Ordinary Meeting, June 8, 1916. 



The President (J. C. Verco > M.D., F.R.C.S.) in the 

 chair. 



Nomination. — Lionel B. Bull, pathologist and bacteri- 

 ologist, was nominated as Fellow. 



Election. — W. Champion Hackett, seedsman, was 

 elected a Fellow. 



Exhibits. — Mr. E. P. Waite exhibited a common 

 Adelaide flounder, which was ambi-coloured, the lower side 

 the same colour as the upper. The prolonged dorsal fin had 

 not, as usual, joined the snout, an apparent incision being 

 thus left between the fin and the skull, so that the fish could 

 see on its under-side. Also a somewhat rare pelagic prawn 

 from the mouth of the Gawler River. Captain S. A. White 

 showed some shells (Turbo stamineus), weighing from 8 oz. to 

 10 oz. each (when alive), and a Pacific Gull ( Gabianus pacific 

 cus), which was stated to carry these shells aloft and drop 

 them on the rocks to break them. Dr. Morgan had sug- 

 gested that, as the gull could only carry them in its beak, its 

 balance in flight would be disturbed by so doing, and that 

 this work was really done by the Osprey (Pandion haliaetus 

 cristatus), which had talons suitable for the purpose. The 

 balance of opinion amongst the Fellows present was in favour 

 of the gull, but further observation was deemed necessary. 

 He also showed two immature skins of the Mutton Bird 

 (Neonectris tenuirostris bt^evicaudus), showing the growth of 

 the down on the tip of the feathers, so that when the down 

 came off the bird was fully fledged. Also a new species of 

 Scrub Wren, which he was describing as Sericornis longirostris 

 wyldei (Coorong Scrub Wren). Mr. A. M. Lea showed a 

 large mot ; h (Trictena labyrinthica), which laid over 31,000 

 eggs in captivity, anc] one of its larvae, which had been 

 destroyed by a curious parasitic fungus. Also some small 

 water beetles (Necterosoma penicillatum ) taken out of very
