Description. — The zoarium encrusts dead shells and corals. The 



zooecia are distinct, separated by a small furrow, large, elongated, 



elliptical; the mural rim is thick, saUent, crenulated. The opesium 



is large, semielliptical ; the polypidian tube is wide, oblique, salient, 



with an oblique orifice; the cryptocyst is flat, deep, granular. The 



B zooecia are long, narrow; the opesium is elliptical, nonterminal; 



the polypidian tube is visible but not salient.

Diameter of polypidian tube = 0.16 mm. 



Length of B zooecia = 0.85 mm. 



Structure. — The structure is identical with that of Siphonoporella 



dumonti. The mandible of the B zooecia exactly and entirely covers 



the cryptocyst when it is lowered; its form and its size are then 



regulated by the frontal calcification.
