The finely decussate shell surface layer is translucent, and the thin underlying (middle) nacreous layer is visible as a pattern that is enhanced as light passes through fine interruptions of crossing radial and concentric elements of surface sculpture. A third non-nacreous layer is present interior to the middle nacreous layer in some of the Keasey shells. This is consistent with observations of complex crossed lamellar aragonite and other aragonitic microstructures in the interior layer of crenellids (
