Lora quadra Dall, 1919 (original description) Oenopota quadra is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

(Original description) The short and stout shell is white.

The anal fasciole is narrow, excavated, and finely spirally striated.

The axial sculpture consists of (on the body whorl about 18) stout nearly vertical ribs angulated at the edge of the fasciole, forming a narrow shoulder, but without a limiting cord, with usually narrower interspaces and obsolete on the base.

[2] This marine species occurs from the Aleutian Islands to Puget Sound.
