Blazon: Azure two hunting-horns palewise, mouths in chief and strings to the center argent, garnished and stringed or; in base a triple mount of the last
From The Blazon of Gentrie by Sir John Ferne (1586) p218
Blazon: Gules a lion passant guardant or
Ferne repeats the common trope that the arms of England originated from combining the arms of Normandy with those of Aquitaine after Richard I, heir of Eleanor of Aquitaine, took the throne. While this is difficult to prove, Richard I certainly used the three lions passant guardant during his lifetime, as evidenced by his Great Seal.
In use since at least 1563; registered 1908
Blazon: Gules three lions passant guardant or dimidiated with azure as many herrings in pale fesswise argent
Motto: Rex et nostra jura (The King and our rights)
The device of the lions dimidiated with herrings is obviously related to the famously peculiar arms of Cinqe Ports, though it is not clear whether this is an intentional homage or another case of dimidiation having an unexpected result.
