A variety of ciliates representing most of the major cliate groups were found to adhere to the ends of the tentacles of Podophrya collini . Reduction of ion concentration in the medium, low temperature, and treatment of the food ciliates or the suctorians with agents presumably interfering with choline‐acetylcholine balances in the suctorian or ciliate depressed the capture efficiency. Addition of sulfhydryl containing com pounds to the feeding situation and treatments which reduced the swimming vigor of the ciliates gave enhanced capture efficiency. Although killed but unlysed ciliates would not adhere to the tentacle ends, agar particles containing ciliate breis or a mixture of salts plus experimentally determined organic compounds would adhere.
