A few specimens are lobate, and by an excessive development of the lobes, they have become, to a small extent, subramose. At rather unequal intervals, averaging perhaps 0.1 inches, the surface exhibits groups of cells slightly larger than the ordinary, which may be raised into low, rounded monticules, or remain on a level with the surrounding plane of the surface. Cells regularly arranged in diagonally intersecting lines, about 12 in the space of 0.1 inches, separated by interspaces, usually of less width than the diameter of their orifices, which has averages of about 0.001 inch. Cell apertures are distinctly floriform, the wall at each of the indentations, being raised into a small spine, representing the surface extension of the spiniform tubuli. Interstitial cells numerous, but not readily recognized externally, being shallow, and much obscured by the spiniform tubuli\u2026<\/li>\n<li>This species differs from all the other species of the genus now known, in its greater regularity of cell structure, and more numerous interstitial tubes.<\/li>\n<\/ul>\n<p>[\/accordion] [\/accordions]<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum:\u00a0Bryozoa Class:\u00a0Stenolaemata Order:\u00a0Trepostomatida Family: Mesotrypidae Genus: Atactoporella Species: Atactoporella typicalis (Ulrich, 1883) [accordions title=&#8221;&#8221; disabled=&#8221;false&#8221; active=&#8221;1&#8243; autoheight=&#8221;false&#8221; collapsible=&#8221;true&#8221;] [accordion title=&#8221;Taxonomic Details&#8221;] Taxonomic History (Nickles &amp; Bassler, 1900) 1883 Atactopora typicalis Ulrich, Jour.
