Septa, 24 in number, with an arrangement exactly the same 
as that given by Bernard, in his Catalogue of ’'The Genus Goni- 
opora." There are tv/o directive septa which fora a plane of sym- 
metry across the calice. The tertiaries fuse to the sides of the 
secondaries. On each side of the plane of symmetry, there is at 
one end of the calice a triplet composed of a secondary and two 
tertiaries fused to its sides, this secondary does not fuse to a 
primary. The septa of the two other systems on the same side fora 
two quartets. The tertiaries fuse to the secondaries as just 
described, but the secondary fuses by its inner end to the inner 
end of the primary (Bee PI. , figs. , for a photo- 
graphic illustration of the condition, and also a diagram.). 
The septa are rather thick, as thick as or thicker than the width 
of the interseptal loculi. The septal margins are rather closely
