DIAGNOSIS. — “ Pylentonemidae   with outer shell spherical, pores numerous, closely spaced, simple; pylome circular, surrounded by welldeveloped, but very shallow, circular, unornamented rim. Pylome net ( sensu Holdsworth 1973   ) absent. Pylome rim connecting with one or more of three tricostulate main spines disposed around and adjacent to pylome. Four other tricostulate spines present, none of which approximates to an “apical” spine. Inner spicular system of seven rays arising from the ends of short median bar, each ray connecting with a main spine, the bar and proximal ends of rays sometimes enclosed by small, spherical, inner lattice.” ( Holdsworth et al. 1978: 784).
