Lichenopora {Radiocavea) elliptica, Pergens, 1890. Rev. p. 382. 
Char. — Central area of irregular apertures, very large in propoition to the 
length of the radial bundles, of which there are about fourteen. The shape is 
elliptical in normal specimens. The apertures in the radii are usually biserial, 
with an occasional third aperture. (The shape in one of the specimens figured 
by d’Orbigny is irregular, it having grown around a cylindrical stem. Pergens 
remarks that some zoaria have the form of Paricavea.)

apertures are irregularly distributed, but with indications of the radial bundles, 
which consist of from three to five indistinct series.
