NOTES AND EXHIBITS. 



The CuEATOR OF THE ADELAIDE MusEUii, OU behalf of the 

 Governors of the 8. A. Institute, showed specimens of jawbone 

 of Diprotodon cmstralis, containing molar teeth, and two upper 

 incisors, lately found and presented to the Museum by Mr. W. 

 jN". Petliic, of the Suryeyor-General's Department. These were 

 found near Millicent (South-East District) at a depth of six 

 feet below the surface, embedded in peat mixed with shells ; 

 also, some specimens, presented by Mr. M. F. AVeidenbach, of 

 the Amphioxus or Lancelot, from the Mediterranean. 



Dr. Gaze laid on the table a specimen of a legless lizard, 

 which had been found on the sandhills at Glenelg. 



Professor Tate exhibited a very fine adult example of Semi- 

 cassis pcniciruc/is, collected by the Eev. C. G. Taplin on the 

 coast near Lake Hamilton. 



Professor Tate exhibited a portion of a large collection of 

 New Zealand fossils presented to him by Dr. Hector, Director 

 of the Geological Survey of Xew Zealand. The specimens 

 exhibited were selected chiefly to indicate the close similarity 

 between the Older Tertiary species of South Australia and those 

 of Xew Zealand ; several species are common to the two 

 regions, and by them the exhibitor correlated the Eiver Murray 

 beds and the polyzoal sands of Aldinga Bay with the Trellis- 

 sick group in New Zealand. The latter Dr. Hector assigns to 

 the Upper Eocene ; whilst Professor Tate, in his " Outlines of 

 South Australian Geology," places their probable equivalents 

 in South Australia in the Oligoceue period, rather in confor- 

 mity with the A^ictorian classification than as a fixed opinion of 

 his own. The inferior beds of the Aldinga section he has 

 always maintained to belong to the Eocene period. Xeverthe- 

 less the generalizations arrived at by independent observers 

 touching the period of deposition of the Older Tertiaries in 

 South Australia, Victoria, Tasmania, and Xew Zealand do no^ 

 materially differ one from another.
