small. In these cases also often some irregularities have developed 
at the upper surface: the mouth may divide itself and a number 
of secondary calicles surrounded by more or less radially arranged 
smaller septa often develop in the regenerated portions. 
In the above described specimens the secondary mouths are 
usually surrounded by septa that are more or less arranged in a 
radial manner. A much more common phenomenon in F. cyclolites 
is the occurrence of smaller secondary calicles between two larger 
septa (fig. 48). The mouths of these secondary calicles are but 
partly surrounded by new septa, the greater part consists of the 
septa of the mother-corallum. In the central part of the bud the 
septa of the mother-corallum have partly been resorbed, and in 
the axial groove, that has developed by this process, a few papillae 
of the columella are often visible. The arrangement of the septa 
in these secondary calicles shows some likeness with that in the 
secondary calicles of Herpolitha. 
Among the larger specimens from Banda there are a few which 
show a close resemblance to the specimen that was described by 
Dbderlein as a variety of Fungia elegans (1902, p. 80 and Taf. 
IV, figs. 3 and 3 a). These specimens are nearly circular, the lower 
surface is concave, the marginal parts are comparatively thin, and 
the central part of the upper surface is much elevated. In side 
view (fig. 24) the free edge of the septa shows a distinet coneavity. 
The axial fossa is when compared with typical specimens of F. 
cyclolites, very short. Between these specimens and those of the 
usual form there are in my material all iniermediate stages. Ac- 
cording to Doderlein the specimen described by him constitutes 
an intermediate stage between F. elegans and F. cyclolites. The 
specimens in my material also remind us in some respects of F. 
elegans,' but there is no doubt as to their identification with F. 
cyclolites. One of these specimens shows a slight difference in the 
structure of the costae: these are covered with somewhat smaller 
spines than is usually the case in F. cyclolites. 
Some specimens of a Diaseris-hrm were dredged at a depth 
of 12—18 m. Most of these have separated themselves into the 
composing wedge-shaped fragments (figs. 40—44), only some of 
them are more or less complete. They represent the Diaseris-^orn\ 
of Fungia cyclolites, which results from a comparison of these
