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 --1- - t -f ',.11- thPRQqrP YnelP rqlT P ar(1 l nln Prond-, arranged in concentrically carved lines showing much the 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 of i mnultifld)rculata, and Ji rectangularis does not alwa play this arrangement of pores over the whole surface. elevated spiny angles which characterize the cell walls of tl named species are not always apparent, and are sometimes observed on the latter form. The undescribed form is too i allied to the others to warrant a separate description or desig The wide variation in form and features would seem to it that at most only varieties should be claimed for these The genus Chleteles to which the four succeeding species signed was originally thought to include forms like the la its author described the increase of its cells as taking pl division. In most of the forms in which the method of it of parts has been made out it has been found to be by a di process, and so the new genera iJ/onticulipora stenopvore were founded, and into these genera were gathered those that were found to disagree with the original genus in this r The most that we can say of some of these is that they
