Abstract of Proceedings, 26th September, 1921. 



The Ordinary Monthly ^Meeting of the Society was held 

 in the Geology Lecture Theatre of the University at 8 p.m. 

 on Monday, 26th September, 1921. 



The President, :\Ir. C. T. White, F.L.S., in the chair. 



The minutes of the previous monthly meeting were read 

 and confirmed. 



:\Iiss B. Ludgate, B.A., and Mr. W. B. Alexander, M.A., 

 were nominated for ordinary membership. 



Dr. E. 0. ^larks exhibited a stone tomahawk found in 

 alluvium at Bulimba Point, Brisbane, at a depth of 3 ft. 

 6 in. below the surface. Messrs. Bryan, Bennett, and 

 Longman discussed the exhibit. 



]\lr. 11. A. Longman, F.L.S., exhibited mandibles of 

 Phascolonus gigas and Euryzygoma {Nototherium) dunense. 

 In view of the discussion of species of Nototherium by Scott 

 and Lord (Pr. Roy. Soc. Tas., 1921, p. 2) and their earlier 

 association of De Vis' dune use with Phascolonus, as 

 criticised by the exhibitor (Longman, 2Iem. Qld. Mus., vii, 

 pt. 2, 1921, p. 77), these fossil marsupial mandibles were 

 shown side by side. Not only are the dental characters 

 totally distinct, but the large ectocrotaphyte depression and 

 the as-sociated external ridge readily distinguish all 

 Phasco]o»iyid(e from Euryzygoma du)i€)ise, which is the 

 most specialised member of the Nototheriida? yet found. The 

 fact that the two families probably had a common ancestry 

 does not make less remarkable their present divergencies. 

 The exhibit was discussed by Mr. Bryan and Dr. Marks. 



Mr. H. A. Longman communicated a paper by Mr.
