Notes and Exhibits. 



Mr. North exhibited skins, nests and eggs of Acanthiza etvingi, Gould, 

 and Acanthornis magna ^ Gould, from Tasmania. They were received by the 

 Trustees of the Australian Museum, in March, 1902, the birds being sent 

 in the flesh. The nest of Acanthiza ewingi is a neat domed-shaped structure, 

 with a rounded entrance in the side. Externally it is formed of thin strips 

 of bark and bark-fibre, and thickly coated with bright green moss, the inside 

 being lined with the rich brown downy covering of freshly budded fern-fronds 

 and a thick layer of feathers of the yellow-bellied Parrakeet. It measures 

 externally 41/2 inches in height, 3 inches in diameter, and across the entrance 

 1^4 inches. The eggs, three in number, are rounded-ovals in form, pure 

 white, with distinct zones on the larger ends formed of small confluent spots, 

 flecks and streaks of difi'erent shades of purplish-red. Length (A) 0,68X0j52 

 inch; (B) 0,67X0,52; (C) 0,69X0,5. Two eggs in the collection of Mr. 

 Charles French, Junr., .taken prior to 1899 by Mr. G. F. Hinsby on 

 Mount Wellington, near Hobart, measure alike, 0,67X0,49 inch. 



At the next Meeting of the Society, to be held on Wednesday, 

 27th April, 1904, the following communications will be made: — 1) De- 

 scriptions of new Species of Australian Coleoptera. Part VIL By Arthur 

 M. Lea, F.E.S. — 2) Contributions to a Knowledge of Australian Entozoa. 

 No. in. On some Species of Holostomidae. By S. J. Johnston, B.A., 

 B.Sc. — 3) Australian Fungi, new or unrecorded. Decades VII.-VIII. By 

 D. McAlpine, Corresponding Member.

Challenger. — April 27. — Sir John Murray in the chair. — Prof. 

 Minchin exhibited specimens of the new Sporozoan, Lymphocystis johnstoni. 

 — Mr. E. T. Browne showed Medusae from Valencia. — Dr. G. H. Fow- 

 ler explained some graphic diagrams of the distribution of Biscayan Chaeto- 

 gnatha, and announced that he had detected Krohnia hamata among speci- 

 mens obtained at the Falkland Islands by Mr. Vallentin within six fathoms 

 of the surface. — Mr. V, H. Blackman read a paper on ''The Metabolism 

 of the Ocean'', dealing with the close analogy between the circulation of 

 nitrogen on land and that in the sea. This was followed by an interesting 

 discussion. — Mr. G. P. Far ran described the Copepods of the North-East 

 Atlantic slope. Of these rather less than half present a wide and often tro- 

 pical distribution, occurring also in the Pacific or Indian Ocean. The re- 

 mainder are only known as Atlantic or Atlanto-Mediterranean species, many 

 being bottom-haunting forms, the recorded range of which is likely to be 

 extended. About 12 per cent, of the total Copepod fauna extends north to 

 the Arctic regions.
