Last week I introduced the Purplish Tagelus, commenting that its characteristic spatula-shaped shell is similar only to that of its sister-species, the Stout Tagelus, Tagelus plebeius (Lightfoot, 1786). This latter species is a bit larger, reaching in excess of 2 inches (instead of 1.5 in the Purplish Tagelus), and lacks the purplish coloration of the other one.
