166 MR. A. GARRETT ON THE TERRESTRIAL [Feb. 15, 



" Animal red ; a protuberance on the back rests against the shell 

 anteriorly. It progresses by raising its head, extending the body, 

 and placing the posterior part of the foot down in 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. ? vitrinina, it cannot at first recede into its shell ; and like 

 Vitrina strancjei of Au'^tralia, it leaves mucus in its track of a 

 brick-red colour. Ilab. Taviuni." {Liardet.)

So far as known, this species is restricted to Viti Levu and Ovalau 

 Islands, where it is not uncoamion beneath decaying vegetation in 

 forests. 



It may be distinguished by its large size (25 to 30 millim. in 

 diam.), dark chestnut-colour, globose-turhinate form, shining sur- 

 face, and chiefly by the spiral impressed striae on the body-whorl.

Eurypus cascus. Semper, Phil. LandmoU. i. p. 37, pi. 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.
