(iron cells and copper cells) described in the inidgnt gland of the crayfish, Procambarus clarkil by Ogura (1959) and also Miyawaki, Matsuzaki and Sasaki (1961) are observed. The iron cells of Paratelphusa have a nucleus roughly 7 /*, in diameter and a large nucleolus; the cytoplasm is rather homogeneous and strongly basophilic. Copper cells have smaller nuclei (about 4 ^ in diameter) and vacuolated cytoplasm, the vacuoles often being filled with stainable substances. The metal cells in Zone III serve as storage centers of both organic and inorganic (, calcium) reserves. During stage C4 the interior of the metal cells is literally filled with substances positive to SBB and PAS. With MBB and Millon's. on the other hand, the gen- eral stainability of the metal cells was very low even in stage C4. Distinct droplets strongly positive to MBB and Millon's were observed in small amounts in the interlobular spaces, but very rarely inside the metal cells. These droplets were positive also to SBB and PAS. The observations reported here indicate a low- level of stainable protein in the hepatopancreatic tissue. This was further sub- stantiated by the biochemical tests for proteins (Millon's, xanthoproteic and biuret reactions) on whole tissue Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
