The following, to No. 5343 inclusive, are parts of the same skeleton of a young female 

 Australian, from Port Essington : 



Presented by J. B. Jukes, Esq., F.G.S. 



5337. The cranium. 



The last true molar is not developed. The alisphenoid joins the parietal on both sides of 

 the head. The styliform processes are unusually produced towards the ectopterygoid plates. 



5338. A thoracic rib. 5339. The right clavicle. 



5340. The humeri. 



The proximal epiphysis is wanting : there is a large intercondyloid perforation : the distal 

 epiphysis is in three pieces, one forming the radial tubercle, a second forming the sigmoid 

 cavity, and a third forming the inner condyle. 



5341. The right ulna. 



The distal epiphysis is wanting. 



5342. The femora. 



The distal epiphysis is wanting. The head and great trochanter remain attached to the 

 left femur, but the head is wanting in the right femur. 



5343. The shafts of the tibiae. 



They present the characteristic compression and anterior convexity. 



5344. A great portion of the calvarium of a skull of an Australian, of Port Adelaide. 



Presented by Governor Sir George Grey, C.B. 



5345. The cranium of an Australian child, from Van Diemen's Land. 



On the left side a wormian ossicle is interposed between the alispheuoid and parietal, on 

 the right side two such ossicles are interposed. The characteristic large size of the crowns 

 of the first true molars is well shown, although they are yet in their formative alveoli.

Besides the narrow cranium, with its contracted and retreating forehead and the progna- 

 thic jaws common to the Melanian races, the Australian skull is characterized by the thick 

 and prominent superorbital ridge; which is continued across the glabella and overhangs the 

 deep-set, small, and slightly prominent nasals : another well-marked characteristic is seen in 

 the large proportional size of the molars, premolars and canines, but more especially of the
