were noted from this colony, but probably more existed. Some 

 forty-nine species and varieties have been collected by Mr. 

 Tepper in the neighbourhood of Adelaide, chiefly about 

 Clarendon. A short discussion ensued, and Mr. Tepper men- 

 tioned the localities where different varieties of orchids could 

 be found, such as Stonyfell, Clarendon, Kensington, and 

 Grovernment Farm, and he said sandy deep ground was favour- 

 able to the flower. 



ForETH Evening Meeting — Tuesday, July 14, 1885. 



Professor Tate occupied the chair. There was a moderate 

 attendauce. One new member was elected. Dr. Magarey 

 exhibited some shells. Professor Tate gave the names as 

 Obeliscus hruniiea, a rather rare shell, from Gienelg ; Anatina 

 gracilis and Marcia faba, from the mouth of the Onkaparinga ;. 

 and Golumhella hidentata and Mitra Tatei, from Salt Creek ; the 

 first had not yet been catalogued as a South Australian shelL 

 Mr. J. Gr. O. Tepper showed an interesting collection of South 

 Australian seaweeds. Professor Tate showed fossil teeth of 

 Ceraiodus, found in the central lake region of Australia, 

 associated with remains of the Macrop us atlas ; a toe and bones. 

 of an emu-like bird, crocodilian remains, and part of the bony 

 carapace of the turtle. It seemed highly probable that the fisk 

 belonged to the same species as that living in Queensland, G. 

 Fosteri. In 1872 Mr. Krefft found the teeth of the Ceratodus- 

 in the conglomerate in the basin of the Condamine Eiver, m 

 North Queensland, which he considered to be of an extinct 

 species, and last year Mr. De Vis, curator of the Brisbane 

 Museum, found specimens in another locality, and considers- 

 that they are not different from the living species.- Professor 

 Tate thought from these evidences that his speculations on the 

 existence of a large fresh-water area in Central Australia were 

 proved to be correct. 



Mr. W. Howchiu, P.Gr.S., then read a paper on "Storms and 

 "Weather Charts." The lecturer dealt with the construction and 

 uses of the barometer, with special reference to its application to 

 meteorological science. The laws regulating storm phenomena 

 were explained by means of the blackboard, and large diagrams 

 were used to illustrate the hydrography and principal storm 

 tracks .as observed in Australia. The isobaric lines and signs 

 used in the delineation of weather charts were interpreted, and 

 some useful observations were given bearing upon Australian 

 climatology. The storms which occur over the southern half 

 of Australia, the lecturer remarked, almost invariably pass- 

 from west to east, first making themselves felt in Western 

 Australia, skirting the coast with their centres well off the
