Description
The length of the shell attains 14 mm. The shell is subfusiform and is longitudinally ribbed. The eight ribs are distant. The shell shows very minute, close revolving lines, which become gradually more distinct on the body whorl. The siphonal canal is very short. The simple and entire outer lip is obsoletely, widely notched and curved outwards. The lip is reflexed and slightly callous near the upper extremity. The columella is straight.[2]
Distribution
This extinct species was found in Miocene strata off Yorktown, Virginia, USA.
gollark: Yes, the interweb™ appears to agree with that etymology.
gollark: Yes, the mandatory scene where they analogise it using a piece of paper or something.
gollark: For 4D *Euclidean* space the 2D/3D stuff mostly just generalizes fine, as far as I know.
gollark: There are theories of how they might work, but any useful ones involve ridiculously complex maths and not vague ideas of extra dimensions.
gollark: Also, I don't think that "the universe is the 3-dimensional surface of a 4-sphere" thing is actually... true?
