Affinities. 
This small species is much narrower and higher in proportion to 
its diameter than the t} 7 )ical members of the genus. It is a small 
form and probably grew on a soft calcareous mud, in which it was 
probably partly buried. It, however, agrees essentially with 
Discocytis, as the apertures open in groups on the top of blunt, 
irregular projections around the upper margin of the zoarium.
