Corryville or Chiloporella nicholsoni Beds. 
In this division the limestones are thinner and less frequent 
than in the quarry beds and the shales more yellowish. Blue 
shale also occurs. Price Hill and the higher hills of the 
“Cincinnati island” (see azfe, p. 50) expose these beds. 
Formerly Corryville abounded in exposures, but has been so 
covered with residences that the underlying strata are now 
seldom seen. One of the most characteristic bryozoa, very 
abundant in these beds, if not restricted to them, is the 
Chiloporella nicholsont. At the present time Fairview Heights 
affords a number of exposures of these layers. Owing to 
these strata having been largely cut into in the course of the 
transformation of the hill tops into the residence portion of 
the city, their fauna has become well known. 
In addition to the species ranging through the Lorraine, 
the following occur:
