J511 1 . A portion of the right ramus of the lower jaw of a large male Red Kan-

1512. A fragment of the right ramus of the lower jaw of the Macropus Titan, 

 with the posterior part of the last molar tooth, which shows the charac- 

 teristic absence of the posterior talon in this great extinct species as 

 compared with the Macropus Atlas : the depth of the jaw at the poste- 

 rior part of this tooth is one inch two lines ; the corresponding part of a 

 very large male Macropus laniger is eleven lines : the wide excavation 

 at the base of the coronoid process, which is continued into the dental 

 canal, is well displayed in this fossil.

 mine River, west of Moreton Bay, Australia.

1513. A considerable proportion of the left ramus of the upper jaw of an im- 



mature Atlas Kangaroo {Macropus Atlas, Owen), containing the two 

 deciduous molars and three of the permanent molars ; the last is muti- 

 lated. The crown of the large premolar, characteristic of the present 

 species, is exposed from the inner side in its closed alveolus. From the 

 size of the teeth this specimen appears to have belonged to a young 

 female.

 mine River, west of Moreton Bay, Australia.
