Hippoporina rarepunctata ( REUSS, 1847) View in CoL – David and Pouyet p. 174, Pl. 8, Fig. 7

T y p e: Holotype from Baden deposited in the Natural History Museum Vienna under the number 1878.11.36 (identified by David and Pouyet, 1974).

M a t e r i a l: Quite common species; altogether 25 specimens were studied in detail from different sections.

D i a g n o s i s: Colony encrusting. Autozooecia with strongly porous frontal shield and wide semilunar apertures with a wide lyrula. A pair of large, prominent, long but narrow condyles situated on the margin of the apertures. Lateral walls clearly visible. Avicularia adventitious, rare, spatulate, large, situated on the frontal wall with prominent, long palate. Ovicell large, partly immersed into the dorsal part of the autozooecium, no frontal wall preserved.

R e m a r k: David and Pouyet (1974) listed this species among the synonyms of Hippoporina rarepunctata ( REUSS, 1847) . However, the type material shows clear differences: Cellepora rarepunctata REUSS, 1847 has no lyrula, no avicularia and small ovicells when compared with Lepralia seriata REUSS, 1874 .

Emballotheca exhibits the same development of its frontal wall, avicularia, condyles and ovicells. According to Gordon (1984), the general characteristics of Emballotheca also correspond with the studied specimens.
