Description
The shell grows to a length of 13.4 mm. This species  is  closely  related  to  Turbonilla dalli,  but  is  more slender,  longer,  with a more  pointed  apex, and  smaller  protoconch. The less  convex  whorls of the teleoconch are  more  numerous  ribs  and the aperture is  more  elongated. The suture is well  marked.

The projecting whorls of the small protoconch are transverse  to  the  axis. The 12 whorls of the teleoconch are slightly convex. There are about 20 transverse ribs. These are rather  stout,  nearly  perpendicular, and rounded. They are separated by  about  equally  wide,  deep,  concave  spaces terminating  at  the  periphery  of  the  body whorl  in  clean-cut  ends. The base of the shell is rounded, and smooth. The aperture is squarish,  somewhat  expanded below and with  rounded  angles. The inner lip is thickened, and  reflected. The entire surface is covered  by  very  fine,  microscopic  striae.
