Echinofulguridae

The family comprises three genera per WoRMS, although the source describing Archefulgur also divides it into three subfamilies (see synonyms below).^[1][2] The author who named them, Petuch, diagnoses them as "small-to-medium sized gastropods with inflated, pyriform or fusiform shells, most often ornamented with two rows of spines or knobs, one around the mid-body and one around the shoulder; some species have only a single row of spines around the shoulder; shell surface smooth and silky or sculptured with numerous very fine spiral threads; siphonal canals elongated, narrow, separated from the body whorl by a distinct constriction; siphonal canals often ornamented with strong spiral cords or a single large scaly ridge; spire whorls generally elevated, protracted, or scalariform, most often ornamented with one or two rows of spines; parietal region glazed; apertures wide and flaring; protoconchs rounded, composed of two whorls."^[2]
