HETEROPOKA. 
201 
Aff. — MM. Thomas & Peron discuss the relationships of this species to genera 
ranging from Bijlustra and Flustrella to Entalophora ; and also to the species 
Heteropora constanti (d’Orb.) and Kodicrescis tuberculata (d’Orb.), both of 
which have abundant mesopores. Without sections showing the internal 
structure, even the family to which this species belongs is uncertain. It is not 
a Heteropora.
