According to Abbott (1954), this is a species of the open coast. The background colour of the body varies from a translucent brown to translucent green with milky yellow spots, which are also visible on the mantle which can be seen through the trasparent shell. White mottling can also be present of the parapodia. It grows to at least 18 mm in length.

The shell, like most of the genus is thin, and fragile with a sunken spire. It is transparent to translucent and yellowish-green in colour.
