VARIATIONS OF SUBSTANCE OF SHELL. 
Var. solidissima Paulucci, Faun. Moll. Calabria, 1880, p. 119. 
Helix aspersa var. solida Westerlund, Faun. Moll. Extram., 1878, p. 133. 
Helix aspersa var. eburnea Baudon, Journ. de Conch., 1884, p. 239. 
Helix aspersa var. ponderosa W. A. Gain in litt. 
SHELL much thicker and heavier than the type. 
The sub-var. eburnea is described as of exceptional weight and thickness, and 
in the original locality as almost denuded of epidermis ; peristome thick, solid, and 
rather glossy, with a yellowish tinge, recalling the aspect of old ivory. 
It has been frequently remarked that this species tends to produce a thicker 
shell than usual when living near the seashore. 
Dr. W. A. Gain sent out shells about fifteen years ago under the name of var. 
ponderosa, which averaged about 35 mill. in diameter and 90 grains in weight.
