rather prominent, rounded tubercles with concave interspaces.
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
little fellow. iL rectanyularis differs from this in the form and

arrangement as the engraved lines on the surface of a watel
The third form is almost intermediate between these two ty
surface markings, but is of larger growth and has less pror
monticules. The pores are quite generally hexagonal ai
arranged in straight or gently curving lines. This form is
scribed.
  There is some doubt in my mind as to the existence o
constant difference between these three forms. The concen-
rangement of cells is sometimes observable at the ends of br

observed on the latter form. The undescribed form is too i
