Pakts I. and II. of this series, supplementing my paper 

 published in tiie Proe. Zool. Soc. for 1910, a])peared in the 

 Ann. & Mag. Nat. Hist, for June and August of this year. 

 As iu those papers, the refereiu;e numbers inserted after the 

 genera and species in the following pages apply to the 

 treatise issued in 1910. 



Subfamily Bvbalinm. 

 Genus Damaliscus^ Scl. & Thos. 



In ]910 I described the preorbital and pedal glands of 

 this genus from dried skins of 1). korriyum. I am now able 

 to supplement that account from fresh material of two 

 South African species, T). albifrons and D. jnjyaryus. 



Damaliscus albifrons, Burcb. 



The muzzle (fig. 1, A, B, C) is long, broad, and depressed, 

 Avith mobile upper lip and fleshy, valvular, narrow, and 

 elongate nostrils, lined for some distance inside, both above 

 and below, with hair. The rhinariuni is much reduced, but 

 is broad between the narrowed inner ends of the nostrils ; 

 beneath the septum it is continued down the upper lip as 

 a short mesially grooved philtrum, which rapidly narrows 

 from its wide base to its pointed lower end which reaches 

 the inferior edge of the upper lip. Dorsally it extends as 

 a moist baud along the upper lid of the nostril, but falls 

 short of the posterior angle of the nostril by some distance; 

 on the lower lid of the nostril there is no rhinarial extension
