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.
本文描述了三种钩虾角质层中一种新型的孔道。每条孔道从表皮垂直穿过内角质层和外角质层，在外角质层最远端的几层中略有扩张。在进入上表皮之前，孔道变窄，形成一个颈部，其基部被一个电子致密的环所环绕。几个管状结构从环处产生，并向远端延伸至上表皮的网状最内层区域。在颈部及其在角质层表面开口的正下方，插入了一个杆状结构；这个结构从孔中伸出一小段距离。每个孔道与许多颈部相连；后者的开口在表面上排成行，开口和行之间的距离分别约为0.15微米和1.0微米。孔道和管内容物的变化是可见的，并对其意义进行了讨论。
