This species closely resembles A. ampla, but is readily distinguished from it 
by a somewhat more slender form, stronger posterior tooth of the inner lip and 
broad spiral ribbings, being all of the same width and separated by narrower 
furrows. In perfectly well preserved shells the spiral ribbings are occasionally 
narrower than the furrows, but they are always very nearly of the same thickness 
among themselves. 
Localities—N, EB. of Karapaudy and Arrialoor; in softish, light coloured 
sandstone ; not common. 
Formation.—Arvialoor group.
