Introductory Note 
4 ^ 
Incidentally when dealing with the humeri of the Xototheria. 1 found that 
the extinct King Island wombat had an exceptionally long and narrow humerus, 
quite unlike that of any existing species. A similar type of humerus recently- 
sent to the Museum by Mr. E. C. Clarke, of Mole Creek. Tasmania, closely 
simulates this upper arm bone of the extinct King Island animal. From the 
Limestone Caves, that furnished the latter, Mr. Clarke recovered a single 
humerus that agrees very closely with the same bone in the skeleton of the 
hairy-nosed wombat of South Australia. 
As the narrow wombat humeri agree in general contour with those of 
Xotothcrium tasmanicum, and the humeri of the living Tasmanian, mainland, 
and Flinders Island wombats reproduce characters nearer to those of the so- 
called humerus of Xototherium mitchelli, i have decided to publish figures of 
these several bones. 
As fully discussed in my Memoir upon Xototherium tasmanicum, issued b\ 
the Geological Survey of Tasmania, the humerus relegated to Xototherium 
mitchelli is open to question. 
These comparative notes, however, tend to prove that future discoveries 
may show, that a long narrow type of humerus, and a short wide one, obtained 
among the extinct Xototheria, as it does among the more recent wombats.
