Half gold and half black with a marlet (a heraldic bird) at the top and at the bottom a sword, a crown and a tree. A marlet is a martin or bird which has an exact heraldic significance, namely that the arms relates originally to and denotes a fourth son in a family. This along with the antique crown perpetuates the old legend that the first McCurdy was the fourth son of the King of Scotia (Ireland). Queen Tea Tephi is described in ancient writings as "a tender twig". She is represented on the royal Coat of Arms by the top branches of a fir tree.

There have been a number of other McCurdy Coats of Arms but most have been lost.
