A new corer is described which may be used in sediments of shallow standing waters, such as in rice fields, and which facilitatesthe study of the vertical distribution of the invertebrate fauna at 2 cm depth intervals. Its small surface area permits quantitativesampling of the sediment-dwelling fauna, particularly the chironomid larvae, around the roots of rice-plants. Results arepresented and the efficiency of the sampling method is discussed.

A modified version of the light weight "Murray" piston corer is described. This corer may be used in any depth of water and is particularly suited to loose unconsolidated sediment. The new design overcomes some of the problems inherent in the earlier model.
