This columbellid is common under rocks on pinnacle and seaward reefs. Like other columbellids, the shell varies somewhat in color, and according to these photos, so does the animal. The one in the first few photos below has a lighter colored shell, fairly close spaced brown dashes at the sutures between whorls, and a mostly white animal. The last few photos show a darker purple shell with slightly wider spaced brown sutural dashes and a white animal with extensive brown patches.
