This species is very well characterized by its salient visors and by 

 the great width of its marginal lamina. The ovicell figured by Waters 

 is marginal and not central. The central reticulations noted by 

 Harmer do not indicate at all the traces of the ovicell and we have 

 found them in other species. Perhaps it would be convenient to form 

 a special genus for this kind of ovicells if they were observed on other 

 species, notably in Lichenopora wilsoni MacGillivray, 1886. 



The visor of the tubes bears 2 or 3 long denticles, but we have not 

 observed visors as long as those figured by Busk in 1875. The tubes 

 are arranged in radial lines and not in fascicles.
