Rem ark s : FORSKAL (1775: 134) mentioned a further specimen, different from Madrepora fungites,
one foot long and 5 inches broad, with large lamellar teeth. CROSSLAND (1941 : 40) opined that this
could only be Herpolitha limax. However, we believe that FORSKAL had Ctenaetis eehinata at hand,
which occurs in the Red Sea more fr equently than H. limax.
Additional rem ark s to genus Fungia :
GARDINER (1909 : 278) reported on four specimens of Fungiaacutidens STUDER, collected by CROSS­
LAND in the reefs of Suakin . We could not examine these specimens, therefore we mention this species,
previously kn own solely from New Ireland and doubtfully from Tahiti, o nly in an appendi x.
CROSSLAND (J 952) mentioned the occurrence of F. paumotensis STUTCHBURY in the Red Sea. His
own specimen does not come from there and it is , after his own words, an abnormal specimen. We believe
that CROSSLAND 's note depend on a misunderstanding. Also VERON & PI CHO • (J 980) report on F. paumotensis
from the Red Sea. We do not know ro which authority they refer, no other aut hor has ever
published F. paumotensis from the Red Sea. The next locality, where F. paumotensis was found, is
Aldabra (ROSEN, 1971 ).
Genus Ctenaetis VERRI LL, 1864
Ty pes pee i men : Madrepora eehinata PALLAS, 1766.
G e n e ric c h a rae t e r s : Corallum elongate with a long, mono- ro polystomatous axial furrow.
Septa unequal in height with coarse, elongate-compressed, large, spinose teeth. Costae reduced, unequal,
represented by strongly spinose, arborescent spines. The genus is monospecific.
WELLS (1966) has put Fungia eehinata into the new subgenus Ctenactis, and he has established a new
genus, Herpetoglossa , homeomorphic with Fungia (Ctenaetis) , with the same septo-costal structures and
containing one species, H. simplex (GARDINER ). The main difference between these two forms consists
in the development of several calicinal centres in the axial furrow of H. simplex. Wells considers Herpetoglossa
as a very recent polysromarous derivative of Fungia (Ctena etis).
But nearly all authors agree, that F. (Ctenactis) eehinata can be polycentric, roo. Already EHR E BERG
(1834 : 274) had the varieties platystoma and polystoma. Then KLUNZINGER (3, 1879 : 66), DOEDER­
LEIN (1902 : 104), GARDINER (1909 : 274), ,'vIATTHAI (1924: 42), BOSCHMA (1925: 216),THIEL (1932 :
67 ), CROSSLAND (1952: 15 2) write that septa of opposite sides fuse at the axial fossa and divide it in
secondary centres, at least the tendency for divid ing is present. Also VERON & PICHON (1980: 171)
state that F. eebinata " may have rarely one, very rarely two, secondary centres". It is not applicable to
separa te specimens with null , one or two secondary centres as F. eehinata from those with three and
mo re under the name H. simplex.
