DESCRIPTIONS OF EIGHT SPECIES OF AUSTRALIAN 

 AND TASMANIAN LAND AND FRESH WATER 

 SHELLS.* 



By John Brazier, C.M.Z.S. 



1. — Helix (Hadra) rufofasciata. 



Shell moderately umbilicated, globosely depressed, thin, minutely 

 rugosely granulated ; pale brown, marked with dark chestnut, 

 spiral bands, whorls 5, slightly convex, regularly increasing, the 

 last large and inflated in front, roundly convex, below the peri- 

 phery the chestnut band becomes broader and runs spirally into 

 the aperture ; base white with chestnut brown round the umbilicus, 

 aperture roundly lunate, slightly angular, peristome thin, acute, 

 margins rather distant, the columella margin dilated pai-tly over 

 the umbilicus, interior of aperture white or pink, the brown bands 

 are seen through the shell. 



Diam. maj. 12|, min 9f, alt. 7 lines. 



Hab. Tardea, 360 miles north of Adelaide, South Australia. 



This fine shell approaches near to Helix Cassandra, Pfr. ; it 

 differs very much from that species in having dark chestnut bands 

 above and below with a large broad white band on the base, and 

 chestnut brown round the umbilicus. I am indebted for it to Mr. 

 Waterhouse, the Curator of the South Australian Museum. 



2. — Helix (Hadra) Cookensis. 



Shell umbilicated, turbinately globose, thin, finely obliquely 

 striated (under the lens), rugosely granulated spirally banded and 

 lineated with deep chestnut lines and bands, spire conoid, whorls 

 5|, moderately convex, the last large and roundly convex, base 

 convex, umbilicus deep and narrow, aperture oblique, ovately 

 lunate, purplish within, peristome slightly reflected ; margins 

 approximating, the right partly descending, columellar margin 

 straight and broadly expanded partly over the umbilicus ; with 

 thin coating of callus across the body whorl to the upper part of 

 the peristome.
