Finally, I should be very much obliged to any gentleman who 

 can at any time give me notice of a " Kangaroo Drive" about to 

 take place in any accessible part of the colony. 



Ox Remains of an Extinct Marsupial. 



By C. W. De Vis, B.A. 



It most frequently happens that bones obtained from the 

 Queensland drifts are confusedly scattered specimens, having 

 indeed a certain value of their own, but often demanding of their 

 specifier a large use of that "wise and well-founded conjecture" 

 which is not always within reach. Every association of congruous 

 bones is therefore of value — generally of sufficient value to be placed 

 on record, however mistaken inhis conclusions drawn from the bones 

 themselves the recorder may chance to be. A belief in this, has 

 prompted the following observations on a collection of fragments 

 in a precisely similar state of preservation, and evidently belonging 

 to the same individual, obtained together in Gowrie Creek, with 

 much pains and patience by my friend, Mr. Henry Tryon. From 

 these fragments, it has been found possible to reconstruct a few 

 bones in portions, sufficient to guide us among the probable 

 affinities of their whilom owner. Fortunately, one of the relics is 

 a molar tooth — a deciduous grinder of a young animal, the 

 epiphyses of whose long bones were as yet non-adherent. The 

 tooth is 14 lines in length, 10 J lines in its anterior, and 9 lines in 

 its posterior transverse diameter. Though worn down nearly to a 

 level with the gum, the disposition of the enamel shows that it had 

 two nearly equal transverse lobes, a strong tubercle opposite to the 

 inner entry of the valley, no median or other link, no cingulum 

 and no anterior valon. On the inner half of the hinder edge of 

 the base, a sinus of enamel indicates that an accessory cusp rising 

 therefrom, with an outwardly-directed and expanding concavity, 

 was applied to the hinder lobe posteriorly, much as in the true 

 molars of Macropus Titan. The fangs, partially absorbed, are two 

 in number — the upper part of the front surface of the anterior and
