Description
A 'semi-slug' with a flattened, globular shell. The animal is pale grey with darker head and tentacles. It is large in comparison with the shell and cannot completely retreat into it.The shell is subglobose, somewhat smooth, pellucid and greenish hyaline in colour. The shell has 3 whorls that enlarge rapidly and are somewhat convex. The body whorl is wide and a little flattened below. The suture is wrinkled. The aperture is lunately rounded.[2] The umbilicus is very small.[3]
The width of the shell is 6 mm, the height is 3.5 mm.[2]
