COERELATION OF BEDS SOUTH OF CaRRICKHILL FAULT. 



These beds are characterized by the abundance of Caninia cornucopiae 

 (" cornu-bovis " stage) and Spirifer clathratus. Zaphrenti'i densa, Michelinia 

 cf. tenuisepta, and Ma.rtinia pinguis are alsojairly common. This agrees with 

 y of Burrington/ except in the matter of Spirifer clathratus, which, however^ 

 is the dominant Spirifer in y of Belgium.^
