CENSUS OF FORAIMINIFF.RA. 



863 



in most instances, very limited. Had the material at command 

 been greater no doubt a much longer list of foraminifera would 

 have been obtained. Ref. Roy. Soc. Trans. S.A., vol. xvii., 1893, 

 p. 346. 



4. Mirrabuckinna Bore is situated about twenty miles north of 

 the head of Lake Torrens, and forty-three miles in a straight line 

 south-west of Hergott. Six samples were examined, included 

 within the geological horizons of 40ft. and 153ft. The foraminifera 

 noted in the Table below were limited in their occurrence to the 

 first 50ft. of the section. Below this level the beds proved to be 

 gypseous and unfossiliferous. Ref. Trans. Roy. Soc. S.A., vol. 

 XVII., 1893, p. 346. 



5. Williavi Creek is situated on the Northern railway, about 

 125 miles north-west of Hergott. The few foraminifera mentioned 

 in No. 5 column were observed in searching a very small supply of 

 material taken from the heap at mouth of bore that was put down 

 in this locality. 



6. Wilcannia. — I am indebted to Mr. Dombraine for a small 

 sample from the Wilcannia bore, which on searching yielded 

 a few fragments of Bigenerina nodosaria, one of the most 

 characteristic of the Australian Cretaceous foraminifera. 



7. Wollumbilla, Queensland — From gatherings made by the 

 late Rev. W. B. Clarke, F.G.S., and published in " Australian 

 Mesozoic Geology and Palaeontology," by Mr. Charles Moore, 

 F.G.S., Qy. Jour. Geo. Soc, 1870, xxvi.. p. 239; also " Geology 

 and Palaeontology of Queensland," by Mr. R. L. Jack, F.G.S., 

 and Mr. R. Etheridge, jun., p. 435. Mr. Moore floe, cit., p. 231) 

 gives the occurrence of Cristellaria cultrata, Mont., in the 

 Mesozoic rocks of Western Australia, but without locality.
