Shell description

The shells of species within this genus are very large and solid, with a tall spire, a rounded aperture, a broadly flanged outer lip, and a moderately long siphonal canal, which is flexed and inclined to the left. The varices are prominent and rounded, but are hollowed out on the inside.

Species within the genus Ranella include:

gollark: It worked quite well, though I did have to manually narrow them down a bit.
gollark: To get around all the work of refreshing for an hour, I made a userscript to refresh every few seconds and check if the time changes.
gollark: I did *almost* that.
gollark: Free, want ND or 2G prize.
