In Figure 1A these hemocytes aggregate in great numbers near the epidermis and soft cuticle (cut) of a crab fixed in a buffered glutaraldehyde-salt fixative. Granulocytes and hyaline cells appear scattered within the eosinophilic serum which contains numerous granules (arrow). Certain granules exhibit basophilia; others exhibit acidophilia.

Besides hyaline cells and granulocytes, a third type of hemocyte (intermediate or transitional type) can be seen within the hemocoel. In Figure 2A a specimen fixed in formalin:acid:salt during late intermolt, the intermediate type (transitional cystocyte) hemocyte (i, arrow) approximates the size of the hyaline cell (h) and exhibits tiny unstained granules within a less extensive cytoplasm than the granulocytes (g). Az-Eo, pH X900. Figure 2B shows intermediate cells (arrows) releasing tiny proteinaceous granules which have azo-coupled with DAS. The hyaline cell (h) contains diphenols. The hemocytes appeared in a specimen fixed 10-15 hours postecdysis in buffered formalin-salt. X600. Figure 2C represents a diagrammatic interpretation of the intermediate cells rupturing and releasing their granules, thereby forming a cytoplasmic network which may function in clotting. 761.
