trees of any size, although I have known it go into rather 

 dense clumps of jungle. I think, however, on these occasions it 

 sought such retreats as places of refuge and more from necessity 

 than from choice. Both sexes possess horns, those of the females 

 being quite slender and rather straight. The horns of the male 

 are rather stout, deeply ringed almost to the tip, and curved 

 backwards at quite a different angle from those of Pelzeln's 

 gazelle. It is a shy animal, at times quite wild, and one is obliged 

 to take long shots to secure a specimen. As a rule, it seemed 

 as if the males generally led the small bands in the marches about 

 the country they frequented, and I was somewhat surprised at 

 this, for the reverse is generally the case among the deer and 

 antelope. But of course there were instances when I saw the 

 female piloting these bands, the male straggling after her in 

 a very careless sort of way. All the individuals, however, keep 

 a pretty sharp watch, and when anything unusual is seen the 

 whole band stops and regards it intently, for the animals possess 

 a good deal of curiosity and frequently stand and gaze a long 

 time before commencing to run. When first startled they do not 

 go very far, but stop and look back, and if they see nothing will 

 commence to graze again, or play with each other, the males 

 indulging in mock battles or chasing one another with a great 

 burst of speed; for they run with much swiftness. If followed 

 persistently for a time they will leave the locality entirely, at 

 least for a short period. This species soon obtained a fair idea 

 of the range of an ordinary rifle, but was deceived by that of the 

 Lee-Metford and Mannlichers. 



Premaxillae of nearly equal width throughout their length, the 

 posterior end resting on the maxilla, which intervenes and 

 separates them from the nasals, as in Lithocranius. The nasals 

 are flat and broad, and exhibit nothing to indicate the peculiar 

 wrinkled nose of the species. Anteriorly the border is bifurcated, 

 the recesses being quite deep. Lacrymal fossa wide and deep, 

 auditory bullae large and swollen, the paroccipital process, broad 

 at base, compressed laterally, narrowing rapidly at tip, which 

 hangs some little distance from the bulla. External auditory 

 meatus, tubular, large. Palatine, narrow, pointed anteriorly. 

 Premaxilla^ of nearly equal width throughout their length. Horns 

 only slightly curved, annulated for nearly the entire length.
