Phillip's Dik-Dik is larger than Swayne's, and alsover}' differ- 

 ently colored, its rich rufous, almost at times, mahogany flanks, 

 presenting a strong contrast to the dark back and pure white 

 belly. In some individuals this red color intrudes so far upon 

 the white of the under parts as to leave merely a narrow white 

 line in the center of the breast and belly. Placed side by side 

 in a considerable series as that now before me, the strong differ- 

 ence in color between these two small antelopes is very apparent. 



A remarkable peculiarity of these little animals is the immense 

 deposit in the antorbital vacuity of a black pigment, which stains 

 everything it touches. It forms a swelling just in front of the 

 eye and from its jet black color and considerable size makes a 

 very conspicuous mark. No trace of this exists in the skin, 

 and as the skull shows a cavit}^ at this point, no one would 

 imagine that there would here be a prominence on the face 

 instead of a depression. The lack of knowledge of such facts as 

 this causes the mounted specimens in museums to appear totally 

 unlike the living animal, more caricatures than the real object, 

 and I have never seen any drawing that correctly represented a 

 Dik-Dik. Waller's gazelle is another species possessing a simi-
