SOOTY MANGABEY. 



Type locality. None given. E. Geoffroy's type of C. fuliginosus 

 not in Paris Museum. 



Geogr. Distr. Sierra Leone, Liberia, West Africa. 



Genl. Char. Hair on crown short, directed backward ; face and 

 ears naked ; eyelids white. 



Color. Top of head speckled yellow and brownish black; sides 

 of head blackish ; general color of body and limbs sooty or sooty black, 

 nearly black on dorsal region ; lower part of forearms, hands and 

 feet black; under parts ashy or yellowish gray; tail, upper parts 

 blackish, rest sooty ; face of a brownish color ; eyelids white. 



Measurements. Total length, 1,016; tail, 546.10; foot, 215.60. 

 Skull: total length, 119; occipito-nasal length, 96; Hensel, 81; zygo- 

 matic width, 73; intertemporal width, 47; palatal length, 48; breadth 

 of braincase, 63 ; median length of nasals, 19.5 ; length of upper molar 

 series, 34; length of mandible, 74; length of lower molar series, 37. 



The type of E. Geoffroy's species is not to be found in the Paris 

 Museum, the oldest there being one which died in the Menagerie in 

 1821, nine years after the species was described, but no indication 

 given as to whether it was the type or not. The type of C. atys Aude- 

 bert is in the Paris Museum, a perfectly white animal, with no locality 

 save 'Afrique occidentale,' and half the tail gone. It may be C. 

 ^THIOPS, albino, but no accurate determination is possible. Mr. 

 Pocock contends (1. c.) that the name -ethiops cannot be given to a 

 Mangabey because Linnaeus had already employed the name in 1758.
