Half-filled circles are the controls. Open symbols are eyestalks, closed sym- bols nervous tissue. Circles, tissue of Cambarellus; triangles, tissue of Orconectes. The results are presented in Figure 2 where each point represents the average of 10 crayfish. As evident from the figure, each extract contained RPCH and RPDH. The eyestalks of dwarf crayfish and Orconectes contained more RPDH and less RPCH than the supraesophageal ganglia plus the circumesophageal connectives. Significantly, the eyestalks and supraesophageal ganglia plus the circumesophageal connectives of Orconectes contained sufficient RPDH to produce an appreciable response in dwarf crayfish but no red pigment dispersion occurred when extracts of these tissues were injected into specimens of Orconectes (Fingerman, 1958). Responses of Orconectes to chromatophorotropins of dwarf crayfish and Orconectes Since direct injection of extracts of eyestalks and supraesophageal ganglia plus the circumesophageal connectives of Orconectes into dwarf crayfish did produce red.
