The present collections include more than 50 specimens which we place under this species. They
range from 3 to 40 mm in diameter. They are all circular, flat discs. Underside in young stages flat , but in
some adult ones slightly arched . Septa thin , edges microscopically serrated, sides granular. The primary
cycle of septa most exsert around the axial fossa, followed by the secondaries. A central scar of attachment
is visible at the aboral side in many cases. Costae radiate from the ce ntre of the disc to the periphery.
I n some specimens they are of equal height throughout the length , but in some cases they become less
elevated to the centre than at the periphery of the disc .

Rem ark s: C. patelliforrnis is very ncar to C. vaugha ni (BOSCHMA), but in the former species the
costae are of equal height , whilst the latter has alternating costae towards the periphery, every fourth or
eighth is more prominent.
WELLS (1954: 447) gives for the occurrence of C. vaughani among other localities also Red Sea with (?).
We think that he refers here to F. patella from Gulf of Aden, mentioned by VAUGHAN , 1907a, and
GRAVIER, 1911.
So far as we could find out, C. patelliformis was not yet reported from Red Sea.

We have three young specimens in our collection and one from Dr. SCHUHMACHER, which we put to
this species. Most of them resemble very much the one figured by MARE ZELLER (1906).

Rem ark s : MARENZELLER has shown his specimen to DOEDERLEIN , who puts it between patella
and distorta (DOEDERLEIN in litt. in MARENZELLER 1906). F. doederleini belongs definitely to the
genus Cycloseris, though it resembles Fllngia granulosa. But the latter has a greater diameter in adult
stage, and its septa are thinner.
C. doederleini comes very near to C. tenuis, but more material is needed to prove their identity.
