forwards from its outlet, and a simple oblong and smooth surface 
of wear, 9 mm. in extent, inclined caudo-dorsad and distad. 
Premolar normal in shape ze. subtriangular, subequilateral, twin- 
lobed, the smaller constituent of the double lobe on the inner 
posterior angle, the larger occupying the outer moiety, the 
duplication indicated posteriorly by a deep valley descending to 
the base which is edged with a narrow post-basal ridge commencing 
on the outer angle and continued to the middle of the inner side, 
the inner fore side of the twin-cusp descending with a striated 
surface to a prebasal ridge extending from the tront angle of the 
tooth nearly to the middle of its inner side ; the crown planed down 
by wear to less than half of its criginal height, the dentinal area 
exposed bitriangular, oblique. ‘The anterior true molar @* worn 
nearly to its basal ridges ‘The succeeding molars diminishing slowly 
in degree of wear ; the hinder lobe of #z* as usual much contracted 
in breadth, descending a little below the level of those of the 
teeth anterior to it, and with its plane of wear ascending capito- 
dorsad ; the post-basal ridges of the molars feeble and short 
transversely, the hinder slopes of the posterior lobes with a 
shallow indent or valley, their front sides submesially protuberant, 
the protuberance representing a mid-link; the prebasal ridges 
wider, especially on the inner side, which is separated from the 
outer by a low fore-link. 
Intermaxillaries produced and deflected in front of the nasal 
aperture, tumid anteriorly for the lodgment of the incisor roots, 
which are mesially approximate. On the mid-line of the upper 
surface a small pyramidal process, and on either side of the middle 
of the fore edge of the nasal orifice a tubercle for cartilage attach- 
ment; the surface below the lateral edge of the nasal orifice tumid 
but suddenly compressed to form part of a concave area in front 
of the suborbital foramen; the maxillo-intermaxillary suture 
passine through this depression proceeds in its upward course 
nearer to the nasal aperture than to the orbit, and thus leaves a 
long suture between the nasal and nasal process of the maxillary ; 
the suborbital canal wide and short, with its large exterior foramen 
pierced through the anterior part of the long oblique root of the 
zygomatic process, which, on its antero-inferior side, is rather 
deeply excavated, the process but moderately exserted and inclined 
continuously caudad, the depending process long, descendingly 
obliquely with a slight backward curve much below the level of 
the upper molars, compressed fore and aft, and tapering slightly 
to a rounded terminal edge ; the nasals narrow, obtuse in front, 
and not completely covering the nasal orifice ; the upper profile
