NOTES AXD EXHIBITS. 



Mr. Brazier, who had previously recorded the occurrence of 

 pearls in Trigonia Lamarcki, and Chione callophylla, Phillipi, 

 exhibited a double white pearl taken from Tapes ttorgida, Lam., 

 at Goonamatta Bay, Port Hacking; a small black pearl taken 

 from Oslrea cucullata, Born, found at the Bottle and Glass 

 Rocks, Vaucluse, Port Jackson; three specimens taken from 

 Ostrea subtrigona, Sowb., (sometimes called drift oysters by the 

 oyster dealers, as they sometiines are when heavy freshes come 

 down the rivers and dislodge them from the shallow beds, but 

 it is a mere variety of 0. cucullata, Born.) Mr. Brazier stated 

 also that a large quantity of Ostrea cucullata, taken off the rocks 

 on the sea coast and placed in one of our southern lakes, had 

 developed into the fine large variety 0. suhtrigona. 



Mr. Brazier also exhibited a pale brownish sinistral variety of 

 the introduced Helix similaris, Per., found among some hundred 

 specimens of the dextral form in Mi-. J. A. Thorpe's garden at 

 Paddington; white sinistral varieties of Marginella De Burglda^., 

 A. Ad., and Marginella capensis, Dunker; a sinistral variety of 

 Marginella apicina, Menke, from the Bahamas, West Indies; and 

 a sinistral variety of Columbella ( Atilia) filosa, Angas, from the 

 Sow and Pigs Reefs, Port Jackson, 4 fathoms. 



Also, examples of IStilifer tumida, Petterd, found by Mr. T. 

 P. Hitchcock in beach shingle, half a mile north of Wollongong, 

 in January, 1892. Originally described from North Tasmania, 

 the same species has been found by Mrs. Kenyon at Flinders, 

 Victoria, so that it has a wide range along the South-East Coast 

 of Australia. 



Mr. Fred Turner exhibited plants of Tracliymene incisa, 

 Rudge, forwarded to him by Mr. McKern, who reports that 

 children eat quantities of the roots of this plant, and that they 

 call them "wild carrots." 



Also fresh branches of the Japanese Elm (Planeria acuminata, 

 Michx.), of the Mexican Soldier Bush (Inga jndcherrima, Cerv.)
