In the course of a recent study of the parasites of the Unionidae, the following data in regard to the time of sexual maturity in certain species, and their method of carrying their glochidia, were obtained. This primary inquiry involved the microscopical examination of the sexual glands of each individual. And in females whose gills were found swollen with the sexual product, the portion of these organs forming the marsupium and the stage of development of its contents, were also noted.
