Description. — Test free, consisting of a proloculum and long, undi- 

 vided second chamber, coiled in an elongated close spiral, wall com- 

 posed of sand grains and much cement, smooth; aperture, the open 

 end of the tubular chamber. 



The single species here included has a long, closely spiral test very 

 different from any of the preceding, and it seems proper that it should 

 have a different generic name.
