Helix (Nanina) irradiata. T. conico-globosa, tenuis, im- 

 perforata, albida, supra purpureo radiatim tessellata, lineis incre- 

 menti acutis confertim striata, subtus rotundata : spira anfr. 6 

 convexis, ultimo sub-angulato : apertura transversa, lunata ; labro 

 acuto, ad columellam incurvato, vix reflexo. Lat. ^, alt. f poll. 

 Hab. New Holland. , 



A singularly -colored Helix, in shape more like H. Cubensis 

 than any other which I recollect. The colors are arranged some- 

 what like those on Bulimus vexillum. 



Helix (nanina) eubricata. Testa globoso-conica, solida, vix 

 perforata, supra nitida, rufo-castanea, striis radiantibus gregatim 

 dispositis et striis volventibus decussata, infra glaberrima, livido- 

 castanea, ad centrum declivis : spira anfr. 6 convexis, amplis; 

 sutura submarginata : apertura semilunaris ; fauce livida ; 

 labro simplici, ad columellam reflexo, albo. Lat. 1, alt. -| poll. 

 Hal. Lebouka, Feejee Islands. 



In shape and size like H. zalela and H. irregularis ; but in all 

 other respects it is like H. velutina, Sowb., to which it is very 

 closely allied. Perhaps it is H. Nouleti, Le Guillou. 



Helix lurida. Testa globoso-conica, depressa, glaberrima, 

 nitida, livido-castanea, infra pallescens, ad umbilicum minutum 

 declivis : spira anfr. 6 convexis, radiatim et obtuse striatis, ultimo 

 prope aperturam subangulato ; sutura impressa, marginata : aper- 

 tura lunata, fauce livida ; labro acuto, ad umbilicum reflexo, albo. 

 Lat. 1, alt. £ poll. Hab. Feejee Islands. 



Groups with the preceding species to which it is very similar, 

 but differs essentially in the want of revolving stri.se, its carinated 

 periphery, and light-colored umbilical region. It probably be- 

 longs to Nanina. 



Helix calva. Testa tenuis, depresso-globosa, nitida, pallide 

 stramineo-virescens, arete umbilicata : spira anfr. 5 haud turgidis, 

 striis incrementi obsoletis ; sutura haud impressa, marginata : 

 apertura semilunaris ; labro simplici, acuto, ad umbilicum paulum 

 reflexo. Lat. |, alt. £ poll. Hab. Feejee Islands. 



Similar to the preceding, but smaller and lighter-colored, and 

 is plainly distinguished by its smooth, shining, rounded spire, 

 similar to the summit of H. Moricandi or H. lychmichus. This 

 must also be a Nanina.
