The specimens starred are from a calcareous bed six to seven feet below 

 the lower Trilobite bed, at Wanakah Cliff, which is probably in this horizon. 



d. Calcareous bed, four to six inches. 



This bed rests on the upper Pleurodictyum bed, a thin layer of shale 

 separating them in most places. Fossils are numerous, Splrifer granulosus 

 predominating. This species becomes rare and disappears shortly after, and 

 does not occur again until within a few feet of the Encrinal limestone. Pleu- 

 rodictyum stylopora has completely disappeared from this region. Rliipido- 

 mella comes in, but otherwise the fauna has not changed very much.
