Tepper, the fossiliferous rocks referred to by that gentleman 

 in his paper published in last year's Transactions. He was 

 happy to be able to confirm the principal statements made by 

 Mr. Tepper. He also exhibited some fossils collected by 

 himself from the Lower Silurian rocks, amongst them being a 

 well-preserved head of a trilobite, which showed no trace of 

 eyes. 



Professor Tate exhibited specimens of thi'ee species of the 

 pelagic mollusc, Ianthina, which he had received from King 

 George's Sound, through the kindness of Professor Davidson. 

 The shells were in a fine state of preservation, and had 

 evidently been taken alive, as the wet sand in which they were 

 packed had been stained a rich violet hue by the colouring 

 matter exuded from the animal. 



Mr. T. D. Smeaton exhibited a number of small black 

 insects which he had received from Jamestown. He explained 

 that they were frequently found in cart-ruts. The body of 

 these insects he had found to be oval, while they were furnished 

 with antennae. The eye was depressed and compound, and the 

 body had a springing motion, but nevertheless it was probable 

 that the animal was not a jPodurus, as it had no spring-tail.

NOTES AND EXHIBITS. 



Professor Tate read portions of a letter from Baron P. von 

 Mueller in reference to the indigenous plants of South Aus- 

 tralia, and he advised that the Society do solicit Baron P. von 

 Mueller to prepare a revised list, giving more detailed infor- 

 mation, especially in regard to localities, an item in which the 

 " Plora Australiensis " was deficient. 



Mr. Molineux exhibited specimens of Apliropliora spumaria, 

 found abundantly on all kinds of plants in his garden at Kent 

 Town. The perfect insect has pure white chalky-looking 

 wingcases ; the larvae, in its first stage, is enveloped in the 

 characteristic frothy liquid, but afterwards it became covered 

 with a downy material like that of the "mealy-bug." 



Mr. Thos. D. Smeaton exhibited a portfolio containing a 

 large number of plants collected upon the River Darling.
