A description is given of the formation of a simple type of chromatic organ or melaniridosome occurring during the healing of experimental wounds in two species of grunt (Bathystoma aurolineatum and Haemulon sciurus). Newly formed melanophores and iridocytes in the substance of the wound became attracted to each other, and group themselves into permanent masses known as chromatic organs or melan-iridosomes. Chromatic organs of this type were observed in later stages of wound healing (6-10 days) when epithelialization and formation of the new corium were well advanced.
