法蠃（盧和反案蠃者太常樂器也形如大蝸牛大如盃白如雪頂有孔孔通吹作美聲聞於數里說文水介蟲也從虫𣎆聲也經作螺俗字非也今言法蠃者以說法美音喻彼蠃聲也）。

Dharma conch (法蠃): Has the fanqie *lú* + *hé* (蠃). Note: The conch is a musical instrument of the Court of Imperial Sacrifices. It is shaped like a large snail, as big as a cup, white as snow, with a hole at the top through which one blows to produce a beautiful sound heard over several leagues. The *Shuowen [jiezi]* says: 'An aquatic shelled mollusk. Derived from 虫 with 𣎆 as phonetic.' The scripture writes 螺, which is a vulgar character and incorrect. Here, 'Dharma conch' uses the beautiful sound of preaching the Dharma as a metaphor for the sound of that conch.
