Subglobular, flattened on the superior face; segments rather numer- 

 ous, four in the final convolution; sutures depressed; aperture a large 

 arched gaping orifice on the face of the final segment. Diameter,

 the last three large and inflated, the final one resting like a cap upon 

 one side of the shell; surface rough, originally bristly-spiny, as shown 

 by the unbroken spines in the aperture; principal aperture broad and
