28. Columbella (Anachis) pura Verrill. 



This shell resembles the shallow water species Col. zonalis Linsl. in form, except 

 that it is somewhat shorter and stouter with the whorls more convex, the columella 

 raore excavated, the apertura a little wider, and the canal slightly beut back at the tip, 

 but the shell is translucent and glossy, and the colour is pure white or pinkish white, 

 except near the apex, where it is tinged with pale brown or pink, in fresh specimens. 

 The surface is smoth, except slight lines of growth and a few faint spiral lines on the 

 canal anteriorly. The nucleus is distinctly larger than in the typical zonalis.
