parative dimensions of the snout. Tims they do not approach the typical dorsalis, and 

 therefore it appears better to regard them as subspecies of castaneus.

»Boloko» is the native name of this little Duiker according to Capt. Arrhenius. 



One of the above noted females has no horns, bnt the others are provided with 

 such. The general colour of the back is different in different individnals. In some spe- 

 cimens it may be said that the posterior back is somewhat »in's röthlichgelbe spielend », 

 as Matschie described 1 the type from Chagwa, Uganda. Other specimens are »warm 

 sepia» (Dauthenay, 305,4) thus resembling C. schusteri Matschie. 



Sylvicapra grimmia lutea Dollman? 



Capt. Arrhenius's collection contains only a skull of this kind. This is very much 

 largcr than the skull of the East African Duiker, S. g. hindei as the following measure- 

 ments indicate: 



Total length of skull 181,5 mm.

Condylobasal length 172,5 » 



Greatest breadth 77 »

Length of nasals GG,6 » 



Least interorbital width 47,4 » 



Length of palate 89,5 »

Neumann has named a subspecies from Kavirondo Sylvicapra abyssinica nyansce, 

 but he has only said that it is darker than the typical abyssinica, and not communicated 

 a single skull measurement. It would thus have been impossible to make any comparison 

 between this skull and Neumann's Kavirondo Duiker, if I had not had the pleasure of 

 receiving some information about it from Professor Matschie. He has kindly written 

 that Neumann's Duiker is represented in the Berlin Museum by the posterior portion 

 of the skull. The following measurements of the same, communicated by Matschie, 

 pro ve plainly the difference from the skull of the present collection: »Breite an den 

 Hornzapfen 38 mm.; grösste Breite etwa 66 mm.» 



From Mani, Lower Shari River, E. Schwarz has described 2 a Duiker, named by 

 him 8. g. pallidior. This race is said to be slightly larger than S. g. abyssinica, but the 

 skull of an adult male of this race is according to the another quoted mucli smaller than
