Six or seven (usually sc\.cn)rounded ribs similar to those of Ilatt~sl~~s onyx. Signs of tapering atlower end.The tube differs from H. onyx by being straighter, by sho~ving lesssigns of tapering, and hy often having seven ribs. Tt has many of theeharaeteristies of IT. protoonyx Richards (from the Eutalr. or Tusealoosaformation of Alabama), but is much larger. It is also n~neh largerthan II.
