The size of the shell varies between 11 mm and 17 mm. The imperforate, thin shell has a conical shape. it is pale rose colored. The upper whorls are plane, and tricingulate. The upper cingulus is beaded, the second and the third are smooth. The body whorl is obtusely angled and encircled by 5 cinguli. The base of the shell is a little convex, with 6 cinguli. The aperture is quadrangular. The columella is a little oblique, cylindrical, scarcely truncate, but sensibly passing into the base.[3]

gollark: Or the ability to write text into unused sections of configuration files, assuming this preserved the syntax in question.
gollark: People would randomly be ambushed with GTech™ GCryptocurrency™, which could then be used to purchase limited control over OIR™ queue order.
gollark: It would be environmentally friendly due to novel proof of gollariosity algorithms.
gollark: I was considering GTech™ GCryptocurrency™, for purposes.
gollark: You could do something where it gets distributed to low-balance accounts/addresses/whatever, but the issue with this is that that do not remotely correspond to people and can't be made to.
