Material. Holotype: VH 10434, Lower Cenomanian, Mulheim/Ruhr, Westfalia, Germany, Klaumann Colin. Name. Parvus, small (L.), with reference to the small size of the zooids. Description. Colony multilamellar with thin layers, each layer about 0-15 mm thick, a transversely folded basal lamina grows free of the bioimmured substratum (?sponge) in the holotype. Ancestrula not observed. Overgrowths (Fig. 243) originate through eruptive budding onto the colony surface (presumably as a result of intrazooecial budding); pseudoancestrula an autozooid with a minute aperture, about 0-09 mm long by 0-06 mm wide, depressed beneath the general level of the colony surface; autozooids in secondary zone of astogenetic change with relatively small, distally rounded apertures; eleozooids in secondary zone of change with short rostra. Organization fixed-walled. Zooids arranged in approximate quincunx. Autozooids (Figs 245-247) small, frontally elongate, on average slightly over twice as long as wide, typically hexago- nal, pointed distally; frontal wall occupying over half of the frontal surface, convex, sparsely pseudoporous; boundary wall well-defined, salient. Aperture (Fig. 248) of small size, on average 1-5 x longer than wide, gothic arch-shaped, attaining maximum width somewhat proximally of mid- length; apertural rim well-developed, prolonged into a tubercle-like structure distally; apertural shelf narrow; hinge bar and teeth not observed. Operculum (Fig. 244) often preserved in-situ, medioproximal surface flat or concave, distolateral edges slightly convex; pseudopores numbering about 16,
