Among the specimens collected during the Danish Expedition 
to the Kei Islands there are several that answer to one of Dd- 
derlein’s varieties of this species, whilst it is only with great 
uncertainty that the others can be classed v/ith one of them. As 
moreover in one locality more of these varieties often occur together 
it is of no use to give further details about the distribution of 
these varieties. 
In many specimens of the collection secondary mouths have 
developed on the oral surface of the corallum; in one specimen 
there are even more than forty of these (fig. 73). The first stages 
of formation of these secondary calicles consist only of a deep 
notch in two or three neighbouring septa. Afterwards the parts of 
these septa nearest to the mouth of the secondary calicle grow 
out radially towards the centre of the mouth and new septa are 
formed as excrescences on the septa of the mother-corallum nearest 
to those that have a notch. In the further stages of development 
the septa or parts of septa that belong to the secondary calicle 
become more and more radially arranged around its mouth. In this 
way some of these coralla with a great many secondary calicles 
acquire some resemblance with Halomitra, in which genus the 
secondary calicles develop in the same way. 
There is very little doubt that Halomitra fungites Studer 
(cf. Studer 1901) also is a Fungia in which a large number of 
secondary calicles have developed. The axial fossa of the largest 
calicle in Studer’s specimen is quite different from that of the 
central calicle in Halomitra. Gardiner (1909) already expressed 
his doubts as to the classification of this form among Halomitra. 
Probably Studer’s specimen belongs to Fungia fungites as the 
description of its costal spines seems to indicate. 
In some specimens buds have developed at the lower surface, 
usually in the neighbourhood of a part of the corallum from which 
the living tissues had vanished. Other specimens show phenomena 
of fission, and others again have regenerated from a small part of 
a broken corallum. In a former paper (1923 b) I have described at 
length these phenomena in a large material of Fungia fungites. The 
specimens in the present material do not afford particulars greatly 
differing from those described in my former paper.
