(hilai-. On the fore feet no such fringes exist, the false 

 hoofs being- small, close together, and overlapping^. 



Strepsiceros imberhiSy Blyth. 



Of this species I have seen one fresh specimen, an imma- 

 ture castrated male from Somaliland, and the feet and 

 inguinal area of an a;lult female from British l^^ast Africa, 

 kindly brought home for me by Mr. F. C. Selous. 



Tliese specimens reseiuhie in nearly every particular tlie 

 example of S. strepsiceros, above described. Theupperside of 

 tiie rhinarmm, however, was not overgrown wiili hair to quite 

 tlie same extent, and tiiere was a single pair of inguinal 

 glamls, eacli consisting of a narrow sack 2 inches deep, with 

 a small circular oriliee, and lying far out in advance of the 

 two pairs of mamnue, as in 'fnujelnplius and Llmnotrajus. 



The (jkinds close to the false hoofs (fig. 3, D) of the hind 

 feet were exactly as described in (S. strepsiceros, and on the 

 fore feet the false hoofs were smaller than on the liijid feet 

 and separated by a narrow stri[) of naked skin, horny i.i 

 one ol the specimens. 



The penis of the castrated male was very small and simple, 

 Avitii a bluntly rounded termination. Tlie urethral canal 

 Mas not prinluced beyond the end of the glans. 



Strepsiceros has hitherto been distinguished from Trucje- 

 laphus merely by small differences in the horns of very little 

 systematic value. Particularly satisfactory, therefore, is the 

 (iiscovery of the ditterence between the two genera supplied 

 by the glands adjoining the posterior i'alse hoofs. 



Genus 1 aurotuagus, Wagu. 

 Taurutragus oryx, Pall. (p. 932). 



To the description of the cutaneous glands of this species 

 ])ublishcd in 1910 1 have to make one important addition. 

 This is the presence of glands close to the false hoofs of the 

 hind legs, precisely resembling those described above under 

 Strepsiceros. These are as well developed in a calf one day 

 old as in the adult, and they are the ouly specialized cuta- 

 neous glaiuls present in the genus, so far as my observations 

 go (tig. 3, A, C). 1 have never succeeded in finding a trace 

 of the preurbitul ijland described by Mi". W. L. Sclater, 

 and am compelled to disbelieve in its existence. 



The rhifiarium (Hg. 3, A, B, C) in the adult is not " bovine,^' 



* Nyala antjdsi resembles Strepsiceros and differs from Trai/elaphus iu 

 possessing- the glaudular fringes by the false hoofs of the hind legs.
