To the east oî C. a. cirrhorhinns may again live another race 

 of ascanius, because a spécimen (c?, n" 1794) collecLeù by 

 PiLETTE 29-IX-igi9 at Lake Alber Edward lias a nasal spot 

 which resembles that oi kassniciis, and on the same there can also 

 be traced a black brow-band especiallv on the sides. On the other 

 hand the lower cheek-band is verv faint and onlv represented bv 

 black tips to the somewhat yellowish white hairs of the whiskers, 

 but, unlike in Schmidti, this band may be followed ail way to the 

 snout, where it also widens, although in the same indefinite manner. 

 The tail is, of course, white below in its basai portion. 



It mav also be mentioned hère, that D' Bayer has presented to 

 the Congo Muséum a female spécimen (n° 2169) from British 

 East Africa signed, « Zuwani river, Campi Simba », which proves 

 to be a Cercopithecus ascanms with a white nasal spot, a verv 

 broad jet black broAV-band and a well pronounced, black lower 

 cheek-stripe, which runs forwards to, and up along the sides of the 

 white nasal spot. This cheek-stripe is not so broad as in typical 

 ascanius, and it is not widened at the sides of the nasal spot in anv 

 verv perceptible degree. On the other hand it meets the black 

 interorbital stripe which is verv well developed in this form and 

 broadens at the nasal spot, the upper margin of which it covers 

 along its whole length in a verv characteristic manner. The cheek- 

 patch is greyish white (not showing anv yellow shade). The rings 

 of the hairs on the head are « honey vellow » (Oberthur : 35), 

 those of the back something between « fawn » (308.2) and 

 « tan » (31 7.1 and 317.2). By this the gênerai appearance is rather 

 dark rufous. The upper arms and thighs are speckled like the back. 

 Otherwise the fore limbs are black, and the hind limbs dark grey, 

 darker than f. i. in ascanius spécimens from Lake Leopold IT The 

 lower side is quite white. The tail is unfortunately missing. 



Altough the spécimen thus is somewhat incomplète, I think 

 that the very distant habitat together with the characteristics 

 mentioned may give sufïicient reason for recognising it as a repré- 

 sentative of a separate race, Cercopithecus ascanius orien- 

 talis, an eastern offshoot of this otherwise western species. 



D' Bayer has kindly informed me, that « Campi Simba » was the
