hibited specimens of Tettix australis, Walker, a smal grasshopper whicli h.e 

 had found in some numbers in shallow fresh water pools on the banks of the 

 River Nepean, some 15 miles above Penrith (N.S.W.), in the month of 

 September last. Mr. OUiff said that specimens were first observed clinging 

 to the leaves of a water plant on the surface of the water, but afterwards 

 many others were found both by Mr. Ogilby and himself on the stems of the 

 plants 8 or 10 inches below the surface. When disturbed they swam to the 

 bottom of their own accord. Mr. McLachlan, F.R.S., who kindly identified 

 the species,' writes that the Tettix of Europe usually frequent dry sandy 

 places. — He also exhibited male and female specimens of a pelagic Hemi- 

 pteron [Halohates Wüllirstorß, Frauenf.) which had been captured by Mr. 

 Wagstaif, in a towing net ofi" the West Coast of Australia. The species is of 

 very wide range and has been observed near Norfolk Island and New Guinea, 

 but has not hitherto been recorded from waters west of mainland of Austra- 

 lia, — Mr. Masters exhibited a large Hive of Bees entirely destroyed by 

 Achrea grisella, a Tinea introduced from Europe. Also a seed vessel of Trapa 

 hicornis , a Chinese species , imported into the country as an edible, and 

 known as the Buffalo Nut. — Mr. C. S. Wilkinson exhibited some fossil 

 Turtle eggs embedded in coralsand rock, from Lord Howe Island. In the same 

 rock are found numerous bones of Turtles, associated with bones of the extinct 

 HornedLizard, Megalania,oî which two skulls have beenfound. — Mr. Wil- 

 kin son also exhibited two specimens of Trochus imperialis from New Zealand. 

 — Mr. Fletcher exhibited a specimen of a female of Antechinus ßavipes, one of 

 the smaller Dasyuridae, having nine mammary foetuses on the teats in the 

 shallow pouch. Mr. Krefft (Trans. Philos. Soc. of N.S.W. , 1862—65 p. 10) 

 has recorded the occurrence of the same number in this species, and on one 

 occasion he met with ten young ones. The specimen exhibited was kindly 

 sent by J. D. Cox, Esq., of Cullenbone near Mudgee, a Member of the So- 

 ciety. Mr. Fletcher also exhibited three blastodermic vesicles of Kangaroos, 

 [Halmaturus dorsalis and Osphranter robustus) the largest of which was about 

 the size of a large pea, and shewed a pear-shaped embryonic area. All the 

 vesicles were quite unattached to the uteri , the cavities of which exactly 

 corresponded to the size and shape of the vesicles. Also a uterine foetus of 

 Osphranter robustus of nearly the full period, about an inch long, with the 

 foetal membranes attached.
