The material here dealt with includes: — I. Seven vertebral centra ofScanisauruscf.nazarowi(Bogolubov 1911), from the L. Campanian of the island of Ivö. The centra seem to belong to the same skeleton as a previously described series of centra (“series II”; cf. Persson 1959, p. 452; Pl. 9). — II. A vertebral centrum referred toScanisaurussp., from the clay of Åsen in the parish of Näsum (? U. Cretaceous). The locality is famous for its richness in fossil drift-wood, but with the exception of plesiosaurian remains (Persson 1962, p. 149) no animal fossils have been found there. — III. Some plesiosaurian bone fragments from a 51 m deep borehole in Ivetofta near Bromölla (L. Campanian).
