180 THE WASATCH AND BRIDGER FAUN^. 



rior angle of the malar bone forms the inferior half of the anterior border of 

 the orbit, but its inferior part is supported by a peduncle of the maxillary 

 bone. Its posterior angle extends as far posteriorly as the external border 

 of the glenoid cavitv. The occiput is vertical, and is wider than deep. It 

 is convex in the position of the vermis, and concave on each side above the 

 occipital condyle. The condyles are rather small, and are widely sepa- 

 rated, bounding a very large foramen magnum. Inferiorly the basiocci- 

 pital is flat in front of the condyles. Between the otic bullae it has a median 

 keel, with a concavity on each side, bounded externally by a prominent 

 desceiuling border in contact with the bulla. 



The massateric fossa of the mandible reaches the line of the posterior 

 border of the penultimate molar tooth. The articular service of the condyle 

 is nearly round, and is strongly convex, and projects as far backwards as a 

 vertical line drawn from the angle. The coronoid process is much higher, 

 and has a wide summit with a convex border. 



(^f the superior molars, the apex of the minute first is bifid, one cusp 

 being the larger ; the second is a little narrower than the third, and the 

 fifth is a little wider antero-posteriorly. The enamel is smooth on all the 

 teeth in both jaws, including the incisors, and there are no cingula. 



"^riie extremities of the coracoid and acromion are about in one hori- 

 zontal line. The former is abruptly turned backwards and truncate on the 

 external face. 



The ulna and radius appear to have lost their epiphyses ; allowing for 

 this, they are a little longeithan the humerus. The shaft of the ulna is 

 rather compressed, while that of the radius in round in section. The distal 

 expansion of oach is about equal. The trnclianteric fossa of the femur is 

 very deep, and the little trochanter is very large. The third trochanter is 

 represented by a low ridge. The distal extremity of the tibia has nearly equal 

 anterojjosterior and transverse diameters, and the shaft at the distal two- 

 fifths the length is nearly round.
