4. I found these stemmed young Fungiae only on the dise of the 
defunct Fungia and not on the defunct coralfragments in the neigh- 
bourhood. If these young polypes had arisen from a swarm of larvae, 
which had settled down at the same time or at different epochs, a 
few would no doubt have found a base of attachment in the 
neighbourhood. 
Colonies of fixed young Fungiae (Anthocormus) are especially known 
of Fungia fungites. Of Fungia actiniformis Q. et G. fixed young 
corals have been described by Sruper '). Afterwards no more mention 
is made of anthocormus-formation in this species. Still, it seems to 
occur occasionally; as I found on the reef round Edam about 24 
young colonies of Fungia actiniformis. The number of buds at every 
anthocormus differs largely. One of these specimens possesses 48 
buds or stems from which the young coral has detached itself. 
Upon a number of these stems, a new bud is already developing. 
The largest young Fungia, found fixed to an anthocormus, has a 
diameter of 5 eM. 
Besides the budding at the anthocormus, also lateral budding occurs 
in Fungia actiniformis. The method of lateral budding, occurring so 
frequently with #7. fungites when the tissues of this species are 
partially destroyed by algae, seems to be very rare in J”. actiniformis. 
I found only one specimen, exhibiting this mode of budding. Three 
fourths of this Fungia was defunct. Only the remaining fourth was 
covered with living tissue and bore tentacles. There is a bud about 
midway between the border and the centre at the underside on the 
boundary between the defunct and the living part, still in the latter. 
The septa of the bud, arranged radially, are modified spines, but 
much larger than those of the environment and distinctly flattened. 
The septa are over their full length attached to the underside of 
the parent-coral, a stem has not yet been formed. 
Another very peculiar mode of budding seems to occur rather 
frequently in HF. actiniformis; I found near Edam 10 specimens 
which exhibited it. 
These buds oceur at the underside, attached to the scar by which 
the coral had been fixed in its young state to the stem of the 
anthocormus (fig. 6). This scar is covered with living tissue, which 
proceeds into the tissue of the bud. Tentacles are distinctly noticeable
