Despite almost two centuries of palaeontological research on the Bohemian Cretaceous Basin (BCB) knowledge of cirripedes from the near-shore, shallow and pelagic facies remains poor. The first studies dealing with cirripedes from the BCB were published by Reuss (1844, 1845-1846), followed by Kafka (1885), Fritsch & Kafka (1887) and Fric (1911). Cirripedes from the BCB were revised by Withers (1935), with mention of collections of A. Fric, J. Perner and J. Sulc. Withers also listed 11 species of cirripeds (including two stramentids) from the BCB: Zeugmatolepas cretae (Steenstrup 1837); Calantica (Scillaelepas) conica (Reuss 1845); C. (Titanolepas) tuberculata (Darwin 1851); Cretiscalpellum glabrum (Roemer 1841); C. striatum (Darwin 1851); Scalpellum (Arcoscalpellum) angustatum (Geinitz 1843); S. (Arcoscalpelluni) maximum (J. De C. Sowerby 1829); Loriculina laevissima (von Zittel 1885); Stramentum pulchellum (G. B. Sowerby 1843); Proverruca vinculum Withers, 1914; Brachylepas fallax (Darwin 1851). Withers (1935: 162) suggested that Pollicipes striatus belongs to Cretiscalpellum glabrum. But the reexamination of the material revealed that the systematic position of P. striatus is different and actually belongs to Cretiscalpellum striatum, because its carina (Fritsch & Kafka 1887: 9, fig. 16) bears both longitudinal and transversal lines in contrast to carina of C. glabrum with only fine transversal lines. Most of these specimens are deposited in the National Museum in Prague, from which we examined and verified these original types: carina of Scalpellum maximum Sowerby var. bohemica Kafka from Kuneticka Hora (in Fritsch & Kafka 1887: 6, fig. 7A), now belongs to Arcoscalpellum maximum (J. De C. Sowerby); tergum of Pollicipes kosticensis Kafka from Kostice (in Kafka 1885, tab. II, fig. 4), now belongs to Cretiscalpellum striatum (Darwin); carina, scutum, tergum, rostrum, laterae of Pollicipes fallax Darwin from Lhota Uhfeticka (in Fritsch & Kafka 1887: 10. fig. 17 c, t, t, r) and rostrum of P. fallax Darwin from Chocen (in Kafka 1885, tab. III., fig. 2r), now belong to Brachylepas fallax (Darwin). Both scutum and tergum of Z. cretae were donated to the Natural History Museum in London (inv. no. 31673-4). Unfortunately, predominantly part of the original specimens from the NM collection, carinal plates (4 scuta and 4 terga) of Z. cretae and all specimens of Proverucca vinculum, which were important part of Sulc's fossil collection were lost at the end of The Second World War during bombing of historical building of the National Museum in Prague (Sklenaf, pers. com., 2012).
