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.
From Inquiries into the Origin and Process of the Science of Heraldry in England by James Dallaway, p445

An ample field of heraldic invention was now [during the reign of Richard II] expanded; for the escocheon, no longer singly charged with the hereditary bearing, admitted those of the wife by dimidiation or impalement, and of heirs general by quartering.
