Ordinary Meeting, April 11, 1918. 



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



chair. 



Nomination. — A. H. Elston was nominated as Fellow. 



The President drew attention to the albums containing 

 the portraits and signatures of the officers of the Society from 

 its formation in 1853. This was fairly complete, and would 

 be kept up to date. 



Exhibits. — Mr. Walter Howchin, on behalf of the 

 Museum Director, exhibited a sand-cementing fungus. The 

 object is 6 inches in length, half of which is composed of a 

 cylindrical stem from f -inch diameter at the base to 1 inch at 

 top of the stem. The distal end is pyriform, 1^ inches in 

 diameter, ending in a bluntish point containing a crateri- 

 form cavity. The organic structure is limited to mycelium, 

 which interpenetrates the mass and cements the sand grains, 

 giving the object a definite outline. The specimen came from 

 the Pinery, 12 miles from Balaklava, and was handed in to 

 the Museum by the Rev. J. Blacket. Mr. L. K. Ward 

 exhibited a stone collected by Mr. Winton from the New Burra 

 Mine, containing fossil markings of Cryptozoon, this being the 

 first known specimen from South Australia. Mr. E. Ashby 

 showed the following birds: — Porzanoidea plumb ea immacu- 

 lata (eastern spotless crake), obtained from near Cape Jervis 

 in March, with eggs of same from Tasmania ; Porzana fluminea 

 (eastern spotted crake) from Sandford, Tasmania, immature, 

 received last February; Hypotaenidia brachypus (slate- 

 breasted rail) from Blackwood; and H. philippensis australis 

 (eastern buff-banded rail) from Blackwood. Mr. Edgar R. 

 Waite showed photographs of a drain into which millions of 

 fish had been collected by the reclamation of a swamp on the 

 River Murray. Mr. J. M. Black exhibited an orchid new 

 to South Australia, which he believed to be Gcdadenia con- 

 r/esta. Mr. A. M. Lea exhibited three samples of weevilly 

 wheat. The largest of these had been covered with 20 inches 

 of sand, but in 25 minutes some of the weevils had 1 worked 

 their way to the top. Also a large number of ferment flies 

 that had been attracted to strong methylated spirits. Also 

 two bombycid moths resulting from larvae found by Mr. 

 Ashby last November. Also, on behalf of Mr. E. L. Savage, 

 a live lizard, Moloch horridus, that had survived for some 

 months by feeding on ants which had been induced to visit 

 the box in which it was confined.
