464 ISANDA-CAMITIA, 



A compact, depressed little shell, with diamond-shaped aperture, 

 showing in fresh specimens a slight trace of pearl within. Adams 

 describes the color as spotted with brown in transverse series, with 

 transverse whitish lines, and a wide subsutural white band. The 

 coloration is very inconstant, as the figures on pi. 59 (copied from 

 Smith) show. The columella is straight, a trifle expanded above, 

 connected with the uppel* lii^ by a thin parietal callus.
