The incisor teeth (if the upper jaw are arranged so as to 
form a semi-oval figure; small, compressed, and when viewed 
from the outer or inner side, present nearly a square form; 
the two foremost are separated by a narrow space, the follow¬ 
ing three, on either side, form a continuous series with the 
first, hut the fifth is usually more or less separated from the 
rest. The canine is moderate, or large, compressed, pointed, 
and somewhat recurved, and distinctly separated from the 
false molars, as well as from the incisors. The false molars 
are more or less separated by intervening spaces, com¬ 
pressed, and, when viewed externally, present a triangular 
figure, hut at the base is a minute anterior aud posterior cusp : 
the two foremost of these teeth are two-rooted; the third, 
which is in contact with the true molars, is sometimes three- 
rooted, and has a small tubercle on the inner side. The 
crowns of the true molars are nearly square, hut broader on 
the outer side than the inner ; the masticating surface of each 
tooth presents eight more or less sharply-pointed tubercles, 
of which four form a longitudinal series on the outer side of 
the tooth, twT) are situated in the mesial line of the tooth, are 
larger than the rest, and are joined by oblique ridges 
to the outer tubercles, so that they form the apices of two 
triangles, two of the smaller tubercles marlring the angles at 
the base of each triangle; and, lastly, on the inner side of 
the tooth are two other tubercles situated opposite the two 
principal tubercles just described; their apices are much less 
elevated than those of the other tubercles; in some species 
they are of equal size, whilst in others the hindermost of 
these two eminences is very small h The hindermost of the 
upper true molars, it must he observed, will not agree with 
the foregoing description, since the crown of this tooth is of 
1 This is important to notice, for we shall find that it is the absence of this 
posterior inner tubercle which gives the triangular form to the crowns of the 
true molars in the Danyuridm.
