ABSTRACT OF PROCEEDINGS. rail, 
Prof. Richards exhibited (a) a number of stone axes 
which had been submitted to him by the Queensland 
Museum for petrological examination, and (6) a nodule of 
phosphorite from Talgai. 
Mr. C. D. Gillies exhibited (a) the base of the aorta 
of an ox, opened to show the semilunar valves and the 
apertures of the coronary arteries, and (b) the skeleton 
of the pectoral fin of Ceratodus, illustrating the 
archipterygial type of limb. 
The following papers were read :— 
(1) ** Alteration of Generic Name,” by Mr. J. Douglas 
Ogilby, in which Hurycaulus Ogilby, a genus of belonoid 
fishes, was altered to Tropidocaulus Ogilby. (Communicated 
by the President). 
(2) *‘ Mollusca Common to 8. Africa and Australia,” 
by Dr. J. Shirley. This paper was written to combat the 
notion that a shell found in South Africa must necessarily 
be absent from Australia. The list gives 350 species 
common to the two regions. Opportunity was taken to 
do justice to the memory of Mr. Hugh Cumming, the great 
collector of Pacific Island shells. | 
(3) “ Ziphius cavirostris on the Queensland Coast,” 
by Mr. H. A. Longman. The evolution of Cetaceans from 
four-footed land animals and their remarkable adaptation 
to marine life was briefly outlined and illustrated by the 
architecture of the skull and other bones. 
Contributions to the subsequent discussions were made 
by Prof. Richards, Messrs. White, Muir and Gillies.
