Kurtziella plumbea is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

The suture is distinct, slightly appressed, the anal fasciole occupying the space between it and an angular shoulder.

The axial sculpture consists of (on the penultimate whorl, 15) narrow, sharp, arcuate ribs extending from the suture over the periphery, with wider interspaces.

The spiral sculpture consists of numerous minutely channeled grooves with wider flattish interspaces (the latter sometimes with a smaller median groove) covering the whole surface.

[2] This marine species occurs off California, USA, and Pacific Mexico.
