Gari stangeri, or the purple sunset shell, is a bivalve mollusc of the family Psammobiidae. It was first described by John Edward Gray using specimens collected by William Stanger.
Description It has a pink shell with radiating rings. The inside appears to be pink with a diffuse colour of white, and a white rim. The shell is oblong and around 2" in length when mature.
Etymology The generic name Gari is of uncertain etymology, with none listed in the original description. It is an ancient Greek hapax legomenon for a city in northern Afghanistan. The gender is normally considered feminine as it was originally combined with Gari papyracea.
Stangeri was named for William Stanger (surveyor).
