Aclis is a genus of small sea snails, marine gastropod mollusks in the family Eulimidae.^[1]

The shell is minute, elangate- turreted like Turritella. They are usually thin and translucent. The protoconch is slender and consists usually of two whorls. The remainder are convex and well-rounded. The suture is prominent and well-impressed. The shell is usually spirally striated. The apex is sinistral. The aperture is oval. The thin outer lip is prominent. The axis is slightly rimate. The base of the shell is rounded. The shell has an operculum.

The animal shows a long retractile proboscis. The slender tentacles are close together. They are inflated at the tips. The eyes are immersed at the bases of the tentacles. The operculum lobe is ample. The foot is truncated in front.^[2]
