Onycha

American Tract Society Bible Dictionary

An ingredient of the sacred incense, whose fragrance perfumed the sanctuary alone, Exodus 30:34 . It is conjectured to mean the Blatta Bryzantina of the shops; an article which consists of the cover or lid of a species of muscle, and when burnt emits a musky odor. The best onycha is found in the Red Sea, and is white and large.
