Treatise on Invertebrate Paleontology (1953):

  • Zoaria generally slender, ramose. Zooecia with thick walls more or less fused in mature region; diaphragms straight. Mesopores and acanthopores commonly present.

Bassler (1911):

  • In this family, the amalgamate nature of the zooecial walls is most marked, in fact so much so that adjoining walls usually appear as completely fused together. Although the family is well represented in Ordovician strata, species with the most completely amalgamated walls, such as in Batostomella and Stenopora, are restricted to later Paleozoic rocks. Of the genera discussed in this work, Bythopora, Lioclemella, and Lioclema are typical Batostomellidae. Eichwalds’s Orbipora is referred to the family on account of its fused walls, while the new genus Esthoniopora is considered as a primitive type of Stenopora. Eridotrypa, although probably best placed in this family, is a somewhat aberrant genus having relations with the H. similis section of Homotrypa.
