The name of Znfra was i:i 1872 transposed by Henry Adams to a 

 turrid species incompatible with the columbelloid type for which the 

 genus had been erected twelve years earlier. May it be that our Turridfe 

 is a polymorphic assemblage in which some pyrenoid elements have been 

 unnaturally included ? It is noteworthy how persistently authors have 

 grouped the smaller Pyrenidse with Turrida\ Chenu referred MarteoJa
