The white pigment-dispersing and -concentrating Standard Integrated Responses (SIR) of eyestalkless prawns evoked by the fractions obtained by passing the ethanol-soluble material of the supraesophageal ganglia with the circumesophageal connectives attached through the column of Sephadex LH-20. Fingerman and Rao (1969), as stated above, found that the eyestalks of this prawn contain substances that disperse and concentrate the white pigment of the fiddler crab, Uca pugilator. These investigators chromatographed the ethanol- soluble material from eyestalks of Palaemonetes on a column of Sephadex LH-20 having the same dimensions and under the same conditions as employed in the present investigation, and also collected 2 ml fractions as above. The substance that dispersed the white pigment of the fiddler crab peaked in fraction 15 whereas the substance that concentrated the white pigment of this crab peaked in fraction 20, the same two fractions of the eyestalks that had the maximal corresponding effects on the white pigment of Palaemonetes (Fig. 3). It would seem most simply then that the corresponding effects produced by the fractionated extracts of eyestalks from Palaemonetes in the prawn and crab were due to the same sub- stances. Fingerman and Rao (1969) had, however, found that although dispersion.
