External Characters of Ruminant Artiodactyla. 221 



far forwards between the nostrils, more than halfway along 

 their length, forming a field with an evenly convex antero- 

 lateral border. From the front the upper edge has a sinuous 

 curvature, and the depth of the rhinarium down the middle 

 line is about equal to the width of the intern arial septum ; 

 the inferior edge is slightly angled, but is not continued as 

 a philtrum down the upper lip, which is continuously hairy 

 across the middle line *. 



Preorbital and inguinal glands are absent, as Owen and 

 Ogilby correctly recorded, 



The pedal glands on all four feet consist of dilated hair- 

 lined pouches, opening by a narrow passage and a small 

 orifice on the front of the pastern just above the summit of 

 the folded interlingual web. Tliey resemble those of 0. beisa 

 described in 1910, except that the orifice is small and sub- 

 circular (cf. infra). 



Oryx beisa, llupp. (p. 907). 



I am indebted to the late Mr. F. C. Selous for the fore 

 and hind foot of an adult example of this species from 

 British East Africa. In these the glands were moderately 

 large and saccular, with a narrow cylindrical exit passage 

 and circular orifice. In 1910 I described the orifice of the 

 gland observed on the dried feet of an immature specimen 

 as consisting of an elongated slit. The shape assumed by 

 the orifice in this case was probably due to shrinkage of the 

 skin when drying. At all events, the glands of the specimen 

 brought for me by Mr. Selous resembled those of the fresh 

 specimen of 0. gazella described above. 



Genus ^Egoryx, nov. 



Differs from Oryx in possessing a preorbital gland, a 

 more reduced rhinarium, and curved horns. 

 Type, JEgoryx alyazel, Oken. 



JEgoryx alyazel, Oken (p. 909). 



In 1910 my notes on this species were restricted to the 

 statement that an example living in the Gardens showed 

 the presence of preorbital glands by patches of secretion on 

 the face about one inch in front of the eye, thus disproving 

 the assertions of Owen and Ogilby that the preorbital gland 

 is absent. 



* In the figures illustrating the muzzle of the antelopes described in 

 this paper, no attempt has been made to indicate by shading the trans- 

 verse and vertical convexity of the rhinaria, which thus appear to be 

 too flat.
