Resumo1. A short description is given of hair-peg organs which are present in large numbers of the anterior part of the body and appendages in Humarus. 2. Observations have shown that these sense organs respond to a water current by deflexion about a hinge at their base. 3. Electrophysiological studies reveal that impulses are generated by the sense organs when they are deflected by a water current. 4. Action potentials occur at a water flow of about 0·30 cm/sec and above. 5. It is suggested that this represents a "distant touch" mechanism.
