^Johannes Gistel, Naturgeschlchte des Thlerreichs, 1848, makes a new genus Vndina 

 for Linkia Nardo. Undina is preoccupied In fishes. He also makes a new genus 

 Catantes for " Linckia Agasslz." In other words, he coins two new names for the same 

 generic group. There was no necessity for these new names.
