a genus of birds, belonging to the order of anseres. See Ornithology Index. Clus- ius makes the procellaria pelagica or stormy petrel the Camilla of the sea.

Vel mare per medium fluctu suspensa tumenti. Ferret iter, celere nec tingeret aquore plantas. VIRG.

She swept the seas; and, as she skimm'd along Her flying feet unbathe'd on billows hung. DRYDEN.

These birds are the cypricilli of Pliny, which he places among the opodes of Aristotle; not because they want- ed feet, but were nuxeres, or had bad or useless ones; an attribute he gives to these species, on a supposition that they were almost always on the wing.
