A: Phoenix with nimbus and rays around the head, to left, standing on a crocodile, to right. Above, a scarab with outstretched wings. On the two sides, pairs of animals: swallows facing inwards, scorpions crawling to top and snakes with 'hands' raised in protection. (For an interpretation, cf. CBd-2.) In the free field to the left and right of the swallows, short notches.
B: Inscription in four lines: στο|μα|χο|υ → στομάχου. 'For the stomach!'
