Here we might speak of typical magniflora specimens, when only some few further autozooids have developed in the central field. The type specimen of Kolliker's (1880) magniflora (text-fig. 3, 3) evidently shows the commencement of the development of such clusters. On the other hand, we cannot look on this development of the cluster as absolutely characteristic of the species. In several cases the primary polyp and the axis retain their peripheral dorsal position, and the entire cluster in the main keeps its predominantly ventral position on the rachis, with generally.
