Rem a rk s: As we have poimed out already (PILLAI & SCHEER, 1976), wefollow VAUGHAN (1918)
in rreating F. bululensis wirh F paliida. One of us (PILLAI, 1972) has shown that in a large suit of specimens
a gradation from those with smaller corallites and less sepra (forma bululensis) to the typical form
occurs.
EHRENBERG's type of F. rotuloSll is No _ 737 in Berlin Museum, it is shown by MATTHAI, 1914,
