A collection of upwards of 30 rnariue and fresh water shells, 

 comprising good specimens of the following genera — Cyprcea, Hip- 

 pojnis, Pinna, Pi/rula, Natica, Ovula, Conus, Mitra, Cyclostoma, and 

 Ampularia, from Mr. John Abbott. 



Two fragments of copper ore from Sir Henry Atkinson. 



Seventy copper coins of ancient Kome, modern Italy, and other 

 countries, from Mr. William Abbott. 



A mass of siliceous matter, replete with impressions of Ferns 

 {Pecopteris Oclontopteroides, as figured by Stizeleclii), found at Broad 

 Marsh, from Mr. Walch. 



The Secretary reported two cases of plants, forwarded from 

 the Society's Gardens, per Munford, to New Zealand, and one case 

 forwarded per Emma, to Sydney, containing plants and scions of 

 fruit trees, varieties of willows, strawberries, &c. &c., for Mr. 

 Bowman, of Camden. 



The Secretary placed upon the table two marine parasitical Isopo- 

 dous Crustaceans (OniscidesP — Latreille), obtained from the rock- 

 cod and gurnard here ; also an imperfect shell of Nautilus pomjnlius, 

 thrown up by the sea on the east coast of Van Diemen's Land — and it 

 was remarked, that as a perfect specimen of the same was obtained at 

 Flinders' Island some years ago amongst a vast number of shells of 

 the paper nautilus {Argonautus Argo), cast ashore there at same 

 time, it may fairly be set down as an occasional inhabitant of 

 these seas. 



Mr. Milligan also mentioned having recently discovered, in a 

 ravine upon the east coast of the colony, an elegant-looking shrub, 

 ranging from six to twelve feet in height, clothed with long digitate 

 leaves, set opposite, and drooping at their extremities, and having its 

 young shoots more or less hollow and filled with pith, like those of 

 the Sambucus. The shrub exhibited neither flower nor fruit. It will, 

 probably, be referred to the Umbellales of Lindley, and to the order 

 Araliacece, a dwarfish member of which (Panax Gunnii) Mr. Milligan 

 discovered in 1842 in the dense dark forests near the Franklin River. 

 This new shrub promises to become an acquisition to our arboretums 

 and pleasure-grounds, and ought to be introduced. 



Thomas Dobson, Esq., of the High School, read a paper upon three 

 varieties or sub-species of Psijlla, which he terms Psylla Eucalypti, — 

 insects which, in the larva state, have the faculty of elaborating from 

 the juices of the gum-leaves on which they live a glutinous and sac- 

 charine fluid, whereof they construct for themselves little conical
