Therefore, betusora is here proposed as a nom. nov. for the tuberosa of Reuss (1874). The types of Diastopora acupunctata Novak, 1877 were not available for study during a visit to the Narodni Museum, Prague during June 1986- However, judging from Novak's figures and Voigt photocards of this material, some of Novak's specimens belong to Reptomultelea betusora, at least one to Reptomultelea sarthacensis d'Orbigny, and several others cannot be identified with any reasonable confidence. Diastopora confluens Reuss, 1846 (non Roemer) is placed tentatively in the synonymy of R. betusora. According to Prof. E. Voigt (pers comm., February 1987), the type speci- men was destroyed in 1956, but a similar specimen exists in the collections of the Naturhistorisches Museum, Vienna (Voigt photocard 8650). Reptomultelea betusora is characterized by the presence of small eleozooids of the trifoliozooid type. In this respect it resembles R. tuberculata (d'Orbigny, 1853) but the latter species has more elongate autozooidal and eleozooidal aper- tures. Specimens of R. betusora from the Turanian of Sarthe and from the Coniacian of Etretat have rather larger zooids than Upper Cenomanian material; however, the difference is not considered sufficient to warrant species separation. Colonies are often nodular in form, like those of R. levinseni sp. nov. (see p. 77) and R. sarissata Gregory (p. 94) which also occur in bryozoan-rich chalks of the Seine Maritime. Distribution.
