progressively backwards, showing elongated inferiorly keeled 

 centra. The third lumbar, figure 26, has a spine of moderate 

 06 height, and simple, cylindrical poste- 



rior, and hollow, half cylinder-like an- 

 terior zygapophyses, and distinct ana- 

 pophyses and metapophyses. There 

 is apparently no trace of the double 

 tongue and groove pattern of certain 

 of the contemporary Creodonts. The 

 sacrum is composed of three anchy- 

 losed vertebrae, and there was a long

K J * > damaged condition. lhe glenoid 

 cavity is elliptical and cup-shaped ; the neck is very short, the 

 unusually heavy spine rises close to the glenoid border, as in 

 the Binturong, and there was a prominent metacromion 

 present. 



The humerus, figure 27, is complete, but considerably crushed 

 laterally ; it exhibits the following characters : The head is well 

 rounded, pyriform, and overhangs the axis of the shaft pos- 

 teriorly; the greater tuberosity is inconspicuous, and does not 

 reach the level of the head ; the deltoid crest is large and 

 extends well down the shaft; the distal extremity is broad, 

 with large supinator ridge and internal condyle, and there is 

 an entepicondylar foramen. 



In its proximal portion, the ulna, figure 29, exhibits some 

 peculiarities of structure to which that of the Binturong 

 makes a very decided approach. The chief peculiarity is seen 

 in the upward curvature of the under surface of the olecranon 

 and its great lateral breadth. Upon its inner or radial side, it 

 is produced in such a way as to form a broad shelf -like projec- 

 tion, as in the Binturong ; it is relatively short and thick as 

 in this latter species, in marked contrast with its elongated form 

 in many of the contemporary Creodonts. The posterior wall of 

 the greater sigmoid cavity has comparatively little elevation, 

 giving to the cavity a shallow appearance, but the anterior 

 boundary or coronoid process is prominent and well extended 

 upon its radial side. Just in front of this latter process is seen 

 the deep muscular impression for the attachment of the tendon 

 of the anterior brachial muscle. The shaft is considerably 

 flattened from side to side and traversed by broad shallow 

 longitudinal grooves, which continue to the distal end. In the 

 lower fourth of its extent, the shaft becomes sharply triangu- 

 lar in cross-section by reason of the development of a sharp 

 ridge from the more or less rounded internal surface. This
