are confirmed and additional information afforded by the anterior 
molars of a young individual (PL xiv. fig. 3) in the comparatively 
unworn state which preceded the eruption of p. 4 . The anterior 
talon of m. 1 is long and broad and its outer valley is subdivided 
by a second fore link. The mesial valley is closed on the inner 
side by a raised basal rim and subdivided by a low linking ridge. 
A broad tapering fold rises upon the face of the fore lobe flanking 
the outer valley and a feebler one on the opposed face of the hind 
lobe. The posterior talon is very short, but, like the anterior, 
continuous from side to side; from its inner third a broad tapering 
fold or link rises obliquely upwards on the lobe to the inner end 
of its crest. M. 2 has no secondary fore link and no folds rising 
from the outer mid valley, but in other respects repeats the 
characters of m. 1 . In both teeth the inner side of the front 
talon is broader and deeper than the outer, hence its more per- 
sistent appearance in old age. 
Mandibular. — P. 4 (PI. xiv. fig. 4). The fore end of the lobe 
has on its inner side a shallow indent terminating below in a 
small ledge which represents an anterior basal talon. The hori- 
zontal surface of abrasion is almost wholly on the inner side of 
the central line. The link connecting the lobe with the basal 
talon is wide and elevated. There is a feeble impression behind 
the middle of the outer surface of the crown. 
P. 3 (PI. xiv. fig. 1) is oblong with a large basal talon simu- 
lating a posterior lobe; this is linked to the lobe proper, but the 
link is on the outer side ill-defined. Fore end of lobe so impressed 
on each side as to give it the appearance of possessing a basal 
talon with a high linking ridge. Crown suddenly dilated over the 
intero-posterior angle, where a transverse field of dentine shows 
the part of the tooth in earliest use. 
Molars. — (PI. xiv. fig. 2). With strongly linked basal talons 
fore and aft, the mesial and anterior links descending forwards 
from the outer angles of the lobe yield surfaces of abrasion peculiar 
in pattern.
