Until the publication of the Monograph on the Mollusca of the Great Oolite (by 

 Messrs. Morris and Lycett), but little was known respecting the fossils of this forma- 

 tion. This monograph, too, was not so much an account of English Great Oolite 

 fossils in general, as of a particular assemblage, restricted for the most part to a 

 limited area around Minchinhampton. The above lists of species appear to me 

 chiefly interesting as tending to remove the apparent isolation of the Minchinhampton 

 fauna. As in Gloucestershire, so in Oxfordshire, the Cephalopoda seem to be but 

 sparingly distributed in the Great Oolite ; and but few species of carnivorous Gaste- 

 ropods°have yet been detected in the same formation near Oxford. 



As compared with the same zone of life at Minchinhampton. the upper beds of the 

 Oxfordshire Great Oolite would seem apparently to have been deposited in seas of 

 greater depth and of more tranquillity. Bivalves are commonly found with the valves 

 united and the ligament preserved, and large reef-like masses of coral are not unfre- 

 quent. In Oxfordshire a large proportion of the Great Oolite fossils range upwards 

 into the Forest Marble and Cornbrash, and no inconsiderable series occur even as high 

 as the Coralline Oolite. Five species have not previously been detected in this for- 

 mation, and eleven shells are quite new to science. From the Forest Marble at Islip 

 and Kidlington I have collected the following species : —
