quite abnormal appearance, as one specimen in my material, in 
which there are some 30 of these secondary mouths. 
One specimen in the collection recalls in some way strongly 
F. moluccensis. The structure of its costae, which consist of single 
rows of blunt spines is exactly the same as in other specimens of 
F. paumotensis. The lower surface, however, is quite flat and the 
upper surface answers in nearly all respects to F. moluccensis. The 
septa have minute dentations. The central parts of the septa of the 
higher cycles with which two septa of the next higher cycle have 
fused are strongly granulated and appear therefore much broader, 
whilst in F. paumotensis these parts of the septa usually retain the 
same thickness as the peripheral part. The central region round 
the axial fossa shows the typical elevation of F. moluccensis, but less 
prominently than in the other specimens of F. moluccensis in my 
material.

The comparatively small specimen has well-developed tentacular 
lobes which clearly project above the neighbouring septa. The 
septa are thin. The dimensions of the corallum are: length 73, 
breadth 50, and height 18 mm.

The lower surface of all specimens in the collection is provided 
with strong spines (fig. 67), which is one of the chief characteristics 
separating this species from Herpolitha simplex (cf. below). 
The youngest specimen in my material is a stalked anthoblast 
(figs. 71 and 72), the dimensions of which are: length 26, breadth 
20 and height 6 mm. There are five complete cycles of septa
