Lumbricus (Linnaeus em. Eisen) 



36. L. rubellus Hoffm. Universally distributed in Britain. 



37. L. castaneus Sav. Similar distribution to last. 



38. L. festivus Sav. Less common than the foregoing. 



39. L. papillosus Friend (= L. friendi Cognetti). South of 



Ireland. 



40. L. terrestris Linn. Widely distributed. 



This list shows a total of forty species, with about a dozen 

 forms and varieties, some of which have been given specific rank 

 by one or other of our leading authorities. I have pleasure in 

 gratefully acknowledging a grant from the Government, through 

 the courtesy of the Royal Society, to enable me to carry out 

 this research into Annelid Bionomics and Economics.
