length of the skeleton is 20.3 which is even greater than 

 that given by Humphrey for Bushmen. The relation of 

 the radius to the stature is 15.6 which is approximately 

 the figure given by Hovelacque and Herve. The relations 

 of the femur and tibia to the skeleton are 26.8 and 23.2 

 respectively. The antibrachial index is 80.3 which is 

 very high, and approximates that of the higher apes more 

 closely than does the same index in the African negro. 



The torsion of the humerus is 136 degrees. According 

 to Hovelacque and Herve, the degree of torsion of the 

 humerus in the human family is lowest among the Aus- 

 tralians. 



SKULL. 



The skull is remarkable in many ways. The general 

 surface is very smooth and it is almost impossible to make 

 out any muscular ridges. In addition to the sutures 

 which are normally closed in an individual of this age, 

 the following are more or less completely synostosed : 

 the coronal, sagittal, lambdoidal, spheno-frontal, spheno- 

 parietal, malo-zygomatic, malo-frontal, nasal, naso-maxil- 

 lary, intermaxillary, palato-maxillary and interpalatal. 

 The original degree of serration of the cranial sutures 

 cannot be determined. 



Norma lateralis. — There is a considerable amount 

 of alveolar prognathism, rather more than one usually 

 finds in an Australian skull. The teeth are nearly hori- 

 zontal. The nasal spine is heavy and prominent, a char- 

 acter not usually associated with the lower types of crania. 

 The nasal bones are not prominent. The glabella, while 

 very highly developed, is entirely obscured by the enor- 

 mous development of the superciliary ridges. The inion 

 is equally massive and projects downwards so that it sup- 

 ports the posterior region of the skull. The mastoid 

 processes are not prominent. The temporal ridges can
