dish C. PICTURATUS 



n. s. 



The diagnosis of the new species will be then: 



Cercopitiiegus picturatus, n. s. mihi. — Head, nape and back dark 

 yellow mixed, each hair showing yellow rings. A black frontal band. 

 Round lhe eyes a broad blue ring eye glass shaped. A white cordi- 

 form nasal stain with the point turned downwards. Black whiskers. 

 Near the back part of the whiskers pale yellow, and from here as far 

 as lhe ears bluish yellow white. Temples light sky blue. Ears blue in 

 the fore part, and flesh coloured behind, with light brown strong stiff 

 hairs. Small moustache bluish white; lips white. Chin and the whole 

 of the inferior jaw dirty white. Throat white, somewhat bluish, chiefly 

 on the upper side. Breast, belly, legs and inner part of the thighs 

 gray. The iriside of arms deep grey. Tail brown red over and under, 

 except on the underside of the basis, when it has the same colour as 

 the belly. Bluish scroton. 



Rubbing the hand against the hair in ali parts of the body a blue 

 colour is observed, which seems to predominate ali over the skin, 

 and which appears through in the white and greyish regions of lhe 

 animal. 



Habitat west of Africa. 



The variety of colours adorning this species serves as a reason for 

 the designation by me proposed of — picturatus. 



The animal, upon which the anterior description has been based 

 is a male adult, nearly 14 years, which was sent to Europe 10 years 

 ago, and living now (july 1886) in the Zoological Garden of Lisbon, 

 whitber it was removed together with ali the others animais of the 

 small Menagerie of the National Zoological Museum.
