A specimen of Lymnaea stagnalis with abnormal, antler-like tentacles from a laboratory-bred colony was subjected to some experiments on tentacle behaviour. The snail appeared to be normal in all respects. Tactile stimulation of the normal tentacles resulted in normal reactions. Stimulation of the outgrowth of the left tentacle, however, did not cause any reaction whatsoever. This leads to the conclusion that this abnormal part of the tentacle lacked appropriate innervation.
