Given a reference text about Conus episcopatus, describe the shell.

Context: Conus episcopatus common name the dignified cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.

Description
The size of the shell varies between 40 mm and 115 mm. The shell of Conus Episcopatus is elongated and has a high spire, which means that it has a tall apex. The shell is relatively thick and heavy, with a glossy surface and a series of raised ridges or ribs that run along its length. The overall shape of the shell is conical, with a pointed apex and a wider base.

The coloration of the shell can vary widely, but it basically has a base color of white or cream, with a series of darker or lighter bands, blotches, or spots that form complex patterns. The patterns can be quite intricate and unique, which is one reason why cone snails are prized by collectors.

Like all cone snails, Conus Episcopatus is venomous and uses its venom to immobilize and kill its prey. Venom is delivered through a harpoon-like structure called a radula tooth located on the proboscis of the snail. The venom of some species of cone snail can be highly toxic and dangerous to humans, and care must be taken when handling them.

Answer: The shell size ranges from 40mm to 115mm and has a base color of white or cream with series of darker or lighter blotches that form complex patterns.
