In "Western Australia, on tlie Grreenoiigh River, apparently on 

 tlie margin of the table-land, there are beds containing fossils, 

 M'hich appear to belong to the Upper Lias and the Lower Oolite 

 or Jurassic. Many fossils common in Europe are found there, 

 such as the following from the Upper Lias — Ammonites saleiisis, 

 A. radians, A. ivalcottii, JS'autlliis semistriatus, Gresslija ilouaci- 

 formis, and Myacites liassi:tnus, the last rather referable to the 

 Middle Lias. From the Oolitic beds of the same locality, we 

 have the following fossils, common to European formations — 

 Ammonites macroceplialus, A. hrocliii, BeJemnites cnnalieiilatiiSj. 

 CucuJtcea ohlonrja ^pliolodonuja ovidam, Avicula munsteri, A. echinata 

 Pecten cinctus, P. calvus, Lima probosciJea, L. punctata, Ostrea 

 marsliii, RhijnchoneJJa variabilis, Cristellaria cuJtrata. The 

 peculiarity of these deposits is that they are lithologicallj similar 

 to the coniemporaneous strata in Europe. Thus the Lias fossils 

 are inclosed in a matrix perfectly identical with a ferruginous or 

 variegated limestone of the Upper Lias occurring near Bath, and 

 the Middle Lias, or marlstoue, is not left unrepresented. The 

 matrix of the Oolite fossils was equally characteristic. Mr. 

 Charles Moore in his paper on Mesozoic Australian Geology 

 (Quar. Jour. Geo!. Soc, London., 1870, p. 2j7,) says "that even 

 had no distinctive fossils been present, a geologist acquainted 

 with the secondary rocks of England and Europe would hardly 

 have failed to refer the greater number of the specimens to the 

 horizon of the Lower Oolitic rocks." In this way, lithologically 

 and almost without the evidence of the fossils they contain, the 

 AVestern Australian specimens might be decided to be contem- 

 poraneous with the lower Oolites, and the upper and middle Lias 

 of this country, from which they are so many thousand miles 

 separated. It is probable also that in the same locality Cretaceous- 

 rocks are to be found. 



On the other side of the Continent, and on the edge of the 

 table, though like AV^estern Australia within the ocean watershed, 

 a number of fossils have been found which may be thus enumer-
