Catenicellidae Busk, 1852

Colonies erect, flexible, jointed, anchored by rhizoids; internodes normally of one to three autozooids, with cuticular connecting tubes. Zooid calcification typically smooth gymnocyst; frontal area may include a costal field, a group of windows, or be imperforate. Marginal kenozooids, or pore-chambers, usually with a window over a calcified gymnocyst with communication pores, sometimes elongate (vittae). Distal kenozooids may be elongate and pointed. Orifice D-shaped, or with proximal margin concave or sinuate. Central frontal pore opening to compensation space present in few species. Avicularia single or paired, disto-lateral, or absent. Brooding zooids with enlarged ovicells developed in several ways; either at a branch termination, in line with an autozooid, or as one of a group of two or three autozooids.
