I Distance between the apertures 0.30 mm. 



Measurement*. Width of zooecia including peristome _ 0.08 mm. 



Zoarial width-.. .__ 0.-26-0.28 mm. 



Our measurements arc smaller than those of the specimens from the Tertiary 

 formations of the environs of Paris. 



The characteristic of this species is that the distance between the apertures is 

 greater than the width of the segments. But to be certain of the determination 

 it is necessary to know the micrometric dimensions of the. type and the nature of 

 its ovicell, two features of which we are ignorant.
