356 Binney’s Monograph of the Helices 
In 1822, the name of H. denotita was applied to it 
by Férussac. The editors of the new edition of La- 
marck's Animaur ‘sans Vertébres, have chosen to 
retain the latter name ; but, inasmuch as it is incon- 
sistent with the rules of priority adopted by natural- 
ists, and unjust to Mr. Say, it ought not to obtain. `
