Since Mr Bichard Tjäders retnrn to Sweden from 

 his expedition to British East Africa 1906 he kindly presented 

 to the Swedish Natural History Museum some mammals 

 and birds, and among the former were found two Antelopes, 

 a Dik-dik and a Waterbuck, which appear to be new and 

 therefore are described in the following paper. 



Madoqua [Rhynchotragfus] nasoguttatus n. sp. 



When Oldfield Thomas in Proc. Zool. Soc. 1894 on 323 

 and following pages gave a review of the species of »Dwarf 

 Antelopes of the genus Madoqua» known at that time he 

 pointed out that the different species could be divided into 

 two natural groups. The first of these was characterized by 

 the following words : »Last lower molar without a third lobe; 

 upper line of premaxillee slanting, scarcely curved. Proboscis 

 less developed». The second group again was distinguished 

 by the following characteristics : »Last lower molar with a 

 third lobe; upper line of premaxillse S-sbaped. Proboscis more 

 developed».
