Description
Zoarium only slightly calcified, reaching a length of at least 100 mm, rootlets very delicate. Stalk bifurcating rarely, at an acute angle. Branches with as many as 12-13 longitudinal rows of zooecia, on each surface, towards their distal ends. On the frontal surface all the zooecia are provided with an operculum and orifice, and are very long, parallel-sided, without spines, the orifice terminal, the cryptocyst undeveloped. On the basal surface, the two marginal rows alone possess fully developed zooecia, the remainder having the form and size of zooecia , but without operculum and orifice, the opesia are sometimes greatly reduced by an extensive cryptocyst. Avicularia restricted to the basal surface, occurring at the junction of the distal wall of a marginal zooecium with a kenozooecium; conical, with a nearly semicircular mandible. Ovicells wanting, the fertile zooecium producing an extremely large egg. At the bifurcation; the formation of an axillary zooecium is preceded by the doubling of a row or rows of zooecia in such a way as to provide the median rows of the branches.
