The type form has the bands interrupted; in the variety swzf¢zz they are continuous 
and almost confluent, recalling a dwarf A. dugudris. From the variety swz/tzz, given a 
fair number of specimens, we may pass by slight variations up to a nearly white shell 
with hardly a trace of banding. One specimen is light yellow and almost unmarked 
except the latter half of the last whorl, which is strongly banded with dark brown (Plate 
XI. figs. 6, 7). The general brown colouring is more persistent in the variety than in 
the typical form. The variety /fordeszana is somewhat more elongate and slightly 
differently banded and coloured.
