ORDER QUADRUMANA. 261 



Its total length is from three to ~four feet, the tail is 

 nearly as long as the whole body. 



It was named Entellus by its first describer M. Dufresne, 

 from some fancied resemblance to an athletic old man. 



" Stat gravis Entellus, nisuque immotus eodem : 

 Corpore tela modo atque oculis vigilantibus exit." 



The red monkey, or Patas, is a pretty animal, and as it is 

 well known we shall add nothing to the Baron's description of 

 its person. It is about the size of the last species. Its temper 

 is like that of most of the Guenons, violent, capricious, 

 mischievous, and little susceptible of attachment. Brue gives 

 an interesting description of the curiosity of those animals 

 which exposed them to the view of his companions. They 

 descended from the tops of the trees to the extremity of 

 the branches, earnestly noticing, and apparently much 

 amused by the boats as they passed along the river. They 

 then began to take courage and pelt at the boats with 

 pieces of wood, fyc, thus provoking a most unequal com- 

 bat. When fired upon, they uttered the most frightful 

 cries, and though many fell, the survivors appeared by no 

 means willing to relinquish the contest. They redoubled 

 their efforts, some flung stones at their adversaries, while 

 others collected their own excrements for a similar purpose, 

 and all displayed a determination of spirit, which must 

 avail them much when engaged with opponents to whose 

 powers their own are at all commensurate. 



The two Mangabeys so closely resemble, that they have 

 been treated by English writers hitherto as one species with 

 a variety, under the name of the white eyelid monkey. 

 Many specimens have, however, lately been observed, and 

 the characteristic differences, however trifling, have been 

 found invariable in all the individuals. This fact affords 

 very just presumptive grounds of different species. Accord- 

 ingly, M. G. St. Hilaire has divided them, giving to the 

 collared Mangabey the epithet JEthiopicus, and to the 

 other that of Fuliginosus.
