Extract

The micromorphic brachiopod genus Gwynia was established by William King (1859) on the basis of specimens described by Gwyn Jeffreys (1859) from the coast of Normandy and Belfast Lough. Additional, unpublished records of the genus from Larne and Portrush, collected by Dickie, Hyndman and Waller during the 1850s, were the last sightings of the taxon around Ireland (Massy, 1925). Despite the distinctive characteristics of the genus, Davidson (1861, p. 39) considered it had yet to be sufficiently determined whereas others (see Brunton and Curry, 1979, p. 46) have suggested the genus may be an immature form of Argyrotheca cistellula (Searles-Wood) with which Gwynia often co-occurs. However, that species is consistently transverse with marked exopunctae.
