Redescription of the type species of Latouchella Cobbold, 1921 (Mollusca) from the lower Cambrian of Comley, England

The type suite of the helcionelloid mollusc Latouchella costata, the type species of Latouchella Cobbold, 1921, is redescribed from the Lower Cambrian Comley Limestone of Shropshire, England. The laterally compressed, slightly asymmetric shell has a smooth dor sum and broad plications developed symmetrically on the lateral surfaces. Recognition of Oelandia Westergard, 1936, originally described from the Middle Cambrian of Oland, Sweden, on the basis of its asymmetrically developed plications seems therefore to be justified.
