‘Tuenre are three very distinct varieties of this Solarium. 
The English one, with only a few granulated ridges on 
the upper side, and the margin slightly prominent but 
relieved by a furrow on each side of it. The French va- 
riety, which has one prominent row of granules and many 
very minute rows on the upper side, the margin much 
produced and very finely crenated. And the Italian va- 
riety, of which the upper surface is beautifully orna- 
mented with many rows of conspicuous granules; the 
margin very much produced, deflected, solid; and so 
sharply crenated as to be almost dentated. In this va- 
riety the crenulations within the umbilicus are also very 
sharp and pointed.—The actual aperture is roundin all 
the varieties, and the characters above mentioned are 
liable to some variation. 
Very abundant in the Clay at Barton Cliff.
