VIII. — Abstract of some Investigations into the Structure of the 

 Oligocholia. By Frank E. Beddard, M.A., &c. 



Oligochasta intermediate between the Limicolge and Terricola3 

 of Clapardde. 



Claparede's division of the Oligochaita into 01igocha3ta 

 Limicola3 and Oligochaita Terricolaj (" Recherches Anato- 

 nriques sur les Oligochetes," Mem. Soc. Phys. Geneve, t. xvi., 

 1862), though certainly expressing the knowledge of his 

 time when Lumbricus was the only terrestrial Annelid whose 

 anatomy was known, has been shown to be no longer tenable. 

 Many of the characters believed to be restricted to the 

 Limicolas have been discovered in Earthworms. The only
