This species is separated from the following by the plain coloration, 

 without longitudinal markings. It frequently attains much greater 

 size than the measurements given above indicate ; Kiener's " T, 

 lividus " measuring 38 mill, in length.

Shell imperforate elongate-conic, pointed, exactly like C. badius 

 in contour ; polished, purplish-pink, darker toward the apex, with 

 longitudinal zigzag or flexuous white lines or stripes. Aperture as in 

 C. badius. Alt. 30, diam. 14 mill.

Exactly like C. badius in form and texture, but differing in the 

 longitudinal white lines. T. fulmineus Kiener, is founded on a speci- 

 men with very numerous oblique lines (fig. 12). The name lineatus 

 of Lamarck has priority for this species, and is not preoccupied in 

 'Cantharidus. I follow Fischer in retaining Philippi's name, how- 

 ever, as there is a lineatus in both Monodonta and Trochus s. s., both 

 bearing date anterior to the present species.
