"This species varies very much in size .-mil color, no two speci- 

 mens being alike; the largest (somewhat bleached) one is totally 

 yellow except the peristome, the smallest is yellowish orange, with 

 while sutural zone, a dark apex and a few faint brown blotches 

 ranged in two rows on the upper whorls; a third full-grown speci- 

 men and a juvenile one are yellow with more or less green, disposed 

 in streaks on the last whorl, and have a white sutural zone; the full- 

 grown specimen has a yellowish apex and two rows of brown blotches 

 on the next whorls, which cease abruptly on the penultimate whorl; 

 the younger specimen has a dark apex and dark flames, of which 

 only a few are divided by a narrow white spiral zone ; the penulti- 

 mate whorl is partly brown-shaded. This species shows affinities to 

 many other species of the East Indian Archipelago, the upper whorls 

 of some specimens recall in mind A- contrarius Mull., the green whorl 

 resembles some varieties of A. furcillatus. They differ from every 

 known species by the uncommon development of the peristome, 

 which is most characteristic and suffices to recognize the species at 

 first sight " (Schepm.).
