The ypotryll, or hippotryll, is an heraldic monster of awesome ugliness, with a camel’s humps, a boar’s face, and cloven hooves.  It was used as a badge by Tiptoft, Earl of Worcester c.1460 [Dennys 166].  The ypotryll does not seem to have a default posture; the illustration shows an ypotryll passant.

The Canton of Attilium bears as a badge:  An ypotryll passant Or.

Edelgard Erzsébet von Württemberg bears:  Purpure, an ypotryll dormant Or.

Nina of Bright Hills bears:  Or, a pale azure and overall an ypotryll rampant gules.
