50 A MONOGRAPH OF 



suture, faintly elsewhere ; spire nearly flat ; suture impressed, narrowly 

 marginate ; whorls 3, the last depressed above, produced, rounded at the 

 periphery and below ; aperture diagonal, Innately ovate ; peristome 

 simple, sharp, right margin curved forwards, then gradually rounded to 

 the columellar, which is (generally) membranous. 



Diameter, greatest 0*55, least 0-45; height 0*17; aperture, 0*40 

 long, 0*35 broad of an inch. 



Habitat. — Generally distributed ; islands in Bass Straits ; also 

 Victoria, Australia. 



To be met with everywhei'e, both in dry as well as moist situa- 

 tions. It varies considerably in size, and specimens from Recherche 

 Bay approach F. Milligani in size and colour ( Legraiid). 



I have collected it high up Mount Wellington, at an elevation of 

 over 3000 feet. In Victoria it is abundant, especially in Gipps Land, 

 and exactly corresponds with specimens from this island.

Shell depressly-ovate, rather solid, polished, very glossy, translucent, 

 olive black ; spire convex ; whorls 3, second convex, last depressly- 

 rounded ; aperture more oblique than diagonal, Innately rounded-oval, 

 within coloured as without ; peristome simple ; right margin dilated 

 forwards, anterior regularly and columellar slightly arched. 



Diameter, greatest 0-83, least 0*60 ; height, 0-35 ; aperture, 0*45 

 long, 0*45 broad of an inch. 



Habitat. — Macquarie Harbour. 



This is really a beautiful and fine shell, with an extremely highly- 

 polished lacquered appearance. It is confined to the western portion of 

 the island. Cox remarks in " Monograph Australian Land Shells" that 

 it " resembles in a most striking manner very young specimens of Helix 

 Busbyi of New Zealand." In Australia the only species with any 

 resemblance to it is Helix attramentaria (Shuttleworth) from the Dande- 

 nong Range, Victoria. The likeness is far more noticeable in young 

 immature specimens of that shell than in fully developed ones ; then it 

 is at once seen that they are very distinct, although of the same colour 

 and peculiar texture.
