REMARKS

Beauvais (1982) mentioned that the holotype of this species is lost. A holotype never existed; Felix (1903) mentioned various syntypes. Beauvais (1982) selected as the “ neotype ” a sample illustrated by Felix (1903: textfig. 9). This figure shows a magnified detail of a transversal coral section and, therefore, it cannot be attributed to any sample. Moreover, the neotype is invalid because it does not fulfil the IRZN. There is one syntype available (BSPG 1878 XI 413#1), which is the sample that has been already studied by Pratz (1882 -83) and which is also mentioned by Felix (1903).

OTHER SPECIES

Felixaraea reticularis ( Oppenheim, 1930) . The type material (HUJI 24850) was not available for study. According to Beauvais (1982), it has the following dimensions: c 18-21, s 180.

Felixaraea pollicaris ( Oppenheim, 1930) . The type material was not available for study; moreover, according to Beauvais (1982), it is thought to be lost. The specimen illustrated in Oppenheim (1930) is very eroded and shows approximately 120 radial elements. According to Beauvais (1982), this species is distinguished from F.pratzi by its smaller calicular diameter.

Felixaraea gigantea ( Oppenheim, 1930) . The holotype by monotypy (BSPG 1878 XI 413#2) is (according to Oppenheim [1930]) a specimen illustrated by Felix (1903: textfig. 9, pl. 17[1b]) and was originally assigned to H.pratzi . Certainly, the specimen was not figured by Felix (1903) because text-figure 9 shows a detail of a transversal section, and pl. 17, figure 1b shows a a detail of a longitudinal section whereas the type of F.gigantea is not sectioned. Felixaraea gigantea was distinguished by Oppenheim (1930) as a new species on the basis of its large diameter and large number of radial elements (c 58-70, s 250).

Other species originally assigned by Oppenheim (1930) to Haplaraea were not considered by Beauvais (1982); they may not belong to Haplaraea (this genus did not reach the Late Cretaceous) and very probably did not belong to the Felixaraea .

REMARKS

The sample reported (but not figured) by Baron- Szabo (1998) shows less perforated radial elements. The specimen MNHN.F.R10953 is not catalogued as holotype, but corresponds to the illustration in Alloiteau (1952).
