None cataloged

The shell of Bostrychoceras begins as a tightly wound helical spire, like that of Nostoceras, from which hangs a U- or J-shaped body chamber, at least in the adult. The shell is covered with dense, strong, but unflared, ribs that are commonly sinuous and oblique. May nor may not have strong constrictions.
