Land' Shells from New Ouinen. 231 



leiitius accrescentibus, liiieis incrementi confertis, fortioribus 

 sculpta, anfr. ultimo infra carinam baud coacave impresso, subtus 

 striis concentricis vix visibilibus. 

 Diam. maj. 25| millim., min. 22, alt. 13; apertura 9 alta, 13 lata. 



This species is seen at a glance to be distinct from 

 N. Cairni^ which it resembles in colour and the width of the 

 umbilicus. The sculpture of the upper surface is quite 

 different. The close stride stop short just below the suture, 

 which is consequently margined beneath with a smooth 

 border. 



3. Rhysota Armiti. 



Testa perforata, orbicularis, carinata, supra saturate fusca, versus 

 apicem livido-purpurea vel rufescens, baud nitida, infra polita, 

 olivaceo-fusca, versus umbilicum paUidior, subflavida ; spira 

 depresse conoidea, ad apicem obtusa ; anfractus 6, lente accres- 

 centes, vix couvexiusculi, lineis incrementi oblique arcuatis 

 tenuissimis minute subrugulosis sculpti, ultimus oblique rugosus 

 et irregulariter indentatus, ad peripheriam acute angulatus, infra, 

 concentrice substriatus, lineis incrementi tenuibus ornatus, versus 

 labium inferius leviter inflatus vel saccatus ; apertura obliqua, 

 sublunata, saturate livido-fusea ; peristoma intus incrassatum, 

 carneum, margine columellari supra umbilicum breviter expanso 

 et reflexo. 



Diam. maj. 45 millim., min. 39, alt. 22 ; apertura 13^ alta, 23 lata. 



This species is allied to R. hercules of Hedley, but is 

 separable on account of its smaller size, the less elevated 

 spire, the slightly more acute keel, the less convex whorls, 

 the rather more distinct concentric striation on the lower 

 surface, and the peculiar inflation of tiie base. In colour the 

 two species are rather similar, but R. hercules is greener 

 beneath and has a rosy or pink peristome, which, in the 

 present species, is of a flesh-colour and not so pink. Slight 

 differences of sculpture are also discernible ; but these are 

 more readily seen by a comparison of the two forms. 



4. Helix (lladra) stirophora *. 



Testa depresse subglobosa, ad peripheriam obtuse carinata, late 

 umbilicata, saturate castanea ; spira convexe conoiden, ad 

 apicem obtusa ; anfractus 5|, convexiusculi, lineis incrementi 

 striati, ultimus antice breviter deseendens ; apertura late lunata, 

 obliqua, saturate fusco-purpurea ; peristoma undique mediocriter 

 expansum et reflexum, pallide purjjurascens, margine columellari 

 albo, latins expanso. 



Diam. maj. 34 millim., min. 28, alt. 23 : apertura 13 alta, 17 lata.
