details as basic data on the teeth are of importance and are therefore 

 given here in full : 



Anterior left lower premolar. Crown or surface view. Human dimensions and 

 general pattern. On the buccal surface a circle segment-like facet of wear by 

 the upper caninus. On the mesial side an irregular concave facet of contact with 

 the lower caninus. At the summit a strongly developed buccal cusp. No lingual 

 cusp, on its place only confluence of the lingual and connecting transverse rim. 

 The latter dividing the crown surface into a small anterior and a large posterior 

 fossa. A ridge starting from the inner side of the (buccal) cusp descends in the 

 posterior fossa. The same is seen in many anterior lower premolar crowns of 

 anthropoid apes. Distally of (behind) the (buccal) cusp a surface of wear by 

 the anterior upper premolar. 



Mesial (anterior) view. Showing the inward bending high buccal, the in- 

 ward sloping upper and the low lingual side of the crown. Below and before the 

 cusp the irregular facet of contact with the lower caninus. Bipartite lower part 

 of the root, the point of the lingual-distal part broken off. 



Distal (posterior) view. Near to lingual side a crescent-like facet of contact 

 with the lower posterior premolar. 



Lingual (internal) view. Low lingual crown side. The two fossae. Broaden- 

 ing of the crown upwards. Oblique position of the root (directed backwards). 



Buccal (outer) view. Circle segment-like facet of wear by the upper canine. 

 High buccal crownside. 



Penultimate left upper molar. Crown or surface view. Surface smoothly worn 

 off. The buccal-distal cusp part small, very much as in many homonymous orang- 

 utan molars. Strongly divergent roots. 



Root view. Single lingual root. Buccal root (in this individual) composed 

 of three fused elements, one distal (posterior) and two mesial (anterior) ones. 



Mesial (anterior) view. A large semi-ovoid facet of contact with in} Buccal 

 and lingual roots strongly divergent, the lingual root departing mostly from 

 the vertical line. 



Distal (posterior) view. Ellipse-like facet of contact with vt.^ 



Lingual (internal) view. Direction of the roots backwards. 



Buccal (external) view. The root showing the two fused buccal elements. 



Last right upper molar. Crown or surface view. Little worn. Moderately 

 wrinkled, much less so than in orang-utan. Semi-ovoid as in some orang-utans, 

 by moderate development of the distal-lingual and excessive reduction of the 

 distal-buccal cusp. The crown as a whole shows reduction. The constriction, 

 towards the masticatory surface indicates late piercing of this tooth. 



Root view. Of the strongly divergent roots the buccal one of this individual 

 composed of three fused elements, one of which distal and two mesial. 



Mesial (anterior) view. Likewise as in Fig. 30 the lingual root mostly de- 

 parting from the vertical line. No facet of contact with in/' probably a conse- 

 quence of the still little use of the tooth on this side. 



Distal (posterior) view. Lingual (internal) view. Buccal (external) view. 

 Roots strongly directed backwards, more so than those of w.^ 



THE FEMUR 



The femur is nearly complete and little injured. Some marks of 

 '' crocodile teeth " are to be seen at its upper portion. " The large ex-
