132 Mr. M. A. C. Hinton on the Klipspringers of 



General colour of upper parts as in actratos, but noticeably 

 lighter. No white patches on face, the preorhital region 

 and top of the muzzle being light buff. No black evident 

 upotj the forehead. Ears much lighter, pale ociiraceous at 

 the base ; outer half of the proectote white ; dark ground 

 of tlie remainder of the ectote almost hidden by the buff 

 '' lining " hairs, only its margin appearing dusky ; entote 

 cream. Dorsal surfaces of fore limbs pale buff, becoming 

 greyish over the cannon-bone; of hind limbs light grey. 

 No dark patclies above tiie lioofs, the regions normally 

 occupied by these patches lighter and clearer than elsewhere. 



Skull normal ; female without horns. 



Ti/pe. An adult male. B.M. no. 20. 12. 8. 2. Collected 

 at Esquimina, south of Benguela, on the coast of Angola, 

 and presented to the Museum by Mr. F. Tyler Thompson. 



Hab. Coastal district of Angola. 



Tiie subspecies is very clearly distinguished from the 

 related forms by its pale colour, the characters of the face 

 and ears, and by the absence of dark patches above the hoofs. 

 I have much pleasure in naming it after Mr. F. Tyler 

 Thompson, wlio is well known to all sportsmen and others 

 familiar with Angola. 



In 1911, Lydekker called attention to the presence of 

 Klipspringers in Northern Nigeria ; and on the basis of a 

 skull received from Dr. Porteous and stated to have come 

 from the Duchi 'n-Wai Range, in the province of Zaria, he 

 described a new subspecies, " 0. saltaior portevsi " (P. Z. S. 

 1911, 2, p. 960). In the 'Catalogue of Ungulates' the 

 name is corrected, and appears as 0. oreotragus porteousL 

 The external characters of this form are unknown. 



In 1913, Mr. Hyatt presented the skin and skull of a male 

 collected by him at Leri 'n-Duchi, N.E. Zaria Province; and 

 in the following year the Museum received from the same 

 donor the skin of a female collected at a point 50 miles E. of 

 Zaria. The male is in somewhat faded pelage, but making 

 due allowance for this, there is such close agreement between 

 the two skins that there can be no doubt that both belong to 

 one and the same subspecies. On comparing the skull of 

 the male with the type and only specimen of j)orteousif such 

 marked differences are seen that I do not think it possible to 

 identify Mr. Hyatt's specimens with the form described by 

 Lydekker. The latter must, in my opinion, have come either 

 from some other part of the Duchi 'n-Wai Range, or, what is 

 more probable (having regard to the fact that " Yola," 

 instead of " Zaria," was named in the original description).
