M a t e r i a l: Altogether 4 specimens were studied, mainly from the section at Sedlec.

D i a g n o s i s: Colony encrusting, autozooecia oval, elongate with a smooth, or slightly granular, very convex, frontal wall. Marginal areolar pores small, about 40 pores are arranged on the border of each autozooecium. Aperture oval to semilunar without spines and with a short peristome (calcified lip). Lyrula deeply immersed, small, sometimes not observable. Ovicell slightly immersed into the distal part of the autozooecium; it has a smooth, frontal wall. In ovicelled autozooecia the lateral lips of orifice may overlap the margin of the ovicell.

R e m a r k s: The characteristic features are the elongate shape of the autozooecia with their very convex frontal wall, small areolar pores and the absence of any oral spines.
