The Truncatellre are characteristic of an assemblage of forms 

 which may be termed the land littoral fauna, other members 

 being Stenogyra tuckeri, Pujm pedicula, Pythia scarabwus, and 

 perhaps, Conulus starkei, and C. russelli. This littoral fauna 

 always inhabits, but is not invariably confined to, the neighbour- 

 hood of the sea beaches. The smallest islands which possess any 

 life at all are usually stocked by these forms, which appear to 

 range from Ceylon in the west to the Sandwich Islands in the 

 east, and to be limited north and south by the tropics. Within 

 these bounds they are associated with many widely different fauna?.
