Scutibranchia']^ in which he comprises the families Helicinacea^ Proser- 
pinacea^ Hydroccenacea^ Neritacea^ Trochoidea, Btomatellacea^ Haliotidoe^ 
and Fissurellacea, the first two being terrestrial and pulmonate, the 
Hydroccenacea and a part of the Neritacea living in freshwater [Hydro- 
ccena rather terrestrial], the rest marine ; the gills, when they exist, are 
rather pinnate (feather-shaped) than pectinate (comb-shaped). Gebiss
