Gules, a sword point upwards in pale Argent, hilted and pommelled Or, between three fetterlocks of the Last, a canton voided of the Second.

Above the Shield is placed an Helm befitting his degree, with a Mantling Gules powdered of fetterlocks Or, doubled Or, and on a Wreath of the Liveries is set for a Crest a dun Argent masoned Gules, window and port Sable, issuing therefrom a bearded demi-man clad in mail Proper with surcoat as the Shield blowing a bull's horn Sable, and in an Escrol over the same this Motto " Defend and Shelter "
