Cope.] 76 [Feb. 17, 
are of subequal size, but their edges are differently worn. The first and 
second are squarely truncate, the third obliquely on each side, so as to 
give an angular apex. The inferior canine is robust, with the apex 
directed upwards. The section is subtriangular, with a rather obtuse apex 
anterior. The external face is flat, and has an open shallow longitudinal 
groove, which is cut by the face of attrition not far below the apex. En- 
amel smooth. The fourth premolar is a small tooth with one root entirely 
behind the canine. It is separated by a very short interspace from the 
third premolar. It is not clear whether it has one or two roots. The sec- 
ond premolar has a compressed simple crown without cingula. The pos- 
terior base is broken off. The first premolar has two subequal closely 
appressed cusps, anterior to the middle of the crown. In front there is a 
basal angle ; posteriorly a long heel, whose elevated longitudinal ridge is 
external to the middle line. 
The first true molar is wanting. The second displays a crown a little 
longer than wide. It supports four cusps, without intermediates, whose 
bases are joined so that wear causes their dentinal centres to become con- 
tinuous. A swelling in the valley represents the second intermediate 
cusp, while a similar swelling of the posterior cingulum represents the 
third. Cingula are represented by a posterior and anterior basal ledge. 
The third inferior true molar has two pairs of cusps and a large heel, the 
latter embracing a median basin. A low intermediate tubercle interrupts 
the middle of the anterior valley, and three low confluent tubercles fill 
the basin of the heel. The border of the latter is tubercular, the principal 
one being a little exterior to its median point. No cingula, but a short an- 
terior ledge. Enamel smooth.
