penultimate there are four such cords, and on the antepenultimate 

 three. Between and parallel to the spiral cords are fine, close, 

 microscopic hair-lines. Aperture narrow linear, with deep sinus 

 and prominent varix. Length 3 8; breadth 1*5 mm. 



Some variation in contour occurs, some individuals being 

 shorter and broader than others. The species is characterised by 

 its straight, narrow form, gradate spire, and strongly modelled 

 sculpture. Several specimens, from 5-10 fathoms, off Cairns 

 Reef.
