'Repertoire^). Underside of fore limbs reddish (dead leaf 

 no. !_, 'Repertoire^), richer in colour towards extremities 

 (dead leaf no. 3, 'Repertoire'). Under surface of hind 

 limbs very similar in colour to posterior part of belly, rather 

 greyer and darker towards the feet. Tail brownish black 

 (reddish black no. 2, ' Repertoire '). 



Dimensions of the type (measured in skin) : — 



Head and body 760 mm. ; tail 650 ; hind foot 150 ; 

 ear 30. 



Skull missing. 



Hab. 90 kilometres west of the south end of Lake Albert 

 Edward. 



Type. Adult male. Original number 96. Collected by 

 R. Grauer. 



The red-coloured back and dark brownish hind-quarters^ 

 together with the black tail and huffy under surface of the 

 body, indicate that this form must be considered quite dis- 

 tinct from C.graueri. From C. foai it is easily distinguished 

 by its bright red back and head, and from C. nigrimanus, 

 Trouessart, by its red hands, dark brown hind-quarters, and 

 black tail. 



It gives me great pleasure to name this handsome species 

 after Dr. D. G. Elliot, whose intimate knowledge of this 

 group of monkeys has been of the greatest service to me in 

 distinguishing these two forms.
