CARBONIFEROUS ROCKS OF THE SOUTHERN HEMISPHERE. 275 



had left Adelaide, and suggested that as it was in the Inman that the 

 first evidences of glaciation were recognised in Australia, perhaps some 

 native name appropriate to the locality could be selected for this purpose. 

 With the assistance of Dr. Stirling I have paid some attention to the 

 matter in examining the native vocabularies of the district. The tribe 

 which occupied the valley of the Inman and adjacent coast was the 

 Ramin'yere (accent on second syllable, and the following four letters 

 in two syllables = ye-re). The name Inman is euphonious, and was used 

 by Selwyn, and has the advantage of being on the map. Which of 

 these two names should be selected for the purpose is a question that 

 the Committee might consider. 



4. The glacial beds of South Australia, now under consideration, 

 can only be placed in chronological relationship with other glacial beds 

 of Australia by inference. The grounds of such a reference are as 

 follows : — 



(a) Stratigraphical evidence. — In all cases, and they are very 

 numerous, where the base of the glacial beds come under observation 

 they rest on a Cambi'ian floor ; and in several localities where the upper 

 limits of these beds can be seen, they exhibit an eroded surface covered 

 with the lowest members of the marine Tertiary. The stratigraphical 

 limits are therefox'e post-Cambrian and pre-Tertiary. 



(b) Lithological evidence. — The general aspect of the beds, their 

 degree of induration, as well as other stratigraphical features, show a 

 close likeness to the Bacchus Marsh series. 



(c) Evidence by exclusion. — There is no known Glacial period that 

 occurred in Australia that these beds can be reasonably correlated with 

 other than the Permo-Carboniferous. It is scarcely likely that a glacia- 

 tion on so large a scale as occurred in the Inman Valley district should 

 leave in Australia but one surviving evidence. Yet, although the 

 circumstantial evidence is very strong, it cannot be regarded as demon- 

 strated. 



With respect to the remaining questions, I have not had sufficient 

 experience to warrant my expressing an opinion.

Questions 1, 2, 3. I prefer a general Australian name for the 

 whole formation, with locally named subdivisions. For the general 

 name, I think Hunterian is to be chosen, (i) because of priority of use, 

 (ii) because of the extent and perfection of development of the beds 

 in that district, (Hi) because the relationships of the different members 

 have been more completely studied and determined there than else- 

 where. I oppose strenuously the use of any such general term as 

 Permo-Carboniferous, Carbo-Permian, or Permian, because I am by 

 no means convinced that the beds in question are strictly homotaxial, 

 even, with beds of those names in different parts of the world. The
