Fig. 343,3a,b. *E. incerta (BILLINGS), syntype, Chazy., Que., Mingan Ls.; a,b, transv., long. secs., X3 (Sinclair, 1961). [The
genus is tentatively included in the Lyoporinae because, although the syntypes are described as too recrystallized to show original microstructure, the Eurasian species placed in it have radially fibrous walls with small septal trabeculae, the inner ends of which may project as spines into the lumen. It might, also reasonably, be classified in the Auloporida.]
