  • Description

    The shell is small, rudimentary, auriform (ear-shaped) and is situated far back on the animal. The shell is incapable of containing the body, and is reduced to the function of a shield for the lungs and heart. The shell is paucispiral, and is nacreous within. The columella is excavated into a pit for the reception of the shell-muscle.

    The animal has no rachidian teeth.

    Ecology

    Schizoglossa has eggs with a calcareous surface which lacks cuticle.
