(These differ from the type in being less elevated, smoother and 
somewhat shining, in having a larger umbilicus; and in the aper- 
ture, which has the inner lip slightly or often not at all developed, 
and the outer smooth and reflexed, the whole a bright reddish 
orange. The outer lip of the type is little reflexed and generally 
lamellar, the border is usually straight at its upper part; in the 
var. it is invariably bent back. Were this not such a variable spe- 
cies, Mr. Simpson thinks it should receive a specific name).
