a bank of stones and sand in the sea. Here I collected a great 
number of anthoblasts and free anthocyathi in all sizes, many of 
which were regenerated from fragments. Fungia cyclolites was the 
only species of the genus that occurred here, so that the anthoblasts 
cannot have belonged to another species, and moreover all inter- 
mediate stages between stalked young specimens and adult ones 
were collected. Besides these a great many specimens were procured 
by a native diver, also in the neighbourhood of Gelala, from depths 
of 1 to 4 meters. 
The material of this species from Amboina, though it was 
collected in a very limited locality, is comparatively variable in 
form. Especially the height is different in specimens possessing the 
same length, as may be seen in the following table, where the 
measurements are given of pairs of coralla that have about the 
same length.

In many specimens the whole of the upper surface is strongly 
arched, whilst in other ones only the central part of the corallum 
is arched and the marginal part is much less elevated (fig. 48). 
Sometimes the margin presents a sharp edge, especially in the 
younger specimens. In most cases, however, the margin of the 
corallum is broadly rounded and the septa continue gradually into 
the costae. In the smallest specimens the six primary septa are 
easily recognisable. Their size is larger than that of the others and 
they extend further towards the axial fossa. In the course of further 
growth the septa of the second cycle on both sides of the axial
