monotony. We have noticed the same action in young Monkeys of other 

 species. 



Riippell observed this species in Kordofan and Darfur, and it is un- 

 doubtedly the Nisnas of Hemprich and Ehrenberg. The term Nisnas, 

 seems a word of general application, in Egypt, to Monkeys ; for the 

 Hamadryas and the Anubis are thus denominated. According to Dr. 

 Riippell, this species is less frequently tamed in Egypt than the Tota 

 (Grivet, Cere, griseo-viridis), with which the Egyptian peasantry confound 

 it under the common name of Abellan. We learn, from the same autho- 

 rity, that its native appellation, in Kordofan, is Nango. 



M. Ehrenberg, in his description of the Nisnas, as it is called by the 

 Arabs of Ethiopia, remarks, that the adult male, when in full health, is 

 furnished with a copious mane. This character has not been observed in 

 the specimens which have fallen under the Author's observation ; probably, 

 by the expression, a copious mane, is only intended that the hair on the 

 neck, or shoulders, is longer than that on the limbs and back ; but that it 

 has a copious mane, truly so called, as we see in the Gelada or the Hama- 

 dryas, must be regarded as very doubtful. 



Representations of the present species, occur on the tombs of the 

 ancient Egyptians ; and Mr. Ogilby considers that it is " unquestionably 

 the Cepus, which ^Elian, on the authority of Pythagoras, describes as an 

 inhabitant of the countries bordering on the Red Sea," as, indeed, the 

 description, remarkable for its accuracy, proves. The Kebos of Aristotle 

 is probably the Gelada of Abyssinia.

DESCRIPTION. Description of a specimen (No. 36, Cat. Mamm. 

 1838), in the Museum of the Zoological Society, London: General 

 contour stout and muscular ; the fur is soft and adpressed ; but on the 

 fore-limbs the hairs become more rigid and shorter ; on the back they 

 measure from two to three inches in length; the canine teeth are re- 

 markably long (nearly three quarters of an inch), slender, and sharp ; the 

 incisors very short and even ; the head is rounded and short ; the ears 

 are very small, nearly rounded, and, for the most part, concealed in the
