podia. Representatives of this group were 

 found in a number of soils by B, I and J. 



(e') Various other amoebae have been found in the 

 soil by different investigators, such as A. 

 radiosa (F, J, K) and A. albida (J), 

 (b) Testacea, rhizopods with shells (tests), into which the 



whole body can be withdrawn. 



(a') Arcellidae, shells chitinous, pseudopodia lobose 

 or simply branched. Arcclla vulgaris was found 

 in the soil by A, B, C, F, I, J and N. A. dis-

 and H. tincta by B, H. minuia by J. 



(b') Difflugidac, chitinous shells covered by foreign 

 bodies. Representatives of this group found 

 in the soil are Difflugia pyriformis (B, F, I, J),

 cola, H. picta, H. rosea and 11. sylvalica (B). 



(c') Euglyphidae, chitinous shells with plates made by 

 organism, including Euglypha tuberculata (J),

 nema enchelys (A, B, C, J), T. lineare and T. 

 complanatum (B and J), Corythion dubium 

 (B and J). 



(d') Gromiidae, membranous shells, pseudopodia- 

 reticulate, forming a network, including Lecy- 

 thium (Pamphagus) hyalinum (Syn. Chlamydo- 

 phrys stercorea) found by A, B, C, D, F, J, 

 K and L, L. mutabile by B and F, Pseudodifflugia
