Stlienurus, are merged in Macropm. The greater portion of this section of the present 
work was compiled before the appearance of the British Museum Catalogue, and to this 
the reader is referred for the unravelling of the intricate synonymy attached to these 
fossils. The fossil Macropodidae have recently been re-studied by Mr. De Vis in the 
light thrown on them by the very large Collection in the Queensland Museum, but the 
results await publication.

Ols. The former existence of this species was determined by Prof. Owen upon 
the evidence afforded by portions of several jaws and a humerus, &e., obtained from the 
Wellington Valley Caves and the Queensland Preshwater deposits. The remains 
exceeded in size those of the living Jilaoropm major. The humerus exceeds in length 
that of the last-named species as much as that of Fliascolagus falls short of it, and the 
strength or thickness of this bone is greater than in the latter. 
In addition to these remains, a very fine skull, more or less complete, was 
obtained by Mr. W. P. Tooth, .Tunr., at King’s Creek, Darling Downs, the measurements 
of which, as compared with a skull of JHacropus major, are given by Sir E. Owen.* 
JUacropus titan is closely allied to the living iff. giganteus, “ but is distinguished by 
its superior size, and the very general occurrence of one or more vertical grooves on the 
hinder surfaces of the lower true molars ; it is, however, probable that the two forms 
pass imperceptibly into one another.”
