Notes. Subsequent to my revision of the South African Solariellidae (Herbert 1987c), I have been able to examine the type material of Cyclostrema semisculptum and found that the specimens represent juveniles of the species previously known as ‘ Solariella ’ intermissa . The types of both taxa were from the same Valdivia station. As the earlier name, semisculptum has precedence over intermissa . The species discussed under the name Spectamen semisculptum by Herbert (1987c) represents an undescribed taxon (see Spectamen martensi above). The morphology of the shell and radula of this species (Herbert 1987c) strongly suggest that it is referable to Zetela rather than Solariella (cf. Marshall 1999; Williams et al. 2013).
