Figs 174-180 1899 Reptomultelea tuberosa d'Orbigny; Gregory: 320, fig. 37. Material. Holotype: BMNH 36746, 'Albian, Upper Greensand', Ventnor, Isle of Wight, England, Norman Col- lection. This specimen comprises one large piece (70 x 45 mm) in matrix, a coated stub with several small fragments, and 7 fragments mounted in two cavity slides. Although the horizon is given as Albian, the close similarity of the matrix to that of a better localized paratype specimen (D58206) from the Isle of Wight suggests that the specimen almost certainly comes from the Lower Cenomanian (carcitanense Zone) Glauconitic Marl (formerly known as the Chloritic Marl). Paratypes: BMNH D44610, 'Upper Greensand' [? Glauco- nitic Marl], Niton, Isle of Wight, Ford Colin. BMNH D58206 (2 fragments), Lower Cenomanian, carcitanense Zone, basal conglomerate of the Glauconitic Marl, Rocken End, Isle of Wight, A. Gale Colin. BMNH D59207, 'Chloritic Marl', St Catherine's Point, Isle of Wight. Name. With reference to the two prominent tubercles at |either end of the hinge line. Description. Colony encrusting, multilamellar, characteris- tically large with up to at least 35 layers, each layer about 0-25 mm in thickness. Overgrowths (Fig. 179) develop by eruptive budding onto the colony surface, often from several closely- spaced pseudoancestrulae; pseudoancestrula aperture about 0-14 mm long by 0-11 mm wide; peri-pseudoancestrular zooids usually autozooids, occasionally eleozooids. Ances- trula not observed. Organization fixed-walled. Autozooids (Fig. 174) of very large size, frontally elon- gate, 2-3 x longer than wide, often hexagonal in outline shape, rather elongate and pointed distally; frontal wall occ
