This list of the Lower Cambrian fauna of Australia mio;ht be 



completed by the addition of Salterella Hardmani and Ole7iellus 



Forresti, botli from the Lower Cambrian rocks of the Kimberley 



District of West Australia."^ 



Professor Tate statesf that no less than twenty-three determin- 

 able species from the Lower Cambrian rocks of Australia have 

 been elaborated, and four or five additional ones are represented 

 by forms too obscure for description. 



Of the seven sub-kingdoms of the animal kingdom therefore 

 (if Girvanella be referred to the Foraminifera and the Archceo- 

 cyathinw to the corals), no less than five sub-kingdoms are 

 represented, the Ecliinodermata, and the Vertebrata alone being 

 unrepresented. 



(2) At the Macdonnell Kanges, in Central South Australia, 

 quartzites, conglomerates, dolomitic limestone, limestone, sand- 

 stone and slate have been described by Mr. Brown | § as resting 

 unconf ormably on the A rchsean series, and being capped uncon- 

 formably by Lower Silurian strata. No fossils have hitherto been 

 found in these Pre-Silurian rocks.
