 It has been suggested that this is a variety oi A. nubilosa Mighels, but the present 

 species is a more slender shell with much flatter whorls.

Morelet's original series, now in the British Museum, consists of three specimens, 

 one belonging to this species, and two to A. assimilis Newc. ; his diagnosis however 

 refers to a form with only one columellar plait. From Mr Perkins' long series, it 

 appears that the upper plait is variable and sometimes becomes obsolete ; in one 

 specimen, which has received an injury, both plaits are dwarfed so as to show only as a 

 slight thickening of the columella.
