AUSTRALIAN LAND SHELLS. 99 



inflated; apertute diagonal, nearly round; peristome thin, expanded, 

 columellar margin straight, at its lower part forming an angle out- 

 wardly, margins closely approximating and joined by a thin callus, 

 umbilicus half covered by the columella. 



Diameter, greatest 0-62 ; least 0*45 ; height 0'40 ; aperture 0-30 broad, of 

 an inch. 



Habitat. All along the N. E. Coast of Australia and its islands, on 

 leaves of trees and bushes. MacGillivray. 



Of this species, which occurs also in India, the Philippines, Java, &c, 

 I believe the pure white variety is the only one which has yet been 

 observed in AustraKa.
