See Corvus, Ornithology Index.

Sea RAVEN, or corvo marino of Kongo in Africa, in Ichthyology, is about five feet long; but the most singular circumstance appertaining to this creature is the stone found in its head, to which the natives ascribe some medicinal virtues, and the delicate taste of its hard roe, which is still much admired, when died in the sun, and becomes as hard as a stone.
