Tenagodus bernardii Mörch, 1860

Description: Whole shell very loosely coiled; sculpture with broad, low, longitudional threads along most of the length of the shell. Slit closed for most of the shell length, open as a smooth-sided slit for last few centimetres. Aperture circular, lip thin and irregular. Interior smooth, white and polished. Colour white.

Size: Large specimens 180 mm in length, tube external diameter 6 mm.

Distribution: Indo-West Pacific. In eastern Australia, as far south as Sydney.

Habitat: "Aggregated in sponge" (type description).

Comparison: With the small number of specimens available I am unable to separate this species from T. cumingii, apart from this being even more loosely coiled. I rely on the expert identification of the Museum collection for its presence in NSW. The original description indicates that this species is distinguished by very long hairs on the operculum, but otherwise resembles other species from "l'Indie orientale".

Remarks: This species has not previously been recorded from NSW. The Australian Museum holds one lot from Sydney and one from Collaroy, NSW.
