which I collected near the island of Edam in the Bay of Batavia, 
we could detect at the underside buds in various stages of develop- 
ment; they are seen nearly always in the immediate vicinity of 
part of the parent-coral which is overgrown profusely with algae. 
It frequently happens that a bud appears at the underside, just 
beneath that portion of the upperside that is grown over with algae. 
When a Fungia fungites is partly attacked by sea-weeds, the latter 
impart a stimulus to the adjacent tissue, which consequently displays 
a more energetic growth-activity. This greater activity is also mani- 
fested in an increased Skeleton-production, resulting in the formation 
at the underside of larger spines, which are sometimes branched out, 
or even in the formation of buds; at the upper side this intensified 
growth engenders new septa, which are often of an irregular shape, 
while in some cases buds are formed. 
DöperreiN already suspected that calicular budding occurred also 
in Fungia fungites but he could not prove it. In a few specimens 
of this species found near Edam, rather distinct buds were formed 
at the upper-side of the disc; one of these specimens was very 
conspicuous. In this Fungia (Fig. 1) part of the dise is grown over 
with sea weeds of various kinds and with case-worms, which causes 
the tissues of the polype to be destroyed at this spot.

organisms. °*/5 nat. size. 
An abundant growth of algae is also observed over the mouth. 
Greater growth-activity is shown round the attached part which 
generates new septa everywhere at the borders of the destroyed
