Kohus Penricei Rothschild. 



In the Notes from the Leyden Museum, Vol. IX, p. 172, 

 I registered under the collections made by Mr. P. J. v. d. 

 Keilen on his expedition to the Cunene-river a skull with 

 horns of an adult male as Kohus ellipsiprymnus ; this was 

 in 1887. As our Kobus-materisd was rather poor, I thought 

 it better to describe this skull not as the type of a new 

 species, although the locality was a quite new one. I at 

 present judge that it once belonged to a specimen of K. 

 Fenricei Rothschild, described in 1895 by this Author in the 

 Novitates zoologicae, Vol. II, p. 52. Hitherto the skull never 

 has been described, so that it may be of some interest to 

 point out now a few peculiarities of it. Of our skull the 

 lower jaws are wanting. 



Horns very strong, rings very prominent; the extremi- 

 ties bent forwards and inwards so that the horns describe
