cisiii"- in the ninrnin^- from tlirce to four iiours slie would, if allowed, spend 

 tlic rest of tlic d;iy quietly on one of tlie branches." 



In addition to tlic above species we liavc, — 



The Gray Giblion (I'^'iitu'a lenci'.fca). Color, gray; crown, dark; 

 whiskers, and beard, white ; face, black. 



The Siamang (^S'. si/ndacty'ta). Tiiis species has the second and third 

 toes of tlie Iiind foot united by a narrow membrane, the whole length of tiia 

 first phalanx. It is entirely black, tlie eyebrows and cliin somewhat red- 

 dish. It is gregarious, seeming to be organized into com[)anies, which are 

 commanded Ijy captains or leaders. 



All the gibbons are remai-kable for tiio great length of their arms, which 

 are so long that, wlien tiie animal stands erect the hands nearly touch the 

 cartli. This singular conformation seems to adapt these creatures to their 

 situations in a manner that would scarcely be imagined without having 

 been witnessed. They make their home in the tops and iiigh-reaching 

 branches of the trees of the Oriental forests, which Nature appears to have 

 fitted iiir tlieir accommodation. They delight to make long leaps from tree 

 to tree, and to swing themselves on tiie branches. All species of the 

 Simiada> show consideralde excitement at dawn, and also when nigiit begins 

 to wrap the earth in darkness ; but the gibbons are peculiarly alleetcd by 

 this plienomenon, and pay a kind of instinctive worshi[) to the sun, liailing 

 him with loud cries as he rises, and saluting him in the same manner when 

 he sets. Should their singular matin or vesper service be interrupted by 

 any cause, they instantly vanish in the thickest jiart of the forest. 



JIONKEYS OF THE EASTERN CONTINENT. 



Genus CEKC'oriTiiEcrs — True ^Monkeys. jNIuzzles somewhat promi- 

 nent, tails, chcek-pouciies, callosities on the buttocks, tiic last of tiie inferior 

 molars with four tubercles, mark their generic character. The hair is of 

 two kinds, the outer marked with two colors above, blending in such a 

 manner as to produce in some a tinge of green. Tlie species are very 

 numerous, greatly varying in size and color ; lint all are alike in their 

 propensity to mischief, seeming to delight in pillaging gardens, ravaging 

 cultivated fields, and appropriating to their own use whatever of an eatable 

 nature they can lay their hands on. 



Over twenty species are now known, exhibiting considcraldc differences 

 in the length of the fingers. A few of the larger appear to have some of 

 the generic marks of the Baljoon. The following are some of the most 

 interesting of them, all of which are peculiar to Africa: — 



The Diana Monkey (C'crcojjilhccus JJiana). Beautifully variegated;
