These 2 genera are types of 2 new groups, the characters of which will

Polypes with calyces, placed on tlie margin of small leaves, or in many oblique 
rows to the left and right of the keel ; “ zooids ” mostly ventral. 
Protoptilince, Polypary long, narrow ; bilateral symmetry only distinct on 
the ventral side j polypes with calyces, placed directly on the keel j zooids ”
