Abstract：
:A novel type of pore canal is described from the cuticle of three species of Gammarus. Each canal passes from the epidermis vertically through the endocuticle and exocuticle, and in the most distal layers of the latter is slightly expanded. Before entering the epicuticle the canal narrows, forming a neck the base of which is encircled by an electron-dense collar. Several tubular structures arise from the collar and pass distally into the reticular innermost regions of the epicuticle. Within the neck and just below its opening at the cuticle surface, a rod-like structure is inserted; this protrudes a short distance from the pore. Each pore canal is connected to many necks; the openings of the latter are aligned in rows over the surface, the openings and rows being about 0.15 and 1.0 micron apart, respectively. Changes in the pore and canal contents are visible and their significance is discussed.
