 Hob. Lettui, Oahu. 



Shell elongately conical, solid ; whorls 7, slightly rounded, mar- 

 gined above ; aperture small, somewhat contracted ; lip subreflected 

 below, acute above, thickened within ; columella short, slightly twisted, 

 with an expanded callus partially covering a shallow small umbilicus ;

 mustelina, the variations in character, with different localities and a 

 peculiarity of habits in each, demanding their separation.
