V. — General relation op the Oolitic Coral-eaunas. 



The Oolitic Corals, as a whole, indicate the geographical conditions incident to reefs 

 and atolls, and do not represent those bathymetrical states which the Upper and Middle 

 Liassic coralliferous strata appear to have illustrated. A deep oceanic coral-fauna is not 

 found amongst the relics of the Oolites, and the forms characteristic of the reefs are 

 positively aggregated in an upper and lower mass at Cricldey in the Inferior Oolitic 

 beds. 



Dr. Wright noticed some years since ^ an Oolitic coral-reef near Frith Quarry, on the 

 northern spur of Brown's Hill, about two miles from Stroud. There is a corresponding 



1 The numerous forms I consider to belong to Thecosmilia gregaria are not mentioned or considered as 

 species, although they have a very fair claim. There are three varieties very Symphyllian, and two very 

 Heterogyran in their aspect, PI. VII, figs. 12 — 15. There is a well-marked variety of Montlivaltia trochoides 

 at Painswick in the Inferior Oolite.
