natural history, a genus of siderochita or crusted ferruginous bodies, formed in large and in great part empty cases, including a small quantity of an aqueous fluid.

Of this genus there are only two species: 1. The thick-shelled enhydrus, with black, reddish-brown, and yellow crusts. 2. The thinner shelled kind, with yellowish-brown and purple crusts; neither of which ferments with aqua fortis, or gives fire with steel.
