NOTES AND EXHIBITS. 



Mr. Douglas-Ogilby exhibited the tongue of a specimen of 

 Lates calcarifer shewing that it is partially covered with patches of 

 grannlose teeth, as previously pointed out by Dr. Bleeker and the 

 Hon. W. Macleay, but denied by European Naturalists ; the 

 lingual teeth are similar in form and composition to those of the 

 other tooth-bearing bones, and the term villiform cannot be applied 

 to them. 



Mr. Macleay exhibited from his own collection eighty-five species 

 of the insects described in his paper on the genus Liparetrus. 



Dr. Ramsay exhibited photographs of the skeleton of Megaceros 

 Hibernicus, the Irish Elk, taken from a very fine specimen 

 recently received by the Australian Museum ; Tasmanian stone 

 axes — all pebbles rudely chipped and without definite shape ; and 

 a double-headed axe from the Admiralty Islands. 



Mr. Brazier exhibited a large series of shells of the genus Triton 

 comprising examples of the following species ; Triton Tritonis, 

 Linn., from the Solomon Islands ; T. nodiferus, Lam., from 

 Marseilles, France ; and the variety T. australis from Berry's Bay, 

 and Bottle and Glass Rocks, Port Jackson, and from Port 

 Stephens. The type from the Mediterranean is a thick and heavy 

 shell, whereas the Australian variety is much thinner. The latter 

 extends also to Japan. 



Mr. Masters exhibited a living specimen of Phyllurus inermis, 

 the " rock scorpion " of qnarrymen — caught at Elizabeth Bay, a 

 lizard which is now becoming scarce about Sydney ; and a 

 specimen of each sex of a N. American butterfly — Papilio 

 androgens — together with a third specimen shewing the charac- 

 teristic form and colour of both sexes one on the right, the other 

 on the left half of the insect.
