The type form has the bands interrupted ; in the variety swiftii they are continuous 

 and almost confluent, recalling a dwarf A. lugubris. From the variety swiftii, 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 

 XL figs. 6, 7). The general brown colouring is more persistent in the variety than in 

 the typical form. The variety forbesiana is somewhat more elongate and slightly 

 differently banded and coloured.
