1. the image of the plate is missing entirely
2. the numbering is off - 21 on the plate (the big fancy centrepiece) is listed in the 20th <li>

The 10th <li> has two entries conflated

• Bend Traverse, Counter-Pointed. P. 18, f.9.
• Bend Escartele, Grady, Or Embattled Grady. P. 18, f. 10.

What should be the 40th <li> is actually split into two list items ..

• Bendy sinister-paly. For Bendy
• Paly see P. 2. f. 32.

.. should be

• Bendy sinister-paly. For Bendy Paly see P. 2. f. 32.
