Spergo

Spergo is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.

==Description== The large, thin shell is nearly destitute of sculpture. It shows an unrecurved columella, a short, wide, straight siphonal canal, a wide shallow emargination representing the anal notch, and generally feeble anal fasciole, except in the very young. There is a sharp outer lip, unarmed aperture, and a sinusigera protoconch.
