Lamarck conferred upon it the name Annelides in 1812. t This family should be referred to the class Eutozoa. See Reports on Zoologjf and Botany, translated for the Ray Society, p. 292. A worm, presumed to be identical with the Mermis nigrescens of Dujardin, has been found in great abundance at Fairford in Gloucestershire. An ac-count of it will be soon published, we have reason to believe, by the Rev. L. Jenyns. Ann. ^ Mag. N. Hist. Vol. xvi. Suppl. 2 1
