No. 8111, Genus STEPHANOPORA Kirkpatrick, 1888 Zooecia with semicircular orifice, lower margin straight, not den- tate, without sinus; peristome raised posteriority; from anterior margins of walls thus formed, a process is given off on each side uniting in front to form with posterior wall a tubular peristome incomplete below. From lower margin of peristome a broad branched process is given off unit- ing with processes from other zo- oecia to form a secondary cribri- form roof (Kirkpatrick).

B. Cell showing semi- circular shape of the orifice. (After Kirkpatrick, 1888. porous. The frontal is smooth and bordered with small areolar pores; it bears a median and lingui- form avicularium. There are two distal septulae and 7-8 lateral ones. The apertura is semicircular. No oral glands; no avicularian glands. The colony is radicelled and formed of lamellar segments united by the radical fibrils; 18 tentacles. Genotype.—Pseudoflustra (I'lustra) solida Stimpson, 1853. Range.—Recent (northern seas). Levinsen, 1887, and Waters, 1900, are not in accord as to the form of the ope
