>This superordinal name is employed to include all Elasmobranchii except the Ichthyotomi. The 

 living sharks and rays may be regarded as constituting the types of the group. It is quite probable 

 that a more complete knowledge of the Paleozoic families will cause them to be removed from 

 association with the yet living families.
