Drawings of the shell of Norelona pyrenaica

Norelona pyrenaica is the type species of the genus Norelona.

Shell description

The shell is narrowly umbilicated, flattened above, thin, pellucid, olivaceous corneous. The shell has 4½[2] whorls, that are rather flattened. The last whorl is not descending. The peristome is acute, reflected, white-lipped.[3]

The width of the shell is 17–21 mm. The height of the shell is 9–11 mm.[2]

Anatomy

This species of snail makes and uses love darts.[4] (Image of reproductive system.)

Distribution

This species is endemic to the eastern Pyrenees, France.[5] (map of distribution, map 2)

It is also known from Spain since 2007.[6]

gollark: But what if you need to give someone 92 guns?

gollark: To be truly marxist, you should have communism where literally everyone is given 100 guns by the state.

gollark: Didn't Marx say something about not taking away guns from the proletariat?

gollark: They seem to have decided that now knives are EXTREME DANGER™ and are overregulating them, despite them being waaaay more useful as general-use tools than guns.

gollark: I mean, knives would be very UK.
