These two tiny slug species have small, almost covered shells. We have seen each species only once, years apart, but a dedicated search in and around rotting logs in the forest might turn up more.

The Warty Jumping-slug Hemphillia glandulosa, occurs on Vancouver Island, Canada, through Washington to west-central Oregon in the United States (slides 1 - 8). The Committee on the Status of Endangered Wildlife in Canada lists the Warty Jumping-slug as a species of special concern.

The Dromedary Jumping-slug Hemphillia dromedarius, occurs on Vancouver Island, Canada, south to the Cascade Range and Olympic Peninsula in western Washington (slides 9 - 13). Olympic National Park lists the Dromedary Jumping-slug among Endemic Animals of the Olympic Peninsula, and the Committee on the Status of Endangered Wildlife in Canada lists the Dromedary Jumping-slug as a threatened species.
