Heraldic Beasts?

[Bugbear]

You might want to have your library scare up a copy of Cecil Wade's book, The Symbolisms of Heraldry, published in 1898.

Thanks, I will look for that book at the accessible libraries.

This book does have a dictionary, but it does not seem to give the symbolic meanings of the animals, just short descriptions.
The Project Gutenberg eBook of The Manual of Heraldry; Fifth Edition, by Anonymous (eBook #16273)

There's one or two others over there.
