328 ON THE DWABF ANTELOPES OF THE GENUS MADOQUA. [Apr. 3, 



Dimensions of the type, an adult male in spirit i — Head and 

 body 470 mm., hind foot to base of hoof 159, ear from notch 59. 

 For skull-nipasurements see table, p. 320. 



Bab. Northern half of Somaliland. 



This, the ordinary " Dik-Dik " of Northern Somaliland, seems 

 to be very common throughout its range. Capt. Swayne tells me 

 that during every day's march they are constantly being put up 

 and shot, exactly like the common European hare, the habits of 

 which they closely imitate. 



Although undoubtedly very closely allied to the Abyssinian 

 species, its differences, both in size and colour, appear to be so 

 marked and so constant that I no longer feel justified in assigning 

 it to that form. The name of M. saltiana should therefore be 

 entirely struck out of the list of the Somali fauna. 



Lastly we have to deal with a species which, found, like 

 M. phillipsi, near Berbera, is there well-known as distinct both to 

 sportsmen and natives, and has a different local name. I propose 

 to name it after the enthusiastic naturalist and sportsman who first 

 drew my attention to its distinctness, and whose notes on it have 

 been already published in the ' Proceedings.' 



Madoqua swatnei, sp. n. 



Colour approximately as in M. saltiana ; size less than in M. 

 phillipsi, and therefore far less than in M. saltiana. Colour of 

 back grey with a strong fulvous suffusion (" isabella " of Ridg wax- 

 seems the nearest, but is not yellowish enough). Limbs rufous, 

 and sides faintly so, but very different from the strong well-defined 

 rufous of M. phillipsi. 



Of this species the Museum has three skins, brought home by 

 Capt. Swayne from Berbera, and of these No. 94.2.21.15 is 

 selected as the type. 



The measurements are as follows : — Head and body (c.) 500 mm., 

 hind foot without hoofs 149, length of hoof 22. 



Besides the skins, one skull of Capt. Swayne' s (94.2.21.20) and 

 another one (85.11.16.3), collected at Gerbatir, N. Somali, by Herr 

 Menges, are referred provisionally to this species, and the measure- 

 ments of the former given in the table on p. 326. 



Capt. Swayne tells me that the native name of M. swaynei is 

 " Guyu," of M. phillipsi " Gol-ass,'' and of M. guentheri " Gussuli." 



The following rough synopsis of the species of Madoqua will 

 help to summarize the results arrived at : — 



A. Last lower molar without a third lobe ; upper line of pretuaxillae slanting, 

 scarcely curved. Proboscis less developed. 

 a. Back yellowish or fulvous grey, sides scarcely more rufous. 

 a 1 . Size larger, basal length of skull 95 inm . Abyssinia. 



1. M. saltiana, Ulainv. 

 b 2 . Size smaller, basal length of skull about 78 mm. N. Somali. 



2. M. swaynei, Thos.
