Taurotragus and tlieir presence in Tragdaphus and, as is alleged, 

 in Streps'iceros are quite in accordance with the view that Boo- 

 cercus and Tanrotragns are more nearly allied to one another 

 than either is to Strepsiceros or Tragelaphus, a view supported by 

 the terminally tufted tail and the presence of horns in the female 

 in the two former genera. 



Genus Taurotragus Wagn. 



Taurotragus oryx Pall. (Tlie Eland.) 



(Text-fig. 122, A, B, p. 929.) 



This species, according to Owen, who quotes it as oreas and 

 canna, has neither preorbital nor inguinal pits. W. L. Sclater, 

 however, says that the preorbital gland is small, " with a very 

 small circular o[)ening in fiont of the eye in a narrow bare tri- 

 angular space." In two young male examples examined by me, 

 I could find no trace of preorbital gland or of inguinal or pedal 

 glands. The pedal glands wei-e also entirely absent on a foot of 

 an adult kindly supplied to me by Messrs. Rowland Wai-d, Ltd. 



The feet are constructed as in the genus Bos, the entire inter- 

 ungual area being naked, the integument that joins the hoofs 

 together forming a ileep " web" extending forwards from the heels 

 where it is thickest, to the anterior portion of the pastern only a 

 short distance above the proximal margin of the front of the 

 hoof, so that the hoofs are susceptible of but little separation. 



By their glands and other external features the genera of this 

 section may be gi'ouped and contrasted as follows : — 



a. A well-developed preorbital gland opening by a longitudinal 

 valvular slit; horns short, not spirally twisted, present 

 only ill the male (tail not terminally tufted; no inguinal 

 glands). 



b. Preorbital gland relatively large; horn not crested ; a pouch- 



like gland in each false hoof of the hind leg, &c Tetraceros. 



b'. Preorbital gland relatively small ; horns crested basally ; 



skin between posterior false hoofs highly glandular BoselajoJiiis. 



a'. No preorbital gland; horns longish, sjiirally twisteil. 



c. Inguinal glands present ; tail hairy throughout ; no horns 



ill female 'Ti\((/elapfiits, Limnotragus, Strepsiceros. 



c'. No inguinal glands ; tail terminally tufted ; horns present 



ill both sexes Boocercus, Tato-otroiins. 



Subfamily B o v i N ^E. 



Genus Bos Linn. (Text-figs. 123, 124.) 



It is agreed on all hands that preorbital, inguinal, and pedal 

 glands are absent, and that two pairs of niamm:e are present in 

 all the species of Bovinie, whether they be referred to the one 

 genus Bos or the several genera Bos, Bibos, Poephagns, &c. In 

 these respects Cattle are indistinguishable fi-om the large Trage- 

 laphine Autalopes Taurotragus and Boocercus and from the 

 larger forms of Cervicaprinie like Kohus ellipsf/pri/mnus. They 

 also resemble them in the structure of the feet, the interungual
