is best developed on the internal side, while on the inferior molars it extends 

 further on the external side. 



A portion of the frontal bone preserved shows that the interorbital 

 reg-ion is flat, and that there is a strono: sasfittal crest. The chambers for 

 the large olfactory lobes fall below the anterior part of the sagittal crest. 

 The glenoid cavity of the squamosal bone is wide anteroposteriorly,and has 

 no anterior crest. The postglenoid foi'amen is rather large. The anteor- 

 bital foramen issues above the j^osteiior part of the third superior premolar. 



The proximal end of the humerus displays a well-developed, rather 

 flat, greater tuberosity (with a distinct teres facet), which is continued as a 

 prominent bicipital ci'est to the lower part of the shaft. The distal extremity 

 exhibits an epitrochlear foramen. A part of the shaft of the ulna is vei'y 

 robust; both sides are grooved. The shaft of the tibia is quite slender, with 

 the long diameter anteroposterior, the posterior edge acute on the inferior 

 tliird. The edge turns outwards, forming the posterior edge of the wide 

 tibular face. Internal malleolus pi'ominent distally, most so posteriorl3^ 

 The astragalar face is oblique and nearly flat, or slightly concave, having 

 even less excavation than that of most creodonta.

Tliis species was robust in its characters, and evidently lived on hard 

 food; its strong and worn canines show that they had more than the usual 

 use. In its dentition it stands nearer the creodonta than does any other 

 member of the group. It was probably a burro wer.
