The type of this species consists of a very complete and 
well preserved left mandibular ramus. It belonged to an ani- 
mal about the size of the black bear. The mandible is long 
and proportionately slender. Posterior depth but little greater 
than anterior. Masseteric fossa very deep, its anterior border 
ending directly below the third molar. Anterior mental fora- 
men directly below middle of second premolar. Posterior 
mental foramen directly below posterior root of third premolar. 
Surface between anterior margin of masseteric fossa and a point 
below the middle of the sectorial quite concave. Inferior bor- 
der nearly straight from synphysis to a point directly beneath 
the posterior border of the second molar, when it rises quite 
rapidly to the angle, much as in the badger (Meles taxus) thus 
suggesting the specific name. The angle is considerably 
expanded transversely for the attachment of the masseter 
muscle. The exterior border of this expansion is on a line 
with the base of the teeth. The condyle is strong. The cor- 
onoid process is quite high and proportionately somewhat 
slender. Its upper and anterior borders, especially the latter, 
are considerably expanded transversely to give greater surface 
for the attachment of the temporal muscle. The inner border 
of the ramus is a nearly plane surface, except anteriorly 
where it is strongly convex. The dental foramen is situated 
about midway between molar three and the angle, and is on a 
line with the alveolar border. The symphysisis small and 
triangular in outline, and is extended somewhat below the 
inferior border of the jaw. Its supero-inferior diameter is 
about twice that of the antero-posterior diameter. : 
The Teeth: The incisors are missing, but they are represen- 
ted by three somewhat shallow alveoli crowded closely together. 
The internal and middle incisors were about equal in size and 
quite small. The latter was crowded considerably backward 
out of line with the external and internal. The external incisor 
was considerably larger than incisors one and two. The 
canine is only moderately strong and is oval in cross-section 
at the base. The first premolar is missing, but the alveole is 
well preserved and shows it to have been of moderate size and 
fixed by one root only. There is a diastema between it and
