of Peron and Lesueur than any other living species, although 

 evidently different. The M. ruficollis inhabits the neighbour- 

 hood of Port Western and Bass' Straits. 



C. 10. Portion of the humerus and ulna of a kangaroo, 

 which, from their proportions, belong probably to the 

 same species as specimens C. 4. and 5. 



Prom what precedes, it will appear that the fossil bones of 

 Wellington Valley present us with at least three species of 

 kangaroo, if not four, of which two are evidently distinct from 

 all the known varieties. I have been enabled to compare them 

 with the skeletons of all the species described by authors, with 

 one single exception, which is the Macropus rufus of Desmarest, 

 probably the M. Lanigerus of Hamilton Smith, a species inha- 

 biting the same district in which the fossils have been discovered. 

 To pronounce definitively, therefore, that the fossil belongs to 

 an unknov/n species, or one no longer in existence, it will be ne- 

 cessary to examine the skeleton of the M. Lanigerus, which can- 

 not be done at present, as no specimen exists in any European 

 museum *. 



D. Genus HALMATURUS- 

 D. 1. Fragment of the left superior maxillary bone, contain- 

 ing five molares in situ, of a gigantic species of this 

 genus. 



. This specimen is remarkable, as shewing the absence of the 

 bony palate, as far forward as the space which separates the 

 first and second molares; a character which, in some measure, 

 distinguishes this subgenus from the Kangaroos properly so 

 called ; since, in the latter, the bony palafe is in general either 

 perfect, or only pierced by a few small openings. 



.D. 2. Portion of the superior maxillary bone, with frag- 

 ments of two molares. 



D. 3. Fragment of the left Os innominatum of the pelvis of 

 an animal which appears to be referable to the same 

 as the two preceding specimens. 



D. 4. Mutilated os calcis of the same, animal. 



• We trust our friends in New Holland, by transmitting a skeleton and 

 skin of this species, which is found near Port Macquarrie, will enable us to 

 answer the important {juery stated above.-r-EDiT.
