CV1 Text-figure 1 L—Plots of scores on the first three canonical vari- ables in the final canonical discriminant analysis distinguishing spe- cies of bidirectional flabelloid colony forms. Each point represents one colony. The polygons enclose clusters of colonies belonging to the following species: 1 = Thysanus navicula. 2 = Hadrophyllia saundersi. 3 = Manicina geisteri. 4 = M. grandis. and 5 = M. jiingi. ''Teleiophyllia navicula" Duncan. 1864, both of which are from the Neogene of the northern Dominican Re- public. Qualitative comparisons of measurements made on holotypes of these two species suggest that "T. grandis" can be assigned to cluster #4, and 'T. navicula" to cluster #1 (Tables 11, 12; Pis. 11, 14). The other three clusters (#2, 3, 5) are unique, and therefore are described as new (respectively Hadro- phyllia saundersi, n. sp.; Manicina geisteri. n. sp.; Manicina jungi. n. sp.) in the present monograph. Bi- directional flabelloid forms also occur in the Mean- drinidae in the Caribbean during the Neogene, and some have morphologies convergent with the five fa- viid species with bidirectional flabelloid forms. Cluster #4 (Manicina grandis), for example, is morphologi- cally similar to the late Miocene to early Pleistocene meandrinid species. Placocyathus variabilis (Duncan. 1864). from which it differs by having well-developed costae. spongy columellae, and more numerous septa (Text-fig. 13). In contrast to bidirectional flabelloid colony forms, only eight specimens in the NMB collections have uni- directional flabelloid forms. Five of the eight speci- mens were poorly preserved or fragmentary; therefore, measurements and counts could only be made on three specimens (CCD 2193, 2194, 2198). The same four variables (Text-fig. 8; Table 6) were measured as on the bidirectional flabelloid colony forms. The data were then added to the data set with the specimens having bidirectional flabelloid grow
