888 HELIX. 



Fariely'? Smaller, with three red bands on the body-whirl, and 

 two on the other. 



Helix marginata. Muller Verm. ii. p. 41. Gmelin, p. 

 3622. 



Inhabits Jamaica. Chemnitz. 



Shell about eight lines long, and fifteen in diameter, white, 

 with five depressed obliquely striated whirls, and a broad 

 brownish red band in the middle of each ; the umbilicus is 

 large and deep, and the aperture has a white reflected mar- 

 gin. In the Hist. Vermium, H. marginata is described to 



• be nine lines in diameter, with four whirls, of which the 

 body-whirl has three, and the others two red bands ; in other 

 respects the present shell answers to Muller's description, 

 but his meaning is rendered more obscure by his having com- 

 pared it with H. ijidistincta, and I cannot find that any He- 

 lix has ever been described under this name. 



ciCATRicosA. 5. Shell iimbilicated, keeled, de- 

 pressed, with the whirls convex, reversed, 

 and obliquely wrinkled ; base convex, and 

 the aperture effuse.
