tissue. At the intact side mouths have originated by the side of 
these new septa, so that ultimately instead of the old lost mouth 
the /ungia possessed about twenty new, small orifices around the 
algae-covered zone. A few of these mouths are environed by new 
septa (see the upperside in the figure); these buds therefore present 
a more regular aspect than the others, in which the mouth is at 
one side surrounded by a semicircle of new, young septa, which 
unite at the other side with the unattacked septa of the parent '). 
Also at the border of the dise of Fungia fungites buds may arise 
by constricting off part of the septa of the parent-polyp and by 
the formation of a new mouth. This, then, is also a case of calicular 
budding. In its initial stage it is seen in the specimen which is 
represented partially in fig. 2. 
Fig. 2. Fungia fungites. Underside. Part of the border is 
grown out towards the underside. % nat. size. 
At its underside a groove is noticeable at some distance from 
the border. This may be a scar of an old wound and the border 
may have been renewed at this spot through regeneration. At the 
periphery part of the border has curved downwards, the border has, 
so to speak, doubled up here and parts of the septa are lying at 
the underside of the disc. For the rest this Fungia looks quite 
normal. Now when this curved portion is cut off, we obtain a bud 
here also, a calicular one at the underside of the parent-coral. 
This budding is seen further developed in another specimen (fig. 3). 
1) In this specimen the algae-parasitism has proceeded right across the 
disc as far as the underside (in F. fungites the disc is provided with pores), 
which also here has given rise to a number of lateral buds, although only 
a small portion of the tissue of the underside has been destroyed. These 
buds are rather large (the largest is 32 X 25 mm.), the oldest have already 
a broadened border, as may be distinctly seen, so that they are attached to 
the underside by a stem.
