In my matericil only thø Diascris-^ovva of this spøciøs is rcprc- 
sented. As I already pointed out in a former paper (1923 c) the 
costae of my specimens are on the whole less prominent than in 
the specimens figured by Doderlein. 
All stages of regeneration are found among the material. Many 
specimens consist chiefiy of a wedge-shaped fragment on the central 
part of which the first traces of new sectors are visible (fig. 64). 
This new-formed part enlarges itself in the course of development 
and usually differentiates into two or more separate lobes in each 
of which the perioherical parts of the septa diverge more or less. 
At last the corallum is composed of some almost equal lobes 
separated by deep furrows. Usually the parts composing the corallum 
seem to detach themselves from each other when the corallum has 
reached a certain size and afterwards each piece regenerates into 
a new Diascris-lovxn. Sometimes only one of three wedge-shaped 
fragments is separated from the others and traces of a new fragment 
can be seen in its place. 
The septa in each part of the corallum bend more or less 
towards the sides of ihe lobes; in some specimens they have a 
strongly curved course (fig. 56). 
In 'some of the larger specimens, especially in those from Banda, 
the furrows that separate the different wedge-shaped components 
of the corallum have almost completely fused, the corallum in 
general also being comparatively thick (figs. 59, 60). The shape 
has become nearly circular, only a few notches in the marginal 
region and a few ridges at the lower surface indicate the original 
sectors of the DiaserisAovm. There is much evidence that these
