AUSTRALIAN LAND SHELLS. 67 



convex below, with a narrow reddish-brown band under tho 

 pheriphery, very slightly descending in front ; aperture diagonal, 

 lunately rounded ; peristome expanded, reflected, thin edged, mar- 

 gins not approaching, columellar margin thicker and nearly conceal- 

 ing the narrow umbilicus. 

 Diameter, greatest - 80 ; least - 70 ; height l - 00 of an inch. 



Habitat. Night Island, N. E. Coast of Australia, on trees. Mac- 

 Gillivray and Edwards. 



Several mistakes regarding identity and locality between this and II. 

 Gdertneriana have been made by Pfeiffer, Forbes, Reeve, and 

 myself. This shell, I am enabled to state with certainty, is not from 

 Port Essington as originally stated. It was first found in the locality 

 indicated by me during the voyage of the Beagle, and subsequently 

 during that of the Rattlesnake, and since then it has twice been col- 

 lected there for me in abundance. It is curious that this fine shell 

 should apparently be completely confined to one little island, the dry 

 portion of which is not more than a quarter of a mile in length.
