150 MR. WATERHOUSE ON A NEW 
The upper jaw is furaished with eight minute, pointed, and slightly compressed in- 
cisors, the anterior pair of which have their apices only apparent, being on a level with 
the gum; the three next pairs project slightly from the gum: after these follow two 
canines, which are of a compressed and pointed form, and have their posterior outline 
somewhat recurved. The false molares are also compressed ; their form approaches to 
that of a triangle, having the apex recurved. The first two on each side have an 
obscure notch anteriorly and posteriorly ; in the next pair these notches are more di- 
stinct, but the central lobe is less than in the foregoing false molars. 
The first pair of true molars are small and compressed, they have two minute tuber- 
cles anteriorly, and two posteriorly ; these two pairs of tubercles are separated by a 
considerable chasm, on the inner edge of which, and in the centre, another small 
tubercle is perceived. The second pair of molars are of a larger size than the last- 
mentioned ; their crown presents nearly a semicircular figure, and consists of several 
obscure blunt tubercles, arranged in three principal masses; one placed anteriorly, 
another posteriorly, and the third internally. The third pair of molars are shorter and 
broader than the second; their crown consists of three large blunt tubercles arranged 
in a triangle, and disposed in the same manner as the three masses of tubercles of the 
preceding pair of molars. The fourth pair of molars are of the same general character 
as the third. The fifth and last pair are very small ; their crown is of a triangular form, 
and consists of three obscure blunt tubercles, two of which are placed in a line parallel 
to the occipital portion of the skull. 
In the lower jaw the incisors are about the same size and form as those of the upper, 
if we except the front pair, which are large and compressed ; they project forwards, and 
are somewhat recurved at the apex. The canines and false molars of the lower jaw are 
also of the same size and form as those of the upper; the last pair of false molars, 
however, are similar to the preceding pairs. The first pair of molars are minute and 
compressed, and the portion above the gum consists of three sharply-pointed tubercles 
arranged in a line. The second pair exceed the first in size, and exhibit three tubercles 
as before. The three following pairs of molars are of the same character, but they have 
each four sharply-pointed tubercles, arranged in a line, and some blunt tubercles situ- 
ated at their base on the external side. The last pair of molars resemble the preceding, 
excepting that they are of a smaller size, and possess only three sharp tubercles.’ 
In the lower jaw the posterior false molars have somewhat of an inward inclination, 
but in the true molars this inclination is more evident ; indeed it appears as if the ex- 
ternal sides of the lower teeti were opposed to the crowns of the upper; but upon 
examination we find that the inner side only of each tooth is properly developed, and 
constitutes the sharply-pointed tubercles above described: the outer side of these 
teeth consists only of blunt tubercles, which are scarcely elevated above the gum. 
This form of tooth evidently arises from the inward inclination of the edge of the 
lower jaw. 
Owing to the narrow and elongated form of the snout, the incisors are placed late-
