apparently more bushy. In the Cameroons race {^D. a. batesi) the 

 markings on the under surface of the chin, throat, and chest are 

 yellow, and the face has a black chevron running from the muzzle to 

 the eyes. The light markings on the back are in the shape of yellowish- 

 white spots anteriorly, but on the loins form almost continuous yellow 

 bands, arranged alternately on each side of the middle line, where they 

 are interrupted ; there is one distinct yellowish flank-band joining the 

 transverse rump-band ; and the tail is brown at the base, which is the 

 only part known. It is just possible that the yellow in the one 

 specimen at present known from the Cameroons may be due to 

 staining, and if so, the description will, at least to a certain extent, be 

 wrong. 



In books on natural history the water-chevrotain is stated to 

 frequent the banks of streams, and to have much the habits of a wild 

 pig. According, however, to Major Powell -Cotton, it actually swims 

 and dives in the water, apparently much after the manner of a South 

 American capibara. It is thus really much more entitled to the name 

 duikerbok than is the animal to which that title properly belongs. A 

 female which lived many years ago in the London Zoological Gardens 

 gave birth to a single fawn ; the number of young at a birth in the 

 Indian mouse-deer is either one or two.

As previously mentioned, the three families of the hollow-horned 

 ruminants {Bovidce), giraffes and okapis {Giraffidce), and deer [Cervidce) 

 agree in the common feature of having crescent-shaped cusps on the 

 crowns of their cheek-teeth, and in lacking upper front teeth. They 

 also exhibit a mutual resemblance in the complex structure of their 

 stomachs, in the fusion of the two bones of the lower part of each leg 

 to form a cannon-bone, and likewise in the almost universal presence 

 of a pair of appendages of some kind on the head in at least the males. 

 In all these respects pigs and hippopotamuses differ from the above 

 type, having irregular warty or trefoil-shaped cusps on their hind cheek- 

 teeth, well-developed upper front or incisor teeth, comparatively simple 

 stomachs, no cannon-bone in the lower part of the limbs, and no horn- 

 like appendages on the head. As they also differ, although in a less
