It became desirable after these preliminary experiments to observe the color reactions of blinded Ligia. For the isopod crustaceans, Tait (1910) reported darkening of Ligia occanica when the eyes were covered with an opaque mass, and Pieron (1914) obtained similar re- sults with blinded Idotca. In the decapods, however, differing types of responses have been found, depending upon the method of blinding em-.
