法蠃（魯和反爾雅云蚹蠃螔蝓也郭璞注云螔蝓蝸牛也案蠃色白太常樂器也吹作美音聲聞數里顏氏字樣正體作蠃從𣎆聲也經文多作螺俗字也此螺字有平上去三音又非今故不取也）。

Dharma conch (faluo 法蠃: [the lower word is pronounced with the fanqie] lu + he [luo]. The Erya says: 'The fuluo is the yiyu.' Guo Pu's commentary says: 'The yiyu is a snail.' We note: the conch is white in color and is a musical instrument of the Grand Court of Imperial Sacrifices (Taichang); blowing it produces a fine sound heard for several li. The standard form in the Yan shi ziyang is written 蠃, taking guo 𣎆 as phonetic. In sūtra texts it is often written 螺, which is a popular form. This character 螺 has the three tones of level, rising, and departing; furthermore, it is not ancient, hence it is not adopted.).
