Turris pulchra is an extinct species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.[1]

Description

Measurements of the shell: 20.0 mm x 6.5 mm.

(Original description) The fusiform shell contains nine whorls. The first four are turbo-form and smooth. The others are sharply angulated by a shoulder a third of whorl below the suture. They are decorated by twelve to fourteen subequal spiral lines which are slightly nodose where the fine sinuous axial ribs cross them. A beaded sutural collar occurs just below the indistinct suture. The aperture is elongate with its greatest width above, narrowing below into a slender siphonal canal. The outer lip is thin. The inner lip is slightly calloused.[2]

Distribution

Fossils of this marine species were found in Eocene strata in Oregon and Washington (state) , USA (age range:40.4 to 37.2 Ma)
