Prof. Tar, F.L.S. (Vice-President), in the chair. 
Exuisits.—A. Zierz (Assistant Director of the Museum) 
exhibited from Myponga, a piece of micaceous sandstone in form re- 
semblinga Maori flax-beater. [twas considered to have been formed 
by natural causes. J. G. O. Tepper, F.L.S., showed a collection of 
plants from Yilgarn, W.A., collected by Miss Rogers; also, a 
species of gregarious caterpillar spinning a common nest. They 
appeared to be nocturnal in their habits. The nests infested the 
Acacia salicina, growing between Moonta and Wallaroo, and were 
forwarded by Mr. Styles in October. The following December 
the cocoons were spun in the nest, and in February the zmago 
emerged, and at once laid eggs, which were covered with the 
scales of the moth. Prof. Tats, F.L.S., laid on the table 
specimens of Tasmanian gems; a tooth of Zeuglodon from the 
Eocene of Tasmania, and a similitude of a shoe-last in ironstone.

Exutsits.—Prof. Tarr, F.G.S., exhibited the fossil cast of a 
gigantic tooth of Carcharodon megalodon found in the Eocene 
beds at Hamilton, Victoria. It measured five inches in length 
and four inches in breadth. Applying to this tooth the data 
arrived at by Dr. Bowerbank in 1852 from an inyestigation of 
the teeth of a specimen of Carcharias glaucus caught in 
Australian waters during the voyage of H.M.S. “Beagle,” namely, 
_ that 102 times the length gave the vertical gape of jaw 8+ times, 
the horizontal gape, and 1694 times the length of the animal. 
The owner of the tooth exhibited must have had a vertical gape 
of jaw of 51 ins.; a horizontal gape of 41 ins.; and have 
measured 70 ft. 6 ins. in length. A. Zinrz (Assistant Director 
of the Museum) showed stuffed specimens of Cheropus, or the 
pig-footed bandicoot, and compared them with specimens of 
Peragalea lagotis and Perameles obesula, the common bandicoot.

preefolia.
