The ink of cephalopods (6 species) has been observed by the electron microscope and the results obained were as follows: 1) The ink consisted of a latge quantity of substantial element and a small quantity of slightly amorphous element, the former seeming to be a particulate component and the latter a slimy fraction. 2) The shape of the particles was generally spherical and their internal fine structure was not observable due to their high electron density. 3) The size of particles showed a large variety within a species and, furthermore, even in the individual organism. However, the distribution curves of the particle sizu in all species examined were very similar to each other. A close resemblance was found in the average diameters of the squid and octopus groups, the former being 130-150mμ and the later, 120-150mμ. 4) An electron diffraction pattern of the ink particles could not be obtained.
