Pleurotoma (Drillia) watsoni E. A. Smith, 1891 (original combination) Awateria watsoni is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

(Original description) This small, white shell has a short fusiform shape.

The upper slope of the six whorls is comparatively smooth, exhibiting only a few (about 4) faint spiral lirae, and the lower portion and the greater part of the body whorl are covered with a distinct cancellation, the points of intersection of the oblique and transverse lirae being rather acutely nodulose.

The arcuate lip is prominent.

[2] This marine species is endemic to Australia.
