When living, the central part of the test of this species is 
usually of a rose or red-brown tint. The specimens from the 
lagoon are invariably white, and those from near the middle of 
the lagoon are discoloured and yellowish-brown. This leads one 
to conclude that these and many other forms are not actually 
living in the lagoon, but are carried in by ocean currents. 
The depressed variety sometimes found accompanying the 
typical forms is here very rare.

The specimens from the lagoon are typical but rather small. 
The species is chiefly known from the coral-reefs of the islands 
of the Pacific, and it also occurs off Mauritius.

It is very probable that the examples found in the lagoon have 
floated in by the action of currents, especially since this form is
