Description

The shell grows to a length of 10 mm.

The stout shell has a white tip. The whorls are whitish and the summits of the five ribs are brownish. The ribs are continuous from base to summit and the cross-section of the shell forms an exact pentagon with rounded angles. The ribs are not continuous, except accidentally. The other characters are closely similar to Fenimorea pagodula (Dall, 1889)[3]

Distribution

This marine species occurs from North Carolina (Cape Hatteras) to Florida, and in the Gulf of Mexico off Western Florida and in the Caribbean Sea off Aruba and French Guiana.

gollark: Not only are they steganographically embedding identifying data in documents you print, or running out of ink or printing wrong at inconvenient times or requiring DRMed ink cartridges, but the drivers are moderately bad.
gollark: I have always said printers couldn't be trusted.
gollark: Why not just use `os.listdir` or whatever?
