I checked out the flags. I don't know what the heck the East New Britain flag is supposed to mean. It looks like a picture of two masks to me, but I don't see any shells. The shell on the West New Britain flag looks like a Charonia tritonis to me. The Travancore flags shell is a Turbinella pyrum, and for the Turks & Caicos it is Strombus gigas. So there.
