40 SKETCH OF THE HISTORY OF MAMMALIA. 



the position and character of the cuticular furrows des- 

 tined to facilitate the lateral motions of the head are very 

 different. Besides these, Dr. Smith states that many 

 other diagnostic characters might be instanced ; such as 

 the black mark on the inside of the thigh of the keitloa, 

 the distinctly produced tip of the upper lip, and the 

 comparatively few wrinkles on the snout and parts around 

 the eyes. 



The first example of this animal which Dr. Smith met 

 with during his expedition was shot about 180 miles 

 N.E. of Lattokoo, but considerably south of the country 

 to w liich the species appears directly to belong, and from 

 which it might be considered as a wanderer. On the 

 expedition penetrating to the northward of Kurrichane, 

 every one was found conversant with the name, and able 

 to direct to situations where the animal was found. Few 

 mentioned the keitloa without alluding to its vindictive 

 temper and ferocity ; and those, says Dr. Smith, who 

 had sufficient confidence in the party, compared to it a 

 chief then awfully oppressing that part of the country, 

 and spoke of the man and the animal as alike to be 

 feared. As the party advanced, the keitloa became 

 more common, though it never occurred in such numbers 

 as the other two species. 



'* The interest," says Dr. Smith, " which the discovery 

 of this species excited, led to the making of minute 

 inquiries as to the animals of this genus; and the expe- 

 dition had sufficient reason to believe, from the replies 

 to constant questions, that two other undescribed species 

 existed farther in the interior, one of which was de- 

 scribed as being something like the keitloa, and having 

 two horns — the other as differing in many respects, and 

 having only otie horn. The keitloa browses on shrubs 

 and the slender branches of brushwood, using the upper 

 lip as an organ of prehension." 



The White or Blunt-nosed Rhinoceros 



(Rh. simus). 

 Termed Mohoohoo by the Bechuanas, is larger than the 

 two former species, being upwards of twelve feet in
