Abstract
The genus Chasmazoon is introduced for Cellepora abdita MacGillivray (1895) from the Tertiary of Victoria. Chasmazoon abditum has colonies capable of both an encrusting and free-living mode of growth, and the latter were probably anchored by basal rhizoids. The large, simple orifices and striated, peristomial ovicells of C. abditum are distinctive, and Stichoporina parvicapitata Canu & Bassler (1935), which has closely similar characters, is considered to be synonymous.
