Colony margin with developing zooids and ooecia. B. Oblique view of two zooids from colony margin, showing details of primary orifice with median lyrula and lateral denticles. C. Suboral avicularium. D. Non-ovicellate zooids with finely dimpled frontal shields. E. Ovicellate and non-ovicellate autozooids with and without suboral avicularia. F. Ovicellate zooids. G. Group of ovicellate zooids showing details of peristome and ooecia. H. Distolateral view of ovicellate zooids, showing details of avicularium and bilobed peristome. I. Interior of frontal shield, showing lyrula, areolae and ooecial communication pore (arrow) in apex of ovicell floor. J. Internal view of orifice, showing lyrula and denticles. K. Basal colony surface with tubular protuberances. L. Interior of frontal shield, showing ring scar and exterior wall microstructure of umbonuloid component. M. Lateral view of zooid, showing peristome, areolae, interareolar ridges and zooidal lateral wall with mural pore chambers.
