108 REPBODUCTIVE ORGANS AND CLOACA. 



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, increa sing 

 in size, and becoming much convoluted. Their 

 hinder ends are greatly dilated, but have thinner 

 walls. 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 cloaca 

 just behind the oviducts.
