and less perilous conditions of life enjoyed by a Sirenian tenant of 

 fresh waters. Leaving this question, however, to the discoveries 

 of my fellow- students, I opine that the present relic is the first 

 indication we have had of the existence of the animal. And in 

 expectation of that increased knowledge of its structure which will 

 doubtless be the fruit of further research, I propose to give it 

 recognition under the name of Chronozoon Australe. The fossil 

 was procured from the Chinchilla (Darling Downs) drift, in which 

 it was of course associated with crocodiles, turtles, ceratodus, &c, 

 together with land animals. 



Remarks on a Skull of an Australian Aboriginal from 



the Lachlan District. 



By Baron N. de Miklouho-Maclay. 



Plate 18. 



The cranium, which, through the kindness of Mr. C. S. Wilkinson, 

 I have had for inspection, is not complete (the right temporal bone, 

 the greater part of the sphenoid and the ethmoid bone are absent), 

 but in a fair state of preservation, which circumstance makes me 

 suppose that the owner of the same died not long ago, and that 

 the skull has not remained long in the ground. 



This cranium of a probably male Australian aboriginal, of very 

 likely over forty years of age (the sutura sagittalisis not very 

 distinct), is remarkable not only on account of a very pronounced 

 dolichocephalism (breadth-index 66.8), but also for the peculiar 

 formation of the occipital bone. The superior curved lines with 

 the external occipital protuberance of the above-named bone form 

 a very prominent occipital curved crest, larger than in any of the 

 skulls I have ever seen before. None of the skulls of Australian 

 aborigines in the Australian and Macleay Museums present such 

 a prominence of the superior curved lines. The hindmost point of 

 this skull is the occipital protuberance, and not the convex part of 

 the upper portion of the occipital bone, (the so-called occipital 

 point), as is the case in most human skulls.
