Affixities. 
The inclusion of Cea JameUosa in this species appears justified 
hy the figures of d’Orbigny and the descriptions of Pergens. In 
Cea JameUosa, according to Pergens, the zooecia are “ more or less 
irregularly hexagonal,” and are from *25 to *3 mm. in diameter; 
and in Elea lamellosa the zooecia are lozenge-shaped, with rounded 
angles, and are from *24 to *26 mm. in diameter.
