NOTES AND EXHIBITS. 127 



Mr. John Mitchell contributed a " Note on the discovery of a 

 bone-deposit and on some of the fossils found therein " : — 



In December last Mr. G. K. Horan brought under my notice 

 the discovery of a bone-deposit on the Terrible Vale Run, the 

 property of F. G. Taylor, Esq., in the parish and county of Sandon, 

 about two miles from the Kentucky Railway Station. Both Mr. 

 Taylor and Mr. Horan have taken great interest in the discovery, 

 and have devoted some considerable time and labour to its explora- 

 tion. Mr. Horan has sent me several parcels of the teeth found in 

 the deposit, with samples of the drift in which they are enclosed. 

 The bulk of these teeth prove to have belonged to members of 

 the Macro2)odidce and probably to existing types. Some of the 

 molars are large, yet not larger than those possessed by the largest 

 living specimens of the genus Macrojnis. One lai-ge upper incisor, 

 for the determination of which I am indebted to the assistance of 

 Mr. Etheridge, palaeontologist, and Mr. Barnes, articulator, to the 

 Australian Museum, indicates by its massive proportions a species 

 larger than existing forms. By the courtesy of the gentlemen 

 just mentioned I was enabled to compare this incisor with the 

 large incisors of others of the Macrojyodidce from Wellington 

 Caves, and I found it agreed with them fully, though not so large 

 as the largest incisors from that locality. 



Perhaps the most interesting are two which appear to be very 

 small carnassial teeth of Thylacoleo, the presence of which would 

 indicate a geological age corresponding with that of the older bone- 

 deposits of Wellington and Goodradigbee Caves, and probably the 

 Myall Creek bone-beds (Records Geological Survey of N.S.W. 

 Vol. i. part 2). 



From information and specimens supplied by Mr. Horan, I am 

 able to give the following particulars concerning the occurrence of 

 the deposit and of the geological features of the neighbourhood. 

 The bones are exposed in a newly-formed water-course, and are 

 covered by ten feet of alluvium chiefly formed of granite detritus. 

 The bones are very tender ; their interiors have decomposed and 

 become replaced with sediment, and consequently break very 

 easily ; even the teeth in many cases have lost all their original
