HUMERI. 



Right Left 



Humerus. Humerus. 



Total length (rubbed) .. .. .. 224 mm. 228 mm. 



Greatest proximal width 56 mm. 57 mm. 



Least proximal width 50 mm. 51 mm. 



Girth of shaft including the pec- 

 toral ridge 103 mm. 101 mm 



Head to deltoid tubeixle 90 mm. 95 mm. 



End of supinator ridge to the onte- 



picondylar foramen 60 mm. 63 mm. 



Articular width of distal condyles 46 mm. 46 mm. 



That these two humeri are the associated arm bones of 



the same skeleton as that which supplied the ramus of the 



mandible, there seems to be no reasonable doubt, and the 



same applies to the appended descriptive data collected from 



the other bones available to us. 



FEMORA. 

 Unfortunately, neither femur is intact, the left being only 

 represented by the shaft, while the right supplies a shaft, 

 and a complete distal end, but fails us at the floor of the 

 trochanterian fossa. In these circumstances we are with- 

 out knowledge as to the actual head, but the information 

 supplied by these two bones leaves us in no doubt as to the 

 kind of femur that obtained in this fossil skeleton. Seen 

 in profile, the shaft is straighter than in modern animals, and 

 the rotular groove does not ascend the shaft as in our living 

 Wallabies, but spreads itself out into a more decided rotular 

 fossa, the upper wall of which slowly subsides upon the sur- 

 face of the shaft. Muscular scars and foramina are similar, 

 and the condyles agree fairly well upon all their articular 

 faces, but the intercondylar fossa is formed at an equal cost 

 to either condyle, and not at a marked toll upon the internal 

 condyle as in the Wallaby of to-day.
