1. Body colour changes of the crucian carp during spinal thermal stimulation were recorded photoelectrically. 2. Warming the spinal cord induced darkening, whereas cooling induced lightening of body colour. 3. After transection of the medulla oblongata posterior to the vagal lobe, the same colour responses as in intact fish were induced, apart from one of the seven responses to spinal cooling. 4. After spinal pithing, thermal stimulation of the spinal cord failed to induce the responses. 5. The present responses are considered to indicate influence of spinal thermal stimulation on the cutaneous sympathetic systems of this fish.
