The above-given measurements were taken in the flesh. 



Cercojnthecus pygerythrus with its subspecies, as here recog- 

 nised, ranges from Uganda to Cape Colony. Broadly speaking, 

 East-African examples differ from South-African examples in 

 being yellower in colour and in the marked evanescence of the 

 black speckles from the hair on the sides of the body, which are 

 thus more uniformly tinted yellow, sometimes with a tinge of 

 red. South-African examples are, as a rule at all events, more 

 uniformly speckled all over and much greyer in colour. I have 

 selected for descriptioii as subspecies some examples in the British 

 Museum which seem to represent distinguishable local races.

To this subspecies I refer a young male specimen in the British 

 Museum from Angoniland, Brit. Centr. Africa [Sir A. Sharpe, 

 0.11.19.1). The coat is long and yellowish green, speckled with 

 black on the head and dorsal area of the body. The sides of the 

 body are strongly tinged with pale rusty red, a tint which is 

 strongly in evidence when the hair is parted to show the under-fur. 

 The whiskers are short, greyish ticked with black. The end of 

 the tail is black, but the hands and the feet are scai'cely 

 darker than the rest of the limbs. This is possibly due to the 

 immaturity of the specimen. The hairs round the sp^'otum are 

 red. 



The red tinge of the hairs on the sides of the body and round 

 the scrotum distinguish this form from the typical S. -African 

 C p. pygerythrus. 



The exact locality of the type of C. rufoviridis was unknown, 

 but since Matschie declares that this Monkey was redescribed as 

 C . Jiavidits by Peters, I regard the Mozambique form as typical of 

 C. p. rufoviridis.
