Upper valve darker shades of brown, lower valve whitish, sometimes yellowish, orange, or pink. Inner surface of lower valve white. Upper valve mottled with reddish-brown and dark-brown markings. Main figure shows external surfaces of lower and upper valves, next image shows internal surfaces of same vales, third illustration shows a lower valve (two vies) with pinkish external surface found by Kimberly Nealon on Bowmans Beach, Sanibel, on July 4th, 2016.
