98 REPRODUCTIVE ORGANS AND CLOACA 



ovary consists of a couple of folds united along 

 their ventral edges ; the space between the folds 

 is divided by partitions into about fifteen 

 pouches. 



ii. The oviducts are a pair of white, twisted tubes, 

 with thick gelatinous walls. They commence 

 with open mouths at the extreme front end of 

 the body cavity, close to the outer side of the 

 roots of the lungs ; and run back, increasing in 

 size, and becoming much convoluted. Their 

 hinder ends, the ovisacs, are greatly dilated, but 

 have thinner walls ; in these the eggs are stored 

 just before laying commences. Unlike the male, 

 the female has genital ducts distinct from the 

 ureters. 



2. The Cloaca. 



Dissect as in the male. 



i. The cloaca is very similar to that of the male, 

 except that the urinary and genital products are 

 discharged into it by separate ducts. 



ii. The bladder is like that of the male. 



iii. The oviducts open separately into the dorsal wall 

 of the cloaca, just opposite the bladder, by two 

 wide apertures separated by a narrow median 

 partition. 



iv. The ureters open by two small apertures, placed 

 close together, into the dorsal wall of the 

 just behind the oviducts.
