Cells polygonal, those on the tubercles not differing in shape or
size from the others; ten to fourteen on the stem in the space of
one-eighth of a linear inch. The cell walls are sharp, without
intercellular pits or pores, but elevated at the angles so as to form
low points. This description is abridged from that given by that
eminent paleontologist on page 71, An. llep't, before cited.
JIortd'culipora murituberculata is the formidable name borne by this

The third form is almost intermediate between these two ty
