NOTES AND EXHIBITS. 175 



Mr. Froggatt also called attention to a remarkable statement, 

 reported in the last issue of the " Queenslander " (April 21st), 

 from Winton, Q., to the effect that — "Reports received from 

 outside [inland] concur in affirming the terrible mortality caused 

 by sand-flies among marsupials, the latter having entirely dis- 

 appeared from large areas of country. Scores of carcases have 

 been counted, while other marsupials have been blinded, and are 

 being shot by scalpers at very short range." The extraordinary 

 abundance of the sand-flies would appear to be attiubutable to 

 very favourable conditions following upon phenomenal rains and 

 floods. 



Mr. C. A. Siissmilch exhibited some specimens of Eurydesma 

 cordata Morris, obtained from Belford in the Hunter River 

 District. Previously this fossil bivalve mollusc was known to 

 occur only in the Lower Marine Beds (the lowest subdivision of 

 the Permo-Carboniferous System), and has been looked upon as 

 the type fossil for those beds. The main strata at Belford from 

 which these specimens were obtained have been mapped by 

 Professor David as belonging to the Upper Marine Beds. 

 Eiirydeama cordata would, therefore, appear to have a wider 

 geological range than previously supposed, and no longer can be 

 considered as typical of the Lower Marine Series only. 



Mr. T. G Taylor exhibited a specimen of segyrine trachyte 

 (Soda-Trachj'te Series) obtained by him at Rossi val, near 

 Goulburn. The specimen was of interest as a new southern 

 representative of the series. 



Mr. F. E. Grant exhibited a collection of Queensland Crustacea 

 in illustration of the paper contributed by Mr. A. R. McCulloch 

 and himself at the last Meeting of the Society. 



Dr. Greig-Smith showed a colony of an undetermined bacterium 

 growing upon a plate of saccharose-bean-agar. It had spread out 

 over the dr} 7 agar surface in successive small crescentic ridges, 

 simulating the appearance of the plumage of certain birds.
