bear a striking likeness to tlie jouiig Fungiae, described by Bourne. 

 Vaughan') also points out that it has not yet been proved that the 

 first twelve septa of Fungia appear simultaneously. 



In tiie development of Cdri/op/n/Ilia'') there is one stage in which 

 the skeleton agrees very inucli with tiie stage illustrated in Texifig. i. 

 However, the preceding processes difïer in the two corals; whereas 

 in CnryophylUa the septa are formed prior to the theca, the reverse 

 takes place in Funyla. In Curi/ophi/l/ia, tiierefore, the septa have 

 outgrown the theca much sooner than in Fungia. 



So while a great number of small buds appear at the margin, 

 and several large ones on llie under surface, the tissue is dying off 

 by slow degiees. The result is a defunct specimen with a large 

 number of living buds of different age. JMany authors') look upon 

 such buds on defunct specimens of the same species as having 

 originated from larvae. 



In a previous paper I advocated my view (hat these young 

 Fungiae must be considered as buds"). My experiment yielded all 

 sorts of intermediate stages between normal specimens and defunct 

 ones with buds. The large buds that may arise on tiie aboral surface, 

 are in their earliest phase so large already (up to 12 mm. in diameter) 

 that it is a priori highly improl)able that they should have been 

 formed from lar\ ae. Besides the lateral tissues of tiie bud are 

 connected wi(h those of Ihe parent, while the basal living jiarts of 

 the bud overlie the skeleton of the old coral, which results from 

 the way in which the columella is formed in these buds. The 

 trabeculae of their columella namely are generated between and on 

 the unaltered spines of the coslae of the parent coral.

Also the youngest stages of Fungia patella, described by Gardinee (loc. cil.) 

 are probably buds of a specimen, of which the remaining part of the living tissue 

 had been destroyed. 



■*) loc. cit. Saville Kent (The Great Barrier Reef of Australia. London, 

 1893) also deems it most probable that these young Fungia are buds, originating 

 from the remains of the living tissue.
