D. 5. First dorsal vertebra of the same. 



D. 6. 17th caudal vertebra of the same. 



D. 7. Inferior part of the left tibia of an animal allied to the 

 genus Kangaroo, although differing in the details of 

 its configuration. From all the living specimens I have 

 examined, it belongs, probably, to the same animal as 

 Nos. 1. 2. and 3. 



D. 8. Fragment of the left humerus of the same species. 



I have reason to believe that all the specimens from D 1 to 

 8 inclusive, belong to the same species of Halmaturus, very 

 different from any animal now in existence. 



The genus Halmaturus, as re-established by Frederick Cuvier, 

 and which is well characterized by its five persisting molares, — 

 by the tail not covered with fur, as in the ordinary kangaroos, 

 and by other anatomical characters, consists at present of 

 only two species, the Macropus fasciatus, or elegans, and the 

 Halmaturus Thetis of Frederick Cuvier, the former scarcely 

 equal in size to a rabbit, and the second of the size of the fox. 

 The fossil remains above noticed belong to an animal exceeding 

 in stature the largest species of kangaroo by one- third. We 

 may reasonably, therefore, conclude, that these fossils belong to 

 a species unknown to zoologists, and probably extinct at the 

 present day. 



D. 9. Fragment of the superior maxillary bone, containing 



four molares of a smaller species of Halmaturus. 

 D. 10. Two fragments of the superior maxillary bone, with 

 four molares, of a still smaller species of Halmaturus, 

 nearly allied to the Halmaturus Thetis of Frederick 

 Cuvier.' 

 D. 11. Left femur entire, of a small species of Halmaturus, 

 which, from its proportions, appears to me to belong 

 to the same species as preceding specimen — it differs 

 in form from all the living specimens with which I 

 have compared it. 

 D. 12. Id. id. id. 



D. 13. Fragments of the same. 

 D. 14. Inferior extremity of the same. 

 D. 15. Fragment of the right tibia of the same species. 

 D. 16. Upper extremities of the right tibia and fibula.
