It progresses by raising its head, extending the body, and placing the posterior part of the foot down iu the form of an arch, lands its body gradually from the head ; and this arch thus appears to recede until the caudal extremity is reached. Like N. 1 vitrinina, it cannot at first recede into its shell; and like Vitrina strangei of Australia, it leaves mucus in its track of a brick-red colour. Hub. Taviuni." (Liardet.)

Exp., Shells, p. 29, fig. 66 ; Gray, Cat. Pulm. p. 129; (Hemiplecta) II. & A. Adams, Gen. Moll. ii. p. 223. So far as known, this species is restricted to Viti Levu and Ovalau Islands, where it is not uncommon beneath decaying vegetation in forests. It may be distinguished by its large size (25 to 30 millim. in diam.), dark chestnut-colour, globose-turbinate form, shining surface, and chiefly by the spiral impressed striae on the body-whorl. 2.

Nanina vitiensis (Xesta), Pfeiffer, Vers, p. 120. Eurypus cascus, Semper, Phil. Landmoll. i. p. 37, pl. 1. fig. 17. This species, like N. nouleti, is confined to Viti Levu and Ovalau. Like all the Viti species, lives beneath decaying leaves and under rotten wood. A rather solid, subconoid, more or less depressed, smooth, shining species, of a pale corneous colour, sometimes with a slightly ruddy spire and perforated base. |
