Description

The size of an adult shell varies between 31 mm and 54 mm. The shell is elongated and the mineralized shell is made of calcium carbonate (Chalk). The whorls of the spire are more or less plicately ribbed, sometimes only the upper ones. The body whorl is smooth except at the base, where there are revolving grooves. The color of the shell is very light grayish yellow, or yellowish brown, or chestnut.

Some specimens are shouldered varieties and were described as Pusionella catelini (Petit de la Saussaye, 1851) [3]

Distribution

This species occurs in the Atlantic Ocean off West Africa and particularly Gabon.

gollark: I don't want tiny compact-machine-fitting things (well, I kind of do, but separate to giant, awe-inspiring ones incorporating fusion plasma injectors of death, hopefully), I want giant ones requiring huge amounts of infrastructure to support it, with cool visual effects, massive (actually fitting, you know, a *fusion* reactor) power output (ideally via steam turbines), that sort of thing.
gollark: Also, I hope the new fusion reactors take inspiration from ReactorCraft.
gollark: The mekanism ones are a bit crazy. If you want oxygen, feeding the separator RF from its own hydrogen run through a gas-burning generator, *it works fine*.
gollark: Even when I had about 8 upgraded ones.
gollark: The nuclearcraft ones are just too slow.
