 umbilicata ; anfractibus 5, quorum duo apicales heves, mamillati, vitrei, 

 cseteris apud suturas paullum excavatis, ultimo spiraliter septem-carinali, cari- 

 nis duabus ad peripheriam quam maxime conspicuis, undique longitudinaliter 

 arctissime et oblique costulatis, costulis supra coronulatis et gemmatis, regione
