The Heraldic Ibex

is an imaginary beast resembling the heraldic antelope in appearance, with the exception of the horns projecting from his forehead, which are serrated like a saw. Perhaps it would not be erroneous to consider it identical with the heraldic antelope.

The real or natural ibex is a native of the Alps, the Pyrenees and the Grecian mountains, where they abound in defiance of the hunters. It resembles a goat, but the horns are much larger, bent backwards, and full of knots, one of which is added every year.
