- Abstract
A new species of the diatom genus Eunotia is described. The species, E. catillifera Morrow, is distinguished by the presence of fin-like plates, or transapical ridges, which alternate with the striae on the valve faces. This alga appears to be intermediate between the more typical Eunotia species and Semiorbis Patr. This observation suggests that Semiorbis hemicyclus (Ehr.) Patr. In Patrick and Reimer be returned to Eunotia hemicyclus Ralfs in Pritchard and that the use of the generic name Semiorbis be discontinued.
