EXHIBITS. 
1. Mr. EK. F. PITTMAN sent a new geological map of New 
South Wales which had just been prepared under his super- 
vision. 
2. Mr. G. P. DARNELL SMITH exhibited a so-called bulb 
of the pest Prickly Pear, Opuntia inermis, and pointed out 
that in any device for destroying this plant it would be 
necessary to include a means of destroying this bulb. 
3. Mr. SmirH exhibited the seed case of the Wooden Pear, 
Xylomelum pyriforme, which on being gathered had been 
immediately bound with copper wire. Such is the force 
with which the seed case gradually opens that the copper 
wire, if not broken, cuts into the seed case, which is of 
extraordinary hardness. ; 
4, Specimens of a siliceous sponge Purisiphonia Clarkei, 
Bowerbank, from the Lower Cretaceous of Wollumbilla, 
Queensland, were exhibited by Mr. W. S. Dun.
