 elegatis, Wall., sometimes mistaken for Aristolochia. Mr. Maiden 

 also took the opportunity of mentioning that the new orchid- 

 house at the Botanical Gardens was on the point of completion, 

 and that he would be glad to receive specimens of Australian 

 orchids with a view to a more systematic cultivation of this 

 section of the flora. 



Mr. Etheridge exhibited a collection of spears, throwing-cords, 

 and photographs in illustration of his paper. 



Mr. Palmer exhibited portion of the trunk of a Eucalypt and 

 a quantity of chips torn therefrom, to show to what purpose the 

 Black Cockatoos can use their enormously powerful mandibles 

 when engaged in the search for boring longicorn larvae. The 

 stem of the tree exhibited had l^een ripped up and almost severed, 

 and was one of a number more or less similarly treated at 

 Lawson, Blue Mountains. 



The President exhibited a specimen of the Sydney Bush-Rat 

 (Mus arboricola, W. S. Macleay, or M. rattus according to Mr. 

 Oldfield Thomas) from a garden at Double Bay, together with the 

 gnawed branches of a Bougainvillea, which was threatened witli 

 destruction. He also remarked, in reference to Mr. Palmers 

 exhibit, that in his grounds at Springwood the Black Cockatoos 

 had succeeded in ring-barking some trees of one of the Manna 

 Gums one foot in diameter, in pursuit of boring grubs.
