|The Rusty Oahu Tree-Snail is
one of the most colourful species in its genus, some shells are
amber-coloured, brown, green or orange, some are plain, others are striped
with green or orange.
The species was endemic to the Ko'olau Mountains on O'ahu, where it was found in several valleys, including the Makiki Valley and the Manana Valley.
At the beginning of the 20th century, when the species had become very rare, some specimens where transplanted to the island of Kaua'i, the neighbour island of O'ahu, where the last living individuals were found in the year 1948, and finally the last, of course empty, shells in the year 1973.
The last live specimens of this species were found in the year 1965 on the island of O'ahu - in an area where the introduced Rosy Wolfsnail (Euglandia rosea (Férussac)) was found as well.
