GENEEICALLY UNDETERMINED SPECIMENS. 



A considerable number of the following specimens of limb-bones 

 and vertebrae belong in all probability to Macropus, but others 

 doubtless to the three preceding genera. With the exception of 

 some of the bones of the hind foot there appears in the majority of 

 cases no evidence for referring individual specimens to one genus or 

 species rather than to another, although the very large size of the 

 skull of Palorchestes indicates that the largest limb-bones probably 

 belong to that genus. 



The following series comprises merely a selection of the less im- 

 perfect specimens, from the very large collection preserved in the 

 Museum. 



44198. The glenoidal extremity of the right scapula of a large 



species ; from King's Creek, Clifton, Queensland. 



Presented by Dr. George Bennett, 1873. 



44198 a. The corresponding portion of a similar left scapula ; from 

 the same locality. Same history. 



43378. The corresponding portion of a slightly smaller right scapula ; 

 from the same locality. Same history. 



43384. The corresponding portion of a rather smaller left scapula; 

 from the Condamine River. Same history. 



43964. The corresponding portion of a still smaller right scapula ; 

 from King's Creek. Same history. 



38775. The proximal half of the right humerus of a very large 

 form ; from Queensland. This specimen agrees in relative 

 size with the femur No. 38619*, which is referred by 

 Owen to Palorchestes. 



Presented by F. N. Isaac, Esq., 1861. 



43370. The entire right humerus of a slightly smaller animal ; from 

 (Fig.) Clifton, Queensland. Figured by Owen in the 'Extinct 

 Mammals of Australia,' pi. cxii., and referred to Macropus 

 titan it agrees, however, much more nearly in relative 

 size with the femora referred by the same writer to Palor- 

 chestes, and could not possibly have belonged to the same 

 species as the femur No. 47830, which Owen refers to the 

 former. Presented by Dr. George Bennett, 1872. 



44199. The proximal extremity of a similar right humerus ; from 

 (Fig.) Queensland. Figured by Owen, op. cit. pi. cxiii. figs. 1-3. 



Presented by Dr. George Bennett, 1873.
