* 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. 
+ This family 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.
