Resumo

1. A brief description is given of the food collecting net of the echiuroid worm Urechis caupo. Water flows freely through this mucous net. 2. By introducing into this mucous tube proteins of known molecular size, namely, ovalbumin, 44,000; human serum globulin, 176,000; and hemocyanin (Palinurus), 450,000, the size of the openings was found to be approximately 40 Ångströms. 3. Experimental uses for the mucous net are given, and other possible uses suggested.
