Description
The length of the shell attains 11 mm. It can be distinguished from ''
Diaugasma epicharta'' by its much larger size, say 11 mm. long, a wider
aperture, a shorter
spire, and a pink-tipped
apex. It is likewise semi-transparent, and the very delicate spiral striation across the
whorls is represented by the Reeve as sometimes evanescent altogether.

Distribution
This marine species occurs off the Philippines and Taiwan.
