It is a very variable species. Some individuals are almost 
orbicular, others are extremely oblique, some have the radial 
sculpture very valid, others obsolete. The epidermis may 
be smooth, silky, and uniform, or disposed in marked con- 
centric fringes. The brown colouration may be very deep’ 
and general, or only in certain parts, or nearly absent. But- 
any attempt to separate into different species is vain.
