This bed will form a valuable index of horizon ; and it is supposed 

 that it re-appears in the coast at Illaunglass, some 6 miles further south.

A similar fauna is stated to occur at several places on the coast 

 between Kilkee and Loop Head ; but 1 was unable to examine these 

 sections. 



The Geoloyical Succession near Foynes, County Limerick. — The 

 sequence of rocks in the Foynes district is almost complete ; and all 

 the beds can be examined from the Lower Limestone, which to the 

 east extends from the Shannon along the west of Aughinish Island, 

 and follows a line almost due south. The Lower Limestone is very 

 fossiliferous, especially in the upper beds. 



The Upper Limestone is as a rule dark blue, and has layers of chert. 

 Fossils are not so abundant as in the lower beds ; but Zaphrentis and 

 other corals, and Brachiopoda are to be found {Spirifer triyonalisy 

 Productus semireticulatus).
