such a manner that the wind always tends to force the bird ii^pwards, 

 and that the bird never sinks at all. Of course the bird is carried 

 faster along with the wind the quicker it rises. 



NOTES AND EXHIBITS. 



Mr. C. S. Wilkinson exhibited some Fossil Bones which had 

 been recently obtained from the coral sand rock on Lord Howe 

 Island. Amongst them was an almost complete skull somewhat 

 resembling that of the Horned Lizard Megalania prisca, from the 

 Pleistocene deposits on the Darling Downs, Queensland. 



Mr. Wilkinson also exhibited specimens of Shells of oysters 

 found in the beds of clay and sand at a depth of 40 feet below 

 the surface, in sinking the new shaft of the Bullock Island and 

 Wickham Coal Company near Newcastle. Mr. Brazier identified 

 this oyster, which must have been 12 inches in length, as a large 

 form of the Ostrcea edulis. 



Dr. J. C. Cox exhibited other specimens of the Ostrcea edulis 

 from Port Jackson, found firmly attached to a bottle. He pointed 

 out the great difference between this oyster, which will not keep 

 for more than a day, and the Englisli native oyster, and suggested 

 that they are of separate species. Mr. E. P. Ramsay mentioned 

 that the same oyster in South Australia keeps well for many days, 

 and was of opinion that they were the same as the 0. edulis of 

 England. 



Mr. Ptamsay exhibited a Fossil phalanx of Palmorchestes, from 

 Wellington Caves, from the size of which he calculated tliat the 

 animal must have stood about 15 feet high. Also some Devonian 

 shells and corals from the same district, in which the lime had 

 been replaced by silica, and which had been cleared from the 

 matrix by the application of muriatic acid.
