* The true limits of this class were first indicated by Pallas in his * Mis- 

 cellanea Zoologica,' p. 74, Lugd. Bat. 1778. Lamarck conferred upon it the 

 name Annelides in 1812. 



t This fiimily should be referred to the class Entozoa. See Reports on 

 Zoology 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.
