the following arrangement of the shells hitherto generally united

1. Bulimus J type (jaw pectinated), with subgenera Boy'us, 
Bulimulus, Limicolaria, Achatinaj and Cochlicellus. Must be 
placed near Helix. 
2. Bulimm of the group of Pupa^^ (jaw finely striate), con^ 
fined to the Old World, and mostly European spp., to form a 
separate genus Buliminus, and be placed with Pupa, Clausilia, 
Vertigo, Vhondrus, and Eucalodium, in the family Pupidae. 
3. Bulimm of the group of Orthalicus^’ (ribs of the jaw^
