Serpent me Area and Rhi/olites. 267 



The Basalts (Melaph}Tes of Howitt) belong to the upper 

 palaeozoic series, and are frequently much altered. They fre- 

 quently contain geodes and amygdales of chalcedony. Epidote 

 and calcite are abundant as alterations products. 



In conclusion, I desire to express my indebtedness to Professor 

 Skeats, Dr. T. S. Hall, Mr. F. Chapman, F.L.S., Mr. H. J. Grayson, 

 Mr. G. Ampt, B.Sc, and Mr. E. J. Dunn for help in collecting 

 information on this area. At the same time I must offer 

 apologies for the fragmental character and numerous short- 

 comings of this paper, due to extremely hurried compilation 

 from notes, and to its being written under rather unfavourable 

 conditions on the steamer between Melbourne and Adelaide.
