Auger Shell 4.5ins x 6ins Oil on Board

I found a couple of shells I had once used as ornaments in the bottom of an old suitcase in the bottom of a cupboard in my bedroom. This according to my research on the Internet is an Auger Shell or Terebridae which is a kind of carnivorous sea mollusc/snail that lives on the bottom of the sea, particularly around coasts and hides in the sand where it lays in wait to kill other poor unsuspecting sea creatures mostly worms with a poisonous barb. Well I'm glad to say it wasn't laying in wait for me in the bottom of my suitcase. I thought this shell would make a nice painting. :)
