This case slightly reminds us of the aspect (in F. agariciformis 
=F. fungites) of a number of young stemmed Fungiae on the 
Fig. 4. Fungia fungites. Underside. Stemmed bud at a 
defunct part in the middle. Ys nat. size. 
defunct disc. of a coral of the same species, as described by 
SrurcnBury. *) The same aspect was presented by some of the Fun- 
giae I found near the island of Edam. At the underside of one of 
them residues of living tissue were distinguishable, but all the softer 
parts of these corals were vanished and here and there seaweeds 
and serpulids had settled. At the border of all the specimens there 
are a large number of buds, while in a few of them buds have 
also been formed near the central part of the underside. Of the 
latter the stem has a uniform breadth everywhere, in contradistine- 
tion to many at the border, whose stem has broadened at the 
upperside into a disc-shaped young Fungia. The stem of many buds 
adhering to the border of the underside, has bent round, so that the 
dise of the young Fungia is seen at the upperside of the border of 
the old coral. Some of these young corals are overgrown with 
algae, most of them are fully alive and look quite normal. 
STUTCHBURY *) considers the occurrence of young corals on a 
defunct dise of the same species to be something accidental. (‘I 
consider the cases in which young Fungiae are found fixed to the 
underside of others of the same species, to arise from the accidental 
attachment of the young polype”), whereas SEMPER holds that these 
young corals have arisen in situ through budding of the coral; the
