Their shell is irregularly covered with scattered swelling excrescences, 

 not, as in Murex, in longitudinal rows, but scattered all over the

 Triton variegatum, vulgarly called the Marine Trumpet (Fig. 289), 

 is a very large shell, which even attains a length of sixteen inches ; it 

 is enamelled with great elegance in white, red, and tawny-brown.

 Triton lotorium (Fig. 290) is of a reddish brown externally and white 

 within. The Triton anus (Fig. 291) is of a whitish colour, spotted 

 with red.

 spindle-shaped, spire many-whorled, canal long, operculum egg-shaped.
