A Lion Coward

No, not the Cowardly Lion.

In heraldry, a lion (or presumably other some other beast, although all of the examples I found in a cursory search were leonine) coward is a representation of the animal with, as one might expect, its tail tucked down in between its legs, instead of curled up behind.  Here's an example of a lion rampant coward (LJ users, you'll probably have to look at the original sidebernie.blogspot.com version).

On the bright side, this seems to be a purely descriptive term, and (again, following only a cursory search) does not actually seem to suggest anything about the name associated with the heraldic symbology.  That's just what that particular form of lion is called, to distinguish it from (for example) a lion rampant, or a lion rampant regardant, or a lion passant crowned, or a lion passant guardant, ducally gorged, or a lion sejant guardant erect, or a lion rampant queue-fourché, or a tricorporate lion, etc. etc.  And that's just lions.  For some light reading, I recommend http://www.archive.org/stream/completeguidetoh00foxdrich#page/n5/mode/2up.  Very interesting for the flipping through of.
