928 HELIX. 



Shell about an inch in diameter, and the breadth exceeds the 

 length, but not in half the proportion of eleven to four, as 

 Born has described ; Linnaeus says it has only four whirls, 

 but a shell, which in other respects answers the description, 

 has five, and the umbilicus is large. MuUer has enume- 

 rated the following varieties : A. White, with a dorsal red 

 band ; B. White and spotless, with two dorsal red bands ; 

 C. White with milky spots, and two dorsal red bands ; D. 

 White, with three dorsal red bands ; E. White, with five dor- 

 sal red bands ; F. White, with two ventral and one dorsal 

 red band ; G. White, with two ventral and two dorsal red 

 bands; H. White, with four red bands, of which the upper- 

 most is very narrow ; I. White, with five red bands, of which 

 the dorsal are narrowest ; K. Uniformly yellow ; L. Yellow, 

 with a red band ; M. Pale flesh-colour, with marginal white 

 and red alternate bands ; N. Pale flesh-colour above, and the 

 base white, with red and white alternate bands ; O. White 

 with red spots, and six unequal red bands ; P. Grey spotted 

 with yellow, and three red bands.

above, with nearly six rounded whirls without uny keel, and 



the aperture lunated.
