Oarehia Goslingi, sp. u. 



An Ourebia of the size of hastata, Peters, from Nyasa, 

 larger than kenijiv, Meiiiertzh., of British East Africa, and 

 with longer horns than montana, (Jretzschm., from the Soudan, 

 with a striking black j)atch on the forehead between the horns, 

 extending on to the base of the ears. 



Colour-pattern and colouring as in other members of the 

 genus, but there is a distinct darkening of the back (even 

 blackish in the type specimen), and a well-marked black 

 patch on the foreliead between the horns, extending on to the 

 bases of the ears, curiously recalling the somewjiat similar 

 marking in the very distinct 0. oribi of S. Africa. 



Skull only equalled in size by that of hastata ; distinguished 

 by a marked and characteristic convexity of the rostrum, 

 commencing in front of the frontal depression, and extending 

 to the unusually depressed tips of the nasals. Horns longer 

 than in montana, but shorter and slighter than in kenyce. 



Dimensions of the type : — 



Head and body 940 mm.; tail 94; hind foot 300; 

 ear 107. 



Skull: greatest length 182; basilar length 160; greatest 

 width 73; length of rostrum in front of orbit 98; length of 

 nasals 65 ; length of frontals 56 ; interorbital breadth 44 • 

 bulla} 20. 



Hab. Niangara, Upper Welle Basin. 



Type. Adult female. Original number 125. Collected 

 by Capt. G. B. Gosling on 9th June, 1906. (Examined two 

 complete specimens and one head-skin and skull.) 



The frontal black patch i^f this species is a very distinctive 

 character, and is equally distinct in all three of the specimens 

 examined. In the Katural History Museum collection there 

 is a specimen oi montana ('?) from tlie White Nile which has 

 a distinct dark brown patch on the vertex; this, however 

 does not extend on to the bases of the ears; in no other form 

 is a black patch like that of the present species to be found 

 except in the Soutli African 0. oribi, a species geographi- 

 cally barred from any close affinity. The larger skull 

 differentiates 0. Goslingi from either montana or kenyce^ 

 and from hastata it is separated as well by its geographical 

 position as by the peculiar profile of its skull and its black 

 frontal patch.
