the Coralline Oolites of the Neighhourhood of Oxford. 143 



rior Oolites. Eighteen species in my list of the Oxfordshire 

 Coralline Oolite fossils have been recorded also from the Infe- 

 rior Oolite ; and the catalogues of fossils from the Coral Rag 

 and Calcareous Grit of Yorkshire and the neighbourhood of 

 Weymouth would supply many more species common to both 

 formations. As the exact boundary between the Coral Rag 

 proper and the Lower Calcareous Grit of the district now under 

 consideration has not been accurately defined, the term " Coral- 

 line Oolite" is used in this paper collectively, to include both of 

 these formations. From the Upper Calcareous Grit (if that 

 stratum occurs near Oxford) I have no fossils, nor do I know 

 of any. 



The principal localities whence these fossils have been pro- 

 cured are, — Headington quarry, Bullingdon Green, the quarry 

 near the windmill on the Shotover Road, another between 

 Cumnor and Besselsleigh, and the well-known pits at Marcham, 

 near Abingdon. The Crenatula Listeri, mentioned in Prof. 

 Morris's Catalogue of British Fossils as occurring in the Coralline 

 Oolite of Shotover (but with a query attached), I omit, having 

 good reason to suppose that the Portland Oolite is the stratum 

 to which it should be referred. Again, Dr. Fitton, in his elabo- 

 rate paper "on the Strata below the Chalk," gives the well-known 

 Liassic Rhynchonella tetraedra as a fossil of the " Oxford Oolite" 

 at Wheatley, but with some doubt. Surely this is a mistake. 

 Omitting these two species, the following series has been pro- 

 cured from the Coralline Oolite of the Oxfordshire district. 

 The species with an asterisk afl&xed are found also in the Inferior 

 Oolite.
