Lagena semilineata Wright, 1886

Fig. 3A, 3B Lagena semilineata: Wright 1886: 320 , pl. 26, fig. 7; Earland 1934: 161, pl. 7, figs 19, 20; Albani et al.

2001. Material examined: A27392.

Distribution: Inner shelf, littoral; Australia, Europe. Around South Africa from Kommetjie to Hermanus. Also recorded from samples off the coast of Namibia ( McMillan 1987 a).

Remarks: Differs from the Australian specimen described by Albani et al. (2001) in that it does not have raised costae on the test, and costae around the neck do not curve and do not extend the length of the neck.These differences in ornamentation can separate species.
