NOTES AND EXHIBITS. 



Mr. Brazier exhibited a handsome specimen of fan-shaped 

 Retepora iilicenicea, Busk, which had been washed ashore after a 

 gale at the mouth of the Bellinger Kiver. He also exhibited a 

 specimen of Meretrix lusoria, Lam., used by the natives of Ysabel 

 Island, Solomon Group, for extracting hairs from the face and body. 



Mr. Deane exhibited two eggs, almost quite black, laid by a 

 common duck. He stated that after several eggs were laid, the 

 colour for a time became a little lighter, and the laying ceased, but 

 on recommencing laying the eggs were as black as ever. 



Mr. Maiden exhibited a fine specimen of shell-conglomerate 

 from high-water mark at Manly Beach. 



Dr. Katz exhibited pure cultivations of the Bacteria mentioned 

 in his paper, and Japanese Isinglass of good quality. He also 

 exhibited several geological hammers, of best cast-steel, from a 

 Westphalian manufactory. 



Mr. Smithurst exhibited a fine slab of shale crowded with 

 impressions of ferns, from the Upper Coal Measures at Wallsend; 

 also a hollow ironstone nodule from the same district, and a 

 specimen of fossil Polyzoa from Heywood, Victoria. 



Dr. Cox exhibited two living specimens of Helix (Rhagada) 

 Kooringensis, sent to him by post from about 30 miles N.E. from 

 the Burra Burra Copper Mines, S.A. This peculiar species was 

 described by Angas (P.Z.S. 1877, p. 33), and is closely allied to 

 H. tiilveri, Angas, differing in a very striking manner from any of 

 the other numerous Helices found in Australia. Dr. Cox also 

 shewed an interesting old work of date 1777 entitled " Catalogue 

 of the different specimens of cloth collected in the three voyages 

 of Captain Cook to the S. Hemisphere, <fcc, illustrated with 

 samples of the cloth."
