They vary frora pure white to trifasciate with rose or livid brown, 

 usually taint and nebulous. The height of the spire, elevation of 

 tin 1 nucleus, and extent of shell covered by the punctate line.-, vary 

 in the different specimens. Usually the spire is rather elevated, 

 nucleus somewhat depressed, and the punctate grooves cover about 

 half of the la.st whorl. There may be one or several siihsutural 

 lines, the middle of the whorl is generally smooth and free from 1 

 and the anterior part crowded. .The northern ones are variegated 

 like those from the Antilles, but the latter are more frequently 

 bright colored. The very young, like those figured by Adams and 

 Orbigny, are usually white or translucent. The colors, when banded, 

 are nearly always rather nebulous, and the number of bands never 

 exceeds three, the anterior one most often absent. The shell is 

 is always thin, and often nearly translucent. (Dalf).
