Variation: 
Colour varies form darker to lighter brownish. — As in ÅA. virginea, specimens 
of A. rubella, living on coral bottoms at Iceland and Finmark have a concave under- 
side and sometimes an elevated shape (var. elevata OÖDHNER 1910); but stages of 
transition from such extreme forms lead over into the type.
