Cocks, L.R.M. 2010. Palaeontology vol. 53, part 5, pp. 1155-1200 Caradoc Strophomenoid and Plectambonitoid Brachiopods from Wales and the Welsh Borderlands fig.4, plate 7, p.1183. Published incorrectly as A 40614. On p.1184 states that the specimen published as A 46015 in Williams (1955) is in fact A 46014. This is incorrect. The holotype figured by both Williams (1955) and Cocks (2010) is A 40615
