APLYSIA TRIGONA G. B. SOWERBY II, 1869

Aplysia trigona G. B. Sowerby II, 1869 : (206), pl. 4, fig. 11. Type locality: Not stated. Type: Probably lost, not found at NHMUK (A. Salvador, pers. comm.).

Remarks

Sowerby II (1869) described Aplysia trigona based on a shell of undetermined origin. The shell illustrated ( Sowerby II, 1869: pl. 4, fig. 11) is clearly rhomboid and different from the shells of other species here examined. Sowerby II (1869) indicated: ‘This species resembles Aplysia punctata in colour, texture, and convexity, but differs from them in its triangular form.’ Eales (1960) regarded A. trigona as a possible synonym of A. parvula , but with the available data we are unable to determine the identity of this species.
