« Testa perforata, alte-globuloidea, solidula, calcarea, fortiter 
oblique striata, nitidiuscula, alba. Spira obtuse conoidea; summo 
acute prominulo, fusco-corneo; sutura vix impressula. Anfr. 6, 
primi planiusculi, lente descendentes; ultimus rotundatus, for- 
pressed lines, sometimes obsolete and most persistent on the under side. 
Color beautifully mottled by cloudings of white and brown, irregularly 
disposed but having a tendency to disposition in an oblique radiating 
manner; the brown sometimes running together so as to produce imper- 
lect revolving lines; a little above the middle of the shell is a zone of 
darker brown, with usually a lighter band below, broken and irregular 
by the white patches and specks.» (G.)
