Remarks. Asano (1938b) assigned this species to Nautilus scapha Fichtel and Moll , and his identification was followed in subsequent Japanese works. Nonion scaphum is a senior synonym of Nonionina communis d’Orbigny (1846) as demonstrated by Rögl and Hansen (1984). It is distinguished from N. labradorica in a lesser growth rate and more compressed test.
Occurrence. Sporadic in the Minebari Formation.
