Colony encrusting, multilamellar, composed of numerous subcolonies arranged in a CelliiliporciAikc con- tiguration. The subcolonies are subcircular in outline (Fig. 1()7B) and variable in size but often 5-6 mm in diameter. Only one tier of zooecial buds is normally visible at the growth margins of the thin subcolonies. New subcolonies appear to originate by eruptive frontal budding from the centres of established subcolonies. Autozooecia (Fig. 1(I7B) have well-dctincd frontal walls which taper proximally and are well-rounded distally. Aper- tures are circular, and preserved peristomes are thin and low. Measurements. TAM, 0-09-0-10 mm; TPM, 0-12-0-16 mm; FWL, 0-4(M)-6() mm: FWW, ()• 18-0-22 mm. Remarks. Although the solitary available specimen, which encrusts a sponge, is mostly worn, the better-prescr\ed parts resemble an Upper Cretaceous specimen (BM(NH) 02991). Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
