Many examples of this splendid species were obtained. It is 

 notable for the depression of the inner whorls, which are frequently 

 concave.

About 75 specimens of this magnificent species were secured by 

 Mr. Stearns. They are very large, from 34 to 39 mm. diameter,

 4f times in length of shell ; peristome reflexed, whitish, slightly 

 thickened, not adnate ; superior lamella strong, extending to the
