left side, and thus behind the tip of the penis. The point to 

 notice is that t lie end of the urethral canal is not prolonged as 

 a special tubular process beyond the glans, whereas according 

 to Garrod this canal is produced in Guevei maxwelli and 

 monlicola into a long almost filiform termination, recalling 

 that of the sheep and goats, the shape of the glans otherwise 

 being as in Cephaloplms (Proc. Zool. Soc. 1877, p. 10, 

 fig. 20). 



Genus Sylvicapra, Ogilby. 

 Sylvicapra coro)iata, Gray (p. 873). 



The description and figure of the inguinal glands of this 

 species published in 1910 were taken from immature male 

 specimens from various parts of Nigeria. They were stated 

 to be wide shallow pits, much shallower than the corresponding 

 glands of Cephaloplms dorsalis. 



In an adult female of the same species from Nigeria 

 (W. A. Clayton} I found the gland to consist not of a definite 

 and deep pocket, as in Cephalophus, but of a long, oblique, 

 gutter-like depression of the integument overlapped by a flap 

 of skin in front. 



I find nothing to add to my description of the preorbital 

 and pedal glands. 



Sylvicapra grimmia, Linn. 



Of this species I was able to describe only the pedal glands 

 in 1910. 



The inguinal glands in three examples subsequently re- 

 ceived from various parts of South Africa had inguinal 

 glands like those of S. coronata described above — that is to 

 say, each gland consisted of a gutter-like groove lying in the 

 angle formed by the junction of the femur and the abdomen. 

 In one specimen, a female, the ends of the groove were over- 

 lapped by a small flap of skin forming a very shallow pocket. 



From the material available it appears that the inguinal 

 glands of Sylvicapra differ very markedly from those of 

 Cephalophus, where they consist of deep narrow pockets. 



A further difference between the genera, apart from that 

 supplied by the direction of the horns, is to be found in the 

 penis. In a male of Sylvicapra grimmia the extremity of the 

 penis was much less expanded than in the example of Cepha- 

 lophus dorsalis described above, and the urethral canal was 

 prolonged by a slender tubular process beyond the tip of the 

 glands, recalling the similar process found in many antelopes 

 and other Bovine Ruminants.
