6. Soil Fauna of the Manured Plot. 



In the following lists the worms have been divided into two groups, 

 those belonging to the sub-order Terricolae of the order Oligochaeta, 

 which includes the true earthworms, Lumhricus, etc., forming one group 

 as Oligochaeta (Terricolae), and all other worms, probably principally 

 belonging to the family Enchytraeidae of the Oligochaeta, and to the 

 Nematoda, forming the second group as Oligochaeta (Limicolae), etc. 



The numbers following the names have the following meaning — the 

 first numbers give the months during which the species was met with. 

 The first numbers within the brackets give, above, the total number 

 found, and below, in Roman numerals, the levels in which they were 

 found. The second immbers within the brackets give, above, the greatest 

 number found at any one level, and below, in Roman numerals, the level 

 at which thev were found. Thus — Trichocera fuscata Mg. (larvae) 1-12 

 108 54n 



. indicates that larvae of Trichocera fuscata Mg. were found in 



each month from January to December; 108 were found altogether in 

 samples I, II, III and IV, i.e. between the surface and a depth of seven 

 inches, and that 54 of these were found in the second sample, between a 

 depth of one inch and three inches.
