Hope Island off N end Vancouver Island, British Columbia. Diagnosis. Shell 20-40 mm, coniform with straight sides, umbilicate, columellar denticles very weak; early whorls flat-sided, finely striate, later whorls slightly rounded with impressed suture, some specimens sculptured with oblique rugose ridges; basal angularity sharp or slightly rounded; base smooth or with fine spiral grooves, evenly sloping into broad, funnel-like umbilicus, not bordered by spiral cord; juvenile shell gray with white mottling at periphery; mature shell purplish brown to orange, sometimes with alternating light, dark zones, often with row of lighter spots beneath the suture, color of base lighter. Distribution. Chicagof Island, southeastem Alaska to Puerto Santo Tomas, Baja California (32° N). Chiefly sublittoral on Macrocystis and other brown algae in northern California; Common at low tide in southeastern Alaska. Remarks. Brightly marked juvenile shells are common. There are few records from southern California, although large specimens have been collected on kelp at Puerto Santo Tomas, Baja California, an area of cold- water upwelling. Tegula pulligo has the general appearance of T. montereyi, which is easily distinguished by a strong columellar dentition and a spiral ridge inside the umbilicus.
