur Indri of Sonnerat, Voy. I, pi. 86. The inhabitants of 

 Madagascar tame and train it like a dog for the chase.
