1 to 1.5 mm in greater diameter or length and sa me depth. Primary septal spines almost reach th~ centre
of the fossa , where they sometimes fuse . Secondaries spiny, one third to half the .Iength of the pnmanes.
EC 305 is encrusting, thick, explanate. UndersIde eplthecate, upper sld~ wllh hillocky growths. Greater
spread 80 mm , thickness 8 to 10 mm, in the middle part 20 mm. Corallttes polygonal. Detalls of septal
spines as in EC 304.
EC 1377 and PW7 3519 are thin, foliaceous lobes, 3 to 5 mm thick and 100 and 35 mm broad respectively.
Underside and those partS of the flattened branches, which are not living, covered with epitheca.
Corallites 1 to 1.5 mm , very flat; walls often incomplete. Surface showing a very ragged appearance. Septal
spines in two cycles, secondaries shorter.

We have only one specimen, which we put to this species. Corallum flat , expanded, greater length
55 mm. Underside covered by a thin epitheca. Corallites round, about 1.5 mm in diameter. Walls of neighbouring
corall ites partly united, but often separated and then linked by spines and synapticulae. Septal
spines in two cycles. First cycle spines well developed , extend ing horizontally to the centre of the fossa.
The inner ends of the spines are a little thickened and do not meet. Second cycle of spines short, acute,
sometimes incomplete.

Rem a rk s: This is the first record of this species from Red Sea.
It is curious that this species has not been found any more since WEL LS (1954). It is likely that A.
superficia/is PILLAI & SCHEER, 1976, from the Maldives represents a deep-water ecomorph of A. oce/lata ,
which agai n can be closely related to A. verrilliana. More specimens are req uired to prove their relationship.

We assign six specimens to this species. NS 2244, PW (without No) and Fri 31- 1 are branching,
SLR 3010 is the broken end of a branch. Only the ends of the branches are living, the branches themselves
are covered with epitheca. The corallites are rounded to polygo nal , in a few specimens some are elongated.
The diameter of the corallites is 2.5 to 3.5 mm, few corallites can have as much as 4,5 mm. Septal spines
in two cycles, in bigger corallites also spines of the third cycle present. In the upper parts of the calices
the spines are shorr, lower down in the fossa they are elongated, confluent and forming a columella-like
network. Between the corallites many buds are developing.
