of two ovaries situated in 

 the anterior end of the 

 body shortly behind the 

 eyes and two oviducts run- 

 ning more or less parallel 

 to each other and uniting 

 posteriorly of the common 

 genital opening, where they 

 form a common or single 

 oviduct. Both oviducts 

 receive throughout their 

 length a great number of 

 yolk glands. The second 

 organ which has a separate 

 opening into the genital 

 cloaca is the uterus with its 

 uterine canal. Both are 

 single; the uterus lies in 

 front of the penis pouch, ex- 

 tending to the region of the 

 mouth. The uterine canal 

 is dorsal to the penis pouch. 



The third organ with a 

 separate opening into the 

 genital cloaca is the mus- 

 cular bursa copulatrix which 

 functions as a female organ 

 of copulation. 



From the foregoing it is 

 clear that the genital cloaca 

 has five openings: (i) the 

 common genital opening
