are confirmed and additional information aftbrded by the anterior 

 molars of a young individual (PL xiv. fig. 3) in the comparatively 

 unworn state which preceded the eruption of p.'*. The anterior 

 talon of m. ^ is long and broad and its outer valley is subdivided 

 ])y a second fore link. The mesial Nalle}^ is closed on the inner 

 side ]jy a raised basal rim and sul)divided 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 

 lol^e. 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 lol)e to the inner end 

 of its crest. M. ^ lias no secondary fore link and no folds rising 

 from the outer mid valley, but in other respects repeats th(3 

 characters of m. ^. 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.— F.^ (PI. xiv. fig. 4). The fore end of the lobe 

 has on its inner side a shallow indent terminating below in a 

 small ledge w^hich represents an anterior basal talon. The hori- 

 zontal surface of al:)rasion 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.-^ (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 suddenl}^ dilated over the 

 intero-posterior angle, where a trans^e^'se field of dentine shows 

 the part of the tooth in earliest use. 



Molars. — (PI. xiv. fig. 2). With strongly linked Vjasal 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.
