Olive shells

Olive shells (Oliva) are cylindrical, glossy snails that burrow in sand, in hundreds of colour forms that make them a specialist collecting field; Oliva porphyria, the tent olive of the eastern Pacific, is the showpiece. Pattern and gloss are everything, and specimens are graded on absence of chips at the lip. Fossil olives are common in Florida Pliocene shell beds.
