second chamber, close coiled in one plane; wall calcareous, perforate, 

 surface smooth or variously ornamented; aperture formed by the

Cambrian to Recent. 



The Early Paleozoic records for this genus are fairly well substanti- 

 ated and seem to show that this calcareous group has arisen inde- 

 pendently of the truly arenaceous or agglutinated group.
