Figures, photographs and measurements 

 Specimens were examined, figured and photographed with an Ol-

 specimens. All absolute measurements of nematodes are given um. 



Sediment horizon 



This can be taken as 0- 1 cm unless a statement is made to the contary 



in the descriptions.

SPECIES LIST 



The systematic classification of the order Tylenchida is based on that 

 of Fortuner, Geraert, Luc, Maggenti and Raski (1987-1988) 'A 

 reappraisal of Tylenchina (Nemata)'. That of the order Rhabditida is 

 after Lorenzen (1981).
