mens. On the body the direction of the spiral is always that of a 

 left-handed screw, whilst on the neck it takes the opposite direction. 

 In the solitary ' Gazelle ' specimen figured by Dr. Egger the spiral 

 on the body of the shell is represented as being right-handed. 



The tendency of L. striata to have its strife arranged obliquely 

 has long been noticed, but hitherto no one has considered it necessary 

 to give the variety a distinctive name. In this matter there is no 

 general rule laid down, each author being guided by his own judg- 

 ment. It would probably be wiser not to create new names for these 

 trifling variations, bnt where the names exist there cannot be any 

 great harm in making use of them. 



The 'Gazelle ' Station is West Australia.
