TASMANIAN LAND SHELLS. 39 



aperture almost linear-lunate ; labrum thin, obliquely produced towards 

 periphery and slightly inflated, forming a narrow groove at the suture ; 

 angle of periphery faintly dilated into an obsolete keel. 



Diameter, maj. 1*25 mil, min. 1*15 mil. ; height, 0*3 mil. 



Hahitat. — Inyforth Creek, Surrey Hills, on trunks of dead trees, 



under moss, and in the deep shade of myrtle and sassafras 



folia/je — Fagus Cunninghanii and Atherosperma moschata. 



Kare. 



Only four specimens of this unique little shell obtained. It 



approaches H. Barrenensis (Petterd) in size and form, and R. Luckmani 



(Brazier) in colouring and sculpture. The colouration also approaches 



H. mimosa. 



61. — Helix ( ) Otwayensis — mihi. 



Quarterly Jour. Con., 1879. 



Shell small, imperforate, thin, orbicularly-depressed, pale chestnut 

 colour, finely, closely ribbed throughout, interstices minutely decussate ;. 

 spire almost flat, apex smooth ; whorls 5 J, convex ; suture much im- 

 pressed ; last whorl rounded, base convex, striae as above ; aperture 

 ovately-lunate ; margins distant, joined by a thin, shining callus ; 

 columellar margin slightly thickened, peristome simple. 



Diameter, greatest 2, least 1 J ; height, 1 mil. 



Habitat. — Cape Otway scrubs, Victoria, Australia. 



Variety a. — Alpina — Exactly same as typical specimens from Vic- 

 toria, but much larger. 



Habitat. — Surrey Hills. 



A pretty little shell allied to H. sericatula from New South Wales 

 and H. limula. ''Two specimens obtained among the collection made 

 by T. K. Atkinson and myself in the vicinity of Surrey Hills, nearly 

 2000 feet above the sea level. It is nearly twice the size of its Victorian 

 representative, and the sculpture is proportionately coarser. On this 

 account, and as it is new to Tasmania, I propose alpina as the name of 

 the variety. This adds another to the number of species common to 

 Victoria and Tasmania, and will be interesting to those who are investi- 

 gating the distribution of our island fauna" {R. M. Johnston). 



62. — Helix ( ) Bischoffensis — C. E. Beddome. 



Pro. R.S.T., April, 1879. 



Shell imperforate, flatly globose, whitish brown, very finely striated, 

 the striae being crossed with very fine hues, giving the shell a gi'anulated 

 appearance; spire roundly depressed; whorls 6 J, slowly increasing,
