Kurtzina beta is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

[1] (Original description) The small shell is yellowish, with a short, pale siphonal canal.

From the distinct suture the surface slopes flatly to the subangular periphery, the rest of the whorl is rounded.

The spiral sculpture consists of uniform fine threads with narrower interspaces over the whole surface.

The axial sculpture consists of (on the body whorl 15) narrow rather sharp ribs with much wider interspaces, obsolete behind the shoulder and on the base.
