niijrifi'oni^. and coronata, of wln'cli a/n/sfshncff*' is, I tliiiik. a sub- 

 species. 



It is, moreover, well known that the group exemplified hy 

 coroiiata diflers from that exemi)lified by dorsalis in the 

 markedly more iipriglit inclination of the liorns. If generic 

 impoi'tance be attached to tliat character, a proceeding desirable 

 on the grounds of the unwieldiness of the genus Cephalophns as 

 at present recognised, the genus ci\\\ l)e split at all events into 

 three genera which may be distinguished ;is follows : — 



a. Jnguiuiil glands absent Gitevei. 



n'. Iiin'uinal glands present, consisting of a jiair of deep pouches, 

 the orifices of which ai'e remote from the mamma!. 

 f>. Horns inclined backwards in the iihme of the face; ears 



short Cephalo/jhiis. 



b', liorns inclined upwards and backwards, forming an obtuse 



angle with the plane of the face; cars long Sj/lvicajjra . 



The type of the genus Ouevei, as selected by Messrs. Sclater 

 and Thomas, is maxirelli, with which cequatoricdis find melanorhens 

 must be associated. The t3qje of Cephalophus is said to be hUtx- 

 cuUHx, a species in which Owen affirms the existence of inguinal 

 glands. As defined above, the genus also contains dorsalis and 

 tiiyrifrons. The type of Sylvicapra is mergens, but grimmi appeal's 

 to be the oldest name given to the species. 



For the characters of Tetraceros, usually referred to the Cepha- 

 lo}>hiii!e. see p. 921. 



Subfamily M A D o Q u I N M. 



Genus JMadoqua Ogilby. 



(Dik-diks.) 



The availalde ('\i(U'nce suggests that the species of this genus 

 possess pieoibital and pe<lal glands, but are without inguinal 

 glands. In the case of M. saliiaiia, both Owen and Ogilby are in 

 agreement aljout the presence of preorbital and the absence <>f 

 inguinal glands, and Ogilby adds that the pedal glands are also 

 present. 



Mauoqi;a pjiiLi.iPSiJ Thomas. (Lort Phillips's Dik-dik.) 



(Text-fig. 9().) 



Of this species I Jia\e examined, in the fresh state, one example 

 which agreed with the specimens of M. saltiana seen by Owen and 

 Ogilby in having preoi-bital and pedal glands, but no inguinal 

 glands. I\Tr. IJeddard also noted the absence of inguinal ylands 

 (P. Z. S. 1909, i. p. 188). 



The preorbital glands were small. The orifice was a small 

 vertical crescentic slit, with its concavity looking backwards, 



* I hen- adopt, without prejudice, Mr. U.C. \V rough ton's opinion that S. abj/ssinica 

 diflers from the southern form Cffrinnni in the sliortness of its ears. It is quite 

 immaterial to tiie work in hand whvthov abi/sshiira be specificallj' or subspecifically 

 distinct from </riiiimi, since tln" close relationship between the two is admitted by 

 everyone.
