Although the corallum of Fungia cyclolites is very thick, yet a 
great many broken specimens that were regenerating could be 
collected. The regeneration of the broken specimens which were 
found in the same locality as the normal ones always tends to 
restore the original circular shape of the corallum (figs. 25—38). 
Everywhere on the line of fracture new parts are developing which 
form a continuous zone of growth and do not differentiate into lobes 
as in Diaseris. The outcome is always a circular corallum whose 
septa and costae present some irregularities, but on the whole 
these are of little importance. 
As a result of the regeneration often new mouths originate at 
the upper surface of the corallum (fig. 33). From these mouths the 
septa more or less regularly radiate towards the periphery of the 
corallum. 
Secondary mouths are also sometimes found in specimens that 
in other respects appear to be quite normal. One specimen with 
a normal lower surface has three secondary mouths at the upper 
surface. Between the largest of these and the primary mouth the 
septa belonging to each of them are elevated and have grown 
together, whilst a kind of wall has developed at the boundary-line 
of the two sets of septa. 
Besides specimens in which budding has taken place there are 
also some specimens showing phenomena of fission. In the specimen 
represented in fig. 46 the original mouth has divided into almost 
equal parts by the fusion of some opposite septa in the short axis 
of the corallum. This specimen presents no further irregularities. 
In some cases, however, the fission of the mouth is the result of 
the decay of a portion of the central part of the corallum. Then 
some of the septa may loose their living tissue for the greater 
part of their extent. The neighbouring parts then grow out radially 
around new secondary mouths over this dead portion. By this 
process some of the septa of the new portion are at right angles 
with the original ones. Fig. 45 shows another case of regeneration of 
the corallum over a portion that had died off. Originally the 
regeneration had begun in two different places; at last the two 
resulting new parts fused at the line where they met. In other 
specimens the further stages of this kind of regeneration are found, 
especially when it began when the corallum was still extremely
