On the upper surface of the mouth is an ivy wreath. Around the body, beneath a zone of tongues, are fourteen dancing komasts. The figures are dancing excitedly with legs and arms flailing. In the lower register are nine sirens and one water bird. The sirens all face left, the water bird faces right. Between the komasts and sirens is a band of crenellations with concentric squares in the interstices.
Many of the figures' details are incised. Some red added.
