Description
Amphidromus adamsii is a land snail species found in Borneo. It belongs to the family Camaenidae. There are two subspecies under this species, that is, A. a. adamsii and A. a. pictus. The former subspecies were characterised by the minute brown spot on the shell apex, while the latter did not has this character. The former subspecies has sinistral, large and thin shell, which measure around 23-38 mm in height and 14-20 mm in width. The shell colour of A. a. adamsii is white to yellow to pale ochre (with a pink hue), or olive-green, with or without wide blue-purple spiral bands. Meanwhile, the latter subspecies is almost the same as the former subspecies, except certain characters like the last whorl often slightly protruding, the shell height is ranged between 33 and 44 mm, while the shell width is ranged between 17 and 21 mm. The latter subspecies is more widespread than the former subspecies (which is more common on islands), with an elevation range between 0 to 1,400 m (Vermeulen & Liew, 2022).
