𩑶尾（又作胡𦙶二形同戶孤反謂牛頜垂也詩云狼跋其胡是也論文作壺說文圓器也壺非此用）。

Dewlap and tail (𩑶尾): Also written in the two forms 胡 and 𦙶. Fanqie: 戶孤 [hú]. It refers to the hanging flesh under an ox's chin. The Shijing says: 'The wolf steps on his dewlap (胡)'—this is it. The treatise writes it as 壺. Shuowen jiezi: 'A round vessel.' 壺 is not used in this sense here.
