Shell Description
Physically the shells are oval and cylindrical in shape. They have a well-developed stepped spire. Olive shells have a siphonal notch at the posterior end of the long narrow aperture. The siphon of the living animal protrudes from the siphon notch.
The shell surface is extremely glossy because in life the mantle almost always covers the shell.

“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
