narrow white line rounds the hoofs. The tail is proxi- 

 mally colored like the back ; distally it is almost black, and 

 so is the tuft; below it is white. Its length without the tuft 

 is about 32 cm. The length of the ears is about 22 cm. 



" The horns appear to be rather short and stout and 

 less curved when compared with a typical defassa. Their 

 length along the anterior curvature is about 48 cm. and

" Basal length of skull 374 mm. 



Length of nasals 165 " 



Distance from gnathion to orbit 253 " 



Length of upper molar series 99 "

I may mention in this connection that I was fortunate 

 enough to bring home at least two other new species of 

 East African mammals, one being a small dwarf antelope, 

 or dik-dik, the other a different species of bush buck, which 

 latter has gone to the American Museum of Natural His- 

 tory in New York and received the name '* Tragelaphus 

 tjaderi." 



The impala, often also called " Pala " and " Impalla," 

 is one of the most graceful of antelopes. A full-grown 

 impala stands only from three feet to three feet three 

 inches high, but appears to be much larger, as the animal

 The horns of young males form a perfect lyre, but as the
