Zebinella townsendi

(Original description) The bluish white shell is of medium size and elongate conic.

They are marked by strong, well-rounded, slightly protractive, axial ribs, of which 16 occur upon the first, 18 upon the second, 24 upon the third, 26 upon the fourth, 38 upon the fifth, and 52 upon the body whorl.

In addition to the axial sculpture, the intercostal spaces are marked by well-incised spiral lines, of which about 22 occur on the penultimate turn.

The base of the shell is somewhat produced, marked by the continuation of the axial ribs which extend to the umbilical chink, and by 13 well-rounded, somewhat irregularly spaced, spiral cords which are not quite as wide as the spaces that separate them.

The parietal wall is covered with a thick callus which renders the peritreme complete.
