again, but there remain still some irregularities in the course oF 
the septa and costae of the new-formed part. 
In another specimen a bud of very regular structure has grown 
out on the lower surface. It is attached with a broad base to the 
centre of the lower surface. The centre of the upper surface of 
this specimen shows an irregular protuberance which is surrounded 
by some secondary mouths. These irregularities are often found in the 
larger species of Fungia. They sometimes are caused by a crab, 
which lodges in a hole at the base of the excrescence.

Some of the specimens in my material bear a strong resemblance 
to F. concinna, but on account of their having a strongly perforated 
theca these are placed here among F. repanda. 
A great deal of the material (16 specimens from the reef of 
Lontor in the Banda Islands) consists of formerly broken specimens 
which were in different stages of regeneration. When this process is 
still in an early stage semicircular protuberances are visible in several 
places in the region of fracture round the formerly damaged mouth 
or round secondary mouths between the old mouth and the peri- 
pherical parts (fig. 74). In further growth the sides of the different 
semicircular parts fuse and all septa of the regenerating portion 
become more radially arranged in regard to the centre of the 
corallum. In this species, as in all other large species of Fungia, 
the regeneration of a broken corallum always leads to a form 
similar to the original one, Diaseris-Wke lobes are not formed. As 
the regenerated portion is much thinner than the original fragment 
at the lower surface an indication of former regeneration always 
remains as a sharp ridge at the margin of the two portions. Even 
in coralla that already have become circular again such a ridge 
is clearly visible. 
In one specimen about half of the corallum had lost its living 
tissues. At the lower surface four buds have grown out at the 
margin of the dead part. The septa of these buds have developed
