שְׁחֵלֶת f. Exodus 30:34 according to Hebrew interpreters, unguis odoratus, prop. the covering or shell of a kind of muscle found in the lakes of India, where the nard grows; which, when burning, emits an odour resembling musk: this is now called blatta byzantina, Teufelsklaue. See Discorid., ii. 10; and the Arabian writers in Bochart (Hieroz. ii. p. 803, seq.). The root is שָׁחַל to peel off, compare שׁיחלא the pod of dates.
