This list exhibits in a striking manner the great change which has 

 occurred in the echinodermatal groups, as compared with the oolites, 

 in which ananchytes, cardiaster, and micraster have no place, and 

 diadema, galerites, and salenia are very rare, if they occur at all f . 



f In Dr. Wright's Monograph of Cretaceous Echinida, now in progress, Diadema 

 and Salenia are somewhat reduced by transfer of species to genera constructed since 

 Agassiz gave his classification.
