There is a receptaculum seminis which receives the oviducts and 
connects with a dorsal uterus. There are paired shell glands empty¬ 
ing into the uterus. Ripe sperm was found in the receptaculum. 
The male organs are paired testes, vasa deferentia, and a mass of 
seminal vesicles in the midline. These vesicles contained no ripe 
sperm.
