Fig. 142, BM(NH) 10297, holotype; 142A, x 65; 142B, thick-walled zooecia, x 152; 142C, edge of overgrowing subcolony, x 42. Fig. 143, BM(NH) D57744, worn gynozooecium, x 53. Remarks. R. brydonei is often mis-identified ( Canu & Basslcr 1926) as Reptomulticava fungiformis Gregory, 190%, a species which is here regarded as a 'sclerosponge'. Although assigned to Zonatula Hamm, 1881 by Gregory (19096), a more appropriate genus to accommodate this common Faringdon bryozoan is Reptomulticava d'Orbigny, 1854, a genus whose identity is discussed above. The type species of Zonatula, Plethopora pseudotorquata Hagenow, 1851 from the Maastrichtian, does not have zoaria constructed of a series of multilamellar subcolonies. Many species of Repto- multicava develop larger colonies than R. brydonei with a growth-form resembling that of Semimulticavea marginata. Small colonies of R. brydonei may be found encrusting bivalve shells or sponges, but larger colonies are generally recovered detached from their substrata as short stems which are commonly worn. Zoarial morphology resembles that of Tholopora spp. from which R. brydonei can be distinguished by the absence of kenozooecia and the presence of extremely thick-walled autozooecia. Genus THOLOPORA Gregory, 1909a Type species. Ceriopora clavata Goldfuss, 1827, by original designation; Cenomanian, Essen, W. Germany. Remarks. Gregory (1909a) founded this genus to embrace compound 'Radioporidae' composed of superimposed sub- colonies forming short, thick, blunt cylindrical stems. In it he placed seven species: Ceriopora clavata Goldfuss, 1827, the type species; Ceriopora muletiana d'Orbigny, 1850; Domopora colligata Gregory, 19096; Domopora poly taxis (Hagenow, 1851) ?, sensu Vine, 1885 (= Domopora vinei Gregory, 19096); Ceriopora stellata (pars) Goldfuss, 1829 (= Tholopora virgulosa Gregory, 19096); Het
