These two cone shells came off fishing boats working in the Indian Ocean or Andaman Sea. They were purchased from the boat in Phuket Thailand.
Any help in identifying them would be appreciated.

Those are called cones shells
Hey bruceMC,
I could be wrong about this but I have some idea for the cone shell that appears to be an orange colour from the photo you've provided. I think it might be "Rhizoconus rawaiensis."
I'm not sure about the other one yet.
I hope I helped a little bit. If you type in that species name into google images you may find that the pictures that come up greatly resemble your beautiful cone!!!
Good luck with your further identification endeavours!
