Shell imperforate, broadly conoid, white, diaphanous, opaque, shining, granular on the surface, whorls five, gradually increasing in size, flat, last sharply angled at the periphery, pinched and everted at the peristome, reflexed at the insertion ; base flat; peristome bright-pink, lunately elongated, margins approached, everted and beaked at the center; aperture white within.
Diam. greatest 1*10 ; least 0.84; height 0'80 of an inch.
This fine species is in the Hargravesian Collection in the Australian Museum ; it is the same kind of shell as Helix Louisiadensis of MacGillivray, but is a larger species, easily distinguished from that species by its white diaphanous aspect, light-pink peristome and by the absence of the characteristic oblique fine striae on the surface of the whorls.
