Tricolia elongata ( Krauss, 1848)

Phasianella elongata Krauss, 1848: 104 , pl. 6, fig. 3. E.A. Smith, 1911: 313. Bartsch, 1915: 145. Thiele, 1925: 23 [57]. Turton, 1932: 172, no. 1223. Type loc.: ‘ In litore capensi ’ [on the shore of the Cape]; type material probably lost, none in SMNH ( Herbert & Warén 1998).

Phasianella tenuis (non Philippi, 1844, nec Michaud, 1829)— Krauss, 1848: 105.

Phasianella alfredensis Turton, 1932: 173 , pl. 40, no. 1227. Type loc.: Port Alfred, E. Cape; holotype in OXUM (M002773).

Tricolia elongata — Robertson, 1985: 21. Nangammbi, 2010: 131, figs 2.40–2.44. Marais, 2011: 52. Nangammbi et al. in press.

Not Phasianella (Tricolia) elongata — Dautzenberg, 1929: 528 [?= Phasianella solida Born, 1878 ].

Distribution. Southern Cape coast, from East London to False Bay; intertidal.

Notes. Records from Madagascar and Japan were based on misidentified and mislocalised material respectively ( Robertson 1985). The material that Krauss (1848) recorded under the name Phasianella tenuis (= Tricolia tenuis from the Mediterranean) was clearly misidentified. The dimensions he gave indicate that the shell he had before him was slender and that it was most probably a colour variant of T. elongata .
