NOTES AND EXHIBITS. 351 



Similar specimens, lent by Mr. G. W. Card, A.R.S.M., from the 

 Geological Survey Museum, Mines Dept., and collected at Port 

 Hacking, were also exhibited. The exhibits were apparently of 

 a similar nature to the tubular structures noticed in dune sands 

 in other parts of Australia, as described in detail by Mr. T. S. 

 Hall, M.A., in a paper "On certain Incrustations on Wood in 

 Dune Sand."* 



Mr. Froggatt showed specimens of the Vine Moth, Phalcenoldes 

 (Agarista) glycine Lewin; and also of a parasite, the Red-legged 

 Ichneumon, Pimpla iiitricatoria Fabr. The pupse of the Moth 

 were collected in an orchard at Canley Yale. Pupation ordinarily 

 takes place in the ground; but in this particular instance the 

 chrysalides were developed among leaves pressed against the 

 stakes when the vines were tied up; and scarcely a single one 

 had escaped the attention of the parasite. 



On behalf of the author, Mr. Hedley exhibited the types of 

 the deep-water Crustacea described in Mr. Grant's paper. 



Mr. Hedley also exhibited, on behalf of Mr. Bassett Hull, 

 good examples of Pearl Oyster Spat (probably Meleagrina 

 vulgaris Schumacher) found on pieces of pumice washed up on 

 the beaches north of Sydney, between 7th February and 31st 

 March, 1904. At the end of 1903 a submarine disturbance 

 occurred at Tanna, New Hebrides. On the 8th January, 1904, 

 the schooner ' Enterprise ' sailed for two days through floating 

 pumice some 200 miles west of the Banks Islands. From Feb- 

 ruary to March, 1904, many tons of pumice were washed ashore 

 on the beaches of Deewhy, Curl Curl, Freshwater and Manly. 

 Many pieces bore pearl oyster spat from ^ of an inch to IJ^ inch 

 in diameter. These were all alive, and even after exposure to 

 rain and sun for 72 hours showed signs of life. From one piece 

 of pumice weighing about 20 oz. no less than 40 spat were taken. 



Mr. R. T. Baker exhibited specimens of a nut (sic) found a 

 few inches in the ground, and which are scratched up, and the
