Among the fossils figured in the Silurian System (1839) is a cast of a dorsal valve of a brachiopod from Marloes Bay, named by J. de C. Sowerby Spirifer liratus. This form received more adequate description by Salter (1848) in the Memoirs of the Geological Survey, and in Murchison’s Siluria, and was later included under the generic name of Stricklandia, proposed by Billings (1859) for a certain section of the Pentameracea, and subsequently changed by him to Stricklandinia (1863). In subsequent descriptions, of which the most important are those of Davidson (1866), Angelin and Lindström (1880), and Schuchert and Cooper (1932), the form has always been referred to this genus.
