Crosseola striata is a species of small sea snail or micromollusc, a marine gastropod mollusc in the family Conradiidae.

It is spirally striated, with a raised, subscalar spire, a minute rounded apex, which is tabulated, with the extreme tip just visible, a tumid body whorl, and a small strongly bordered umbilicus.

Spirals—there are furrows broadish and square-cut, parted by flat raised surfaces of about twice their breadth.

The inner lip is regularly curved from the corner of the aperture to the point of the columella, which is arched, with a thin inner edge parting the aperture from the umbilicus and joining the outer lip, while round the umbilicus twists the strong marginal cord which runs out into a strong blunt tooth at the tip of the columella.
