Achatinella abbreviata, an Oʻahu tree snail, is an extinct species of colorful tropical tree-living air-breathing land snail, an arboreal pulmonate gastropod mollusk in the genus Achatinella.

Shell description[edit]

The dextral shell is ovate and somewhat ventricose with convex whorls margined round the upper shell. The shell has six whorls. The spire is rather short and obtuse at the apex. The columella is callous and twisted. Olive-yellow, with a black-brown line at the sutures; the lower part of the last whorl is very dark green and the apex is black.[2]

The height of the shell is 19.0 mm. The width of the shell is 10.0 mm.[2]


This species was endemic to the Hawaiʻian island of Oʻahu.
