Sorry, no etymologies found.
The taxonomy in ZooBank seems to be a bit outdated: they still have Prosobranchia with Archaeo-/Meso-/Neogastropoda, all now considered para- or polyphyletic groups with the exception of the last.
* Whelks are classified in various families in the infraorder [[Neogastropoda]].
