are nearly equally developed, the ridges bemg high and edged with 

 enamel ; the rest of the teeth are minutely rugulose ; the hinder 

 edge of the third grinder is on a line even with the front edge of the 

 hinder nasal opening. The skidl is 12 inches from the intermax- 

 illary to the convexity of the condyle ; the teeth-line is 4| inches 

 long. The facial portion (that is, the skull from the front of the 

 intermaxillary to the front edge of the internal nostril) iS only two- 

 fifths of the entire length ; it is the same length as from the front 

 edge of the internal nostril to the suture between th« basisphenoid 

 and the basioecipital bone. Length from intermaxillary to front 

 edge of internal nostril or end of palate 4 inches 7 hues, from end 

 of palate to convexity of occipital condyle 7| inches. The iater- 

 maxiUary of one side is lost ; the other has a narrow lower edge, 

 not showing any appearance of cutting-teeth. The nearly hemi- 

 spherical prominence on the nose is hollow, with thin even parietes ; 

 the cavity extends far back, and is open behind. The face, from 

 end of nasal to the front edge of the orbit, is shorter than the 

 part of the skull behind it, being from front end of nasal to front 

 edge of orbit 5 inches 4 lines, from front edge of orbit to occi- 

 pital crest 7 inches 2 lines. Nasal bones short and broad, being 

 about two-sevenths of the entire length of the skuU to the occipital 

 crest. 



The lower jaw shows four grinders and a cavity behind the fourth ; 

 the second and third grinders are most developed, raised above, the 

 alveolus, and furnished with a smooth enamel edge ; the first small 

 grinder is just showing, as is also the case with the fourth grinder, 

 which is rather more developed than the front one ; neither of these 

 teeth is raised above the edge of the alveolus ; the front edges 

 marked with two or three series of smaU circular pits j but no cut- 

 ting-teeth are visible. 



In the Free Museum at Liverpool is the head of a large specimen, 

 collected by Mr. Burke in Lord Derby's exploring party. The skin 

 of the head is stuffed, and the skuU kept separate. 



An adult skull without the lower jaw is in the Museum of the 

 London Missionary Society in Bloomfield Street, London, E.G., that 

 was obtained by the Eev. John Campbell. 



The Eev. John Campbell gives a figure of the head of this animal 

 before the skin was removed, in his work entitled 'Travels in South 

 Africa, Second Mission' (2 vols, 8vo, London, 1822), where it is 

 called the " head of a Unicom killed near the City of Mashow " 

 (plate at p. 294 of the second volume). The artist has added a 

 regular series of nearly equal-sized square teeth all along both 

 jaws. 



This figure is copied in Froriep's ' Notizen ' for 1822, at vol. ii. 

 p. 98 ; and a notice of the skull is given at p. 152 of vol. i. of the 

 same journal.
