Family Cancellariidae

Shell size to 25 mm; shell turreted, slender. Surface finely cancellate. Varices present every 2/3 whorl. Aperture elongate, narrow. Parietal shield well-defined, raised. Color gray with brown markings.

Shell size to 30 mm; shell stocky, solid, apical part of whorl with strong, flat shelf. Side of whorls with 3−5 beaded cords. Umbilicus very deep, funnel-shaped. Color light-brown to light-orange to yellow. This species is known mostly from shells collected through offshore dredging. The "yellower" specimen was collected by Michael Gillmore (Michael G-by-the-Sea) on Christmas Day, 2014 on Blind Pass, and the lighter-colored specimen by Lois Dunnam on December, 2003, after a winter storm, on the beach off West Gulf Drive’s Beach Access no. 7, both on Sanibel Island.

Shell size up to 48 mm; shell solid, with 4-6 whorls slightly angled at shoulder. Typically sculptured with axial ribs and spiral cords of about same thickness, giving shell reticulated appearance. Suture well-impressed. Aperture relatively large. Columella with 3-4 strong pleats. Color white to pale orange with bands of rust-brown. Albino shells are not uncommon in Southwest Florida. The picture of the living nutmeg was taken by Amy Tripp on Kice Island, Collier County, in 2010. The juvenile shell, measuring about 3 mm, was collected by Kimberly Nealon on Captiva. The protoconch, or larval shell, can be seen on top of the juvenile shell.
