1: basal half of pallial tentacles has opaque pigment; white, off-white, cream or, on large specimens, yellowish or orange.
2: distal-half fades to translucent.
Opaque basal parts often distinct from translucent mantle-skirt that they arise from so possible to confuse some with P. depressa; important to use pallial tentacles in combination with foot-colour/shell-length for identification.
