APPENDIX IlI.—MAMMALS 473 



Gazella spekei (Blyth). Speke's Gazelle. 

 (Somali name, " Dhero.") 

 This gazelle, which was described by Blyth in 1856, inhabits the high- 

 lands, while Gazella pelzelni is a lowland species. Apart from other 

 differences, the sportsman is at once struck by the exaggerated folds and 

 ridges on the nose of this species as opposed to the ordinary smooth skin 

 on the nose of G. pelzelni.

Gazella sa^finnerringi (Cretzschm.). Soemmerring's (jazelle. 

 (Somali name, " Aul.") 

 This species of gazelle was another of the discoveries of the indefatig- 

 able traveller Riippell, who sent specimens to Frankfort, where Cretzschniar 

 described it in 1826. 



The North Somali form, Gazella sa'intnerri/igi berberana oi Matschie, is 

 larger, and darker, with differently curved horns. 



LitJiocraniiis ivalleri sclateri (O. Neumann). Sclater's Gerenuk. 

 (Somali name, " Gerenuk.") 



Herr Oscar Neumann first pointed out in 1899 that the Somaliland 

 and Abyssinian gerenuk is somewhat different to the East African or 

 Waller's gerenuk. The northern form is larger, has much finer horns, a 

 longer neck, is less rufous in colour, and has not got the black knee-tufts ; 

 the white markings of the tail are also different. Sclater's gerenuk has 

 been treated as a distinct species both by its describer and Messrs. Sclater 

 and Thomas, but I feel sure it is more reasonable to treat it only as a 

 northern race or sub-species, and have therefore recorded it trinomially.
