GENUS— MACROSCELIDES. 
I lie corresponding teeth in all the South African species agree in very many points, and thus 
t le general resemblance may be said to be very strong. Minute examinations, however, 
. lvu ge many we d-marked differences which are more easily perceived than described. Each 
jaw contains twenty teeth, ten on each side. In the upper jaw, the series of one side is 
separated from that of the other at the anterior point of the intermaxillary bone ; in the lower 
jaw no division exists, the two anteriormost teeth being in juxta-position. For the sake of 
convenience, we may consider the teeth of each jaw under three divisions, viz. incisors, false 
molars, and true molars. The incisors are six in number, and in the upper jaw are lodged in 
the intermaxillary bones ; the false molars are two on each side ; the remainder are classed as 
true molars. In M. typicus the teeth of each side are continuous, but in the other species 
several of the anterior ones are more or less apart from each other. With respect to form the 
incisors of the upper jaw differ but little from each other, they are all laterally compressed 
the inner surface of each is distinctly concave, and the outer slightly convex, the two anterior- 
most ones are slightly longer than the other four, and all have an oblique cutting edge, the 
most projecting point of which is at the front of each tooth. The false molars are very & short, 
compressed, and slightly bicuspidatc, the one point immediately behind the other. The true 
molars are quadncuspidate, two points on the outer edge and two on the inner, but the latter 
never reach the level of the former; hence the crown of each tooth exhibits an inward slope - 
m the hindermost molar the two posterior points are always but imperfectly developed The 
mtisors of the under jaw are more compressed than those of the upper; the two false molars 
resemble closely those of the upper jaw, the first and second true molars have more the 
appearance of false than true ones ; indeed, they might with more propriety be ranked with 
tie former than the latter; they are strongly compressed and faintly tricuspidate, the points 
being disposed in a longitudinal line : the three hindermost molars are quadricuspidate, and 
the external and internal points attain the same level.
