264 MOLLUSCA 



Family Athoracophorid^ 



Aneitea grajfd, Humbert 



"This slug, a native of Queensland and New South Wales, was 

 found at Port Chalmers by Dr C. Chilton, and near Collingwood 

 by Mr J. Dalli." 



Order PSEUDOLAMELLIBRANCHIATA 



Family Ostreid^ 



Ostrea edulis, Linn. 



In 1868 Mr W. C. Young shipped a quantity of oysters by the 

 'Celestial Queen' from London to the Otago Society. Only two 

 arrived alive in Dunedin : " These have been deposited on an artificial 

 oyster bed at Portobello, where it is to be hoped they will do well." 

 Great was the faith of these early pioneers in acclimatisation work. 

 According to a letter from Mr Frank Buckland these oysters were 

 from the River Roach in Essex, and were presented by Mr F. Wiseman 

 of Paglesham. Mr Buckland evidently had not sampled the oysters 

 of Foveaux Strait for he adds: "Oysters are found naturally in New 

 Zealand, but if the culture of a better class could be instituted there 

 is a chance of an additional source of food being supplied to the 

 colony." 



^ In Mr Musson's list of introduced MoUusca (1890) he gives Zotdtes nitidus, 

 Miiller, as found by himself at " Lake St John, Auckland ; a dozen specimens under 

 logs." Mr Suter informs me that the species was the indigenous Fretum novarce, 

 Pfeiffer. 



Neritina fluviatilis, Linn., was reported from the Waikare River by Mr T. Kirk, 

 and identified by Mr Musson in 1890. Mr Suter doubts the accuracy of the locality, 

 and seems to think the specimens were taken — by mistake — ^from the collections 

 in the Dominion Museum.
