yet they form masses of existing reefs, and were sebundant in the Oligocene. 

 One of the class, i. e. the Protarcea vetusta, appeared in the Lower Silurian 

 formation of Ohio ; but the class was not apparently represented on our 

 area until the Eocene, if we except the Microsolenas, which are very ex- 

 ceptional perforate forms of the Oolites. The absence of these forms must be 

 accounted for by the deficiency of the geological record.
