ABSTRACT OF PROCEEDINGS. X. 



lioring were referred to at length, and various theories, 

 anechanical and chemical, advanced by leading conchologists, 

 were compared. 



In a late visit to Baffle Creek, Mr. C. T. White, Govern- 

 ment Botanist, collected a few land shells, the principal 

 being Thersifes parsoni Cox and Thersites blooynjieldi Cox. 

 These were commented upon by Dr. Shirley. 



Mr. H. A. Longman, F.L S., exhibited a Pieropus 

 q)olioceplmlus Temminck, which had been forwarded to the 

 Queensland Museum by Mr. S. C. Smith, from Dulbydilla, 

 beyond Mitchell, Western Queensland, this being a 

 remarkable extension into the interior of the ran^e of this 

 •" flying-fox." 



Mr. C. T. White, F.L S., exhibited: (1) photographs 

 •showing variation in the bark of Eucalyptus hcemastoma 

 jSm., var. micrantha (D.C) Benth., the common " white " 

 •or " scribbly gum,"" also a photograph of a stringy-barked 

 iorm common on the ranges about Toowoomba, which he 

 considered worthy of distinct varietal rank ; (2) tubers 

 ■of the "Weir Vine,"' Ipomoea calobra, Hill and F.v.M. 

 ^gathered by Mr. Donald Gunn, M.LA., between 

 •Goondiwindi and St. George. Mr. Gunn stated that the 

 vines had the same effect on stock as the Darling Pea, or 

 " Indigo " {Swainsona) . The tubers, however, were used 

 as food by people in the districts where the plant occurred. 

 Mr. Gunn's account of the effect of the plant on stock was 

 corroborated by other practical stockmen. 



Mr. H. Tryon and Professors Richards and Johnston 

 took part in the discussions on the exhibits. 



Professor T. H. Johnston, M.A., D.Sc, read the 

 following papers by himself and Miss M. J. Bancroft, B.Sc. • 

 .(a) " Experiments with Certain Diptera as Possible 

 Transmitters of Bovine Onchocerciasis " ; (6) '' Notes on 

 the Chalcid Parasites of Muscoid Flies in Australia." The 

 papers were accompanied by an exhibit of specimens. 

 The discussion was deferred to the monthly meeting of the 

 Society.
