The shell attains a size between 17 mm and 60 mm. The solid, imperforate shell has a conic shape. Its color pattern is olivaceous brown, maculated obscurely above with brown, green or white. The seven whorls are longitudinally costate below the sutures and above the periphery, with two spiral series of tubercles around the middle of the flattened upper surface, or sometimes finely irregularly plicate over the whole upper surface. The periphery is acutely carinated, bearing numerous short compressed triangular radiating spines. The flat base of the shell is densely radiateiy lamellose-striate, with a strong rib revolving midway between the periphery and the center The aperture is oblique, pearly white within, transversely ovate, deeply channelled at the periphery. The columellar region is white, strongly bicostate, deeply excavated at the position of the umbilicus. The parietal callus is not much extended.

The operculum is oblong with a submarginal nucleus. The outer surface is white, with a strong curved central rib, its terminations joined by a A-shaped ridge.[3]

gollark: Anyway, your idea of making longer messages work *was* somewhat good, so I did that.
gollark: This is not in fact always the case.
gollark: Also, it assumes there will always be a reference which always has a cached message.
gollark: Correction: it *does* populate replyee in the Discord-side code but I think your IRC-side code is not updated to acknowledge it.
gollark: Additionally, your longer message fix would run into some accursedness I encountered with encodings.
