Striated Tree-Snail (Partula levistriata)  

This arboreal species was described in 1956.  

The Striated Tree-Snail is apparently known from a single specimen that was collected in the Ereeo valley, where it lived sympatrically with another tree snail species that is now extinct, the Cuneate Tree-Snail (Partula cuneata Crampton.).  

The shell was yellowish corneous and was decorated with irregularly spaced transverse strigations of warm brown. The lip was white and shining. [1]
