10 
discoveries made at Clifton Colliery, by Mr. Simpson, I think 
more notice should be taken of them than the usual notice 
given in the local papers, as I consider it is the duty of a 
scientific society to let nothing pass without description ; and I 
am sure the donor cannot think his discovery is valued, if no 
further notice is taken of it. 
To return to the consideration of the localities in which 
fossil remains are to be found, I think I can put the boundaries 
pretty well from. G-owrie to Spring Creek, Clifton (none are 
recorded as being found in Dalrymple Creek, on the Warwick 
side of Spring Creek) ; thence to the Condamine River, and along 
its eastern bank as far as Chinchilla (where I have seen speci- 
mens embedded in the rock). These boundaries include Eton 
Yale, Clifton, Pilton, Glowrie, Yandilla, Cecil Plains, St. Ruth, 
Jimbour, and Warra Warra, Jimbour Station being the northern 
boundary ; so the area to be searched is limited, and a small sum, 
judiciously expended after a heavy flood, may yield some very 
valuable specimens. 
I think I have now treated as much on this subject as my 
limited experience will allow, being only an amateur ; and if it 
had not been for my father (Dr. George Bennett, F.L.S., of 
Sydney) keeping me posted up in all the latest discoveries, I 
could not have attempted it at all. I am also indebted to him 
for making the study of these marsupials a pleasure to me, by 
his valuable notes on my specimens, which at first I only under- 
took as a duty ; but with such encouragement it has grown into 
an ambition to further the advancement of these enquiries. To 
Professor Owen I am also indebted for sending me his papers on 
the fossil mammals of Australia, as they have been read before 
the Royal Society of England. 
If the foregoing remarks will only induce some energy to 
be thrown into this particular branch of Science, my labors in 
this short paper will be well rewarded.
