I suspect Emilio knows... but for those who don't, yes, the
selenizone is named for the "new-moon"-shaped growthlines most
selenizone-bearing gastropod shells produce where they curve around
the end of the labral slit or notch. Living taxa: Pleurotomariidae,
most Scissurellidae, slit Fissurellidae, some "turrids". The
selenizone is the track left by the slit as the shell grows by labral
accretion, and is often bounded by raised cords or lirae.
