概要	In the spermathecal duct of the female cricket Gryllus bimaculatus, the glandular cells, each of which has a central cavity, and the cuticular ductules, extending from the cuticular intima of the spermathecal duct, are widely distributed along the duct's length, except in the proximal and distal regions. The cuticular ductules approach the glandular cavities along a tortuous course and enter them, or run down towards them to terminate in the region of the basement membrane. When an isolated spermathecal duct was incubated in an ionic lanthanum solution, deposits of lanthanum were found in the lumina of the cuticular ductules, the secretory cavities of the glandular cells, and in the openings of the cuticular ductules to the lumen of the spermathecal duct, but also in the intercellular space, and the surface of muscle fibers surrounding the spermathecal duct. This finding suggests that each cuticular ductule is a tripartite passage between the haemocoel, the glandular cavity, and the lumen of the spermathecal duct.
