Boonea impressa

Boonea impressa, common name the impressed odostome, is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

[2][3] The preferred host of this ectoparasite is the eastern oyster Crassostrea virginica.

[4] The thick shell is opaque and grows to a length of 6.7 mm.

The teleoconch contains seven flat whorls with a deep suture.

The body whorl has 15 revolving lines, the upper ones more distant, about four lines on the next whorl, the number of lines diminishing on the upper whorls.
