Fossils from the Gulf Watershed. 
The bones from the Leichhardt River lately collected under 
the auspices of the Department of Agriculture by Mr. Stock Inspector 
Buhot, and referred to me for examination, have not the good fortune 
to increase to any notable extent our knowledge of the extinct fauna 
represented by them. The animals which once owned them were 
few both in number and kind compared with the wealth of diverse 
forms which in their day of life the country was nurturing. 
Moreover, the relics are almost invariably mere fragments, greater 
or less in size, and sometimes also much waterworn — conditions easily 
acquired during a rough passage down the bed of a river, but 
naturally rendering them difficult of study. 
Of the 43 which have escaped utter destruction and retain 
features helpful to recognition, eight were of reptilian origin. The 
remainder were derived from marsupial mammals and mostly from 
those giants of the Order whose bones were massive enough to 
partially resist the shocks and attrition to which they have been 
subjected. 
Most of the fossils were, by the foresight of Mr. Buhot, marked 
with distinguishing numbers, each indicating the precise locality of 
collection. Numbers i to 6 and No. 34 are from u the top crossing" 
of the river, 7 miles below Augustus Station ; No. 7 to 16 from 
Floraville Post Office ; Nos. 17 to 46 (No. 34 excepted) from the 
river bed and conglomerate on the banks at Floraville Crossing. 
The retention of these numbers may possibly be of use should further 
investigation on the spot be undertaken. 
The contents of the collection are specified below under the 
name of the animal to which each bone is thought, with certitude 
more or less perfect, to belong. Until bones of most of the very 
numerous species now extinct occur in organic connection with skull 
or teeth, or in company with them so close that no doubt can remain 
about their specific identity, their ascription to one or other species 
or even genus is entirely a matter of opinion liable at any time to be 
proved erroneous by fresh discovery. 
MAMMALIA— MARSUPIALIA. 
FAMILY NOTOTHERIID^E. 
DlPROTODON AUSTRALIS, Owen. 
The unequalled size of bones of the Greater Diprotodon renders 
them easy of recognition : — 
Right ramus of a mandible, with the symphysis and roots of 
the incisor tusks and with the last three molars (the 
hinder lobe of No. 3 excepted) in place ; the ascending 
process wanting. — No. 31.
