Tlie ovary is brownish below, yellowish above. The epididymis and testicle are salmon-colored. The ovi- duct is white, the prostate salmon. The genital bladder is small, oval, with an extremely long duct, which has a flagellate branch. The duct enters at the lower end of the vagina. The penis sac is narrow, cylindrical, ex- tremely long, with a flagellate extension. The retrac- . tor muscle is inserted beyond the middle of the length of the penis sac, the vas deferens at the commencement of the flagellum. There is a stout, long, cylindrical vaginal prostate, whose apex is extended into a flagellum, which shortly becomes bifurcate, there being a bnlblike expansion on each branch just beyond the bifurcation. In some individuals the bulb-like expansions are still larger and stouter than in the figure. The cylin- drical extension of the vaginal ijrostate is abruptly truncated, the two flagella entering near the end, not at the extreme terminus. Var. Diabloensis, J. G. Cooper.
