NOTES AND EXHIBITS. 



Mr. Hedle}' exhibited a specimen of fully developed Gundlacliia 

 recently taken by Mr. H. Leighton Kesteven from a pool in the 

 Botanical Gardens, Sydney. This is the second instance of its 

 occurrence in Australia, and the first in New South Wales. The 

 o-enus has been treated of at some length in Vol. viii. (2nd Series) 

 of the Society's Proceedings. Possibly no real Ancylus exists in 

 Australia, and all those hitherto reported will ultimately be 

 shown to assume occasionally and at rare intervals the Gundlacliia 

 form. Also photographs forwarded by Mr. Alex. Morton, 

 Curator of the Tasmanian Museum, of a gigantic fish-hook almost 

 identical with that described in the last Volume of the Proceedings. 

 The original was collected near Membare in British New Guinea 

 ])y the surgeon of H.M.S. Wallaroo. 



Mr. Froggatt exhibited a series of fruit-flies (Tephritis tryoui, 

 Froggatt, the Queensland Fruit-fly, Salterophora capitata, Wied., 

 the European Fruit-fly, and Trjjpeta sp.), all of which had been 

 Ijred out of fruit obtained in the neighbourhood of Sydney. Also 

 samples of apple showing how the San Jose Scale (Asjjidiofus 

 p)erniciosi(s, Comst.) discolours the fruit which it attacks. 



Mr. Turner exhibited specimens of three grasses, Aristida 

 leptopoda, Benth., (from Liverpool Plains, N.S.W.), A. hehriana, 

 F.V.M., and A. ramosa, R.Br., (from Narromine, New South Wales), 

 the inflorescences of which were afiiected with parasitic fungi. 

 The first and second of these had not previously been observed in 

 this condition. Some pastoralists are of opinion that these 

 fungoid growths are the cause of certain diseases of stock. A Iso 

 a specimen of Atriplex angulata, Benth., (from Mount Brown, 

 N.S.W.), infested with a species of dodder (Ciiscufa tasmcmica, 

 Engl.), the first time that this pest had been noted on an 

 Australian salt-bush. C. tasmcmica was not known to be a New
