 other into a testicle, so that the two sides of the genital ap- 

 paratus represented the two sexes. 



Sections of these genital glands show one to be a typical 

 cryptorchid testicle with tubuli seminiferi and the other a 

 primitive ovary with scattering Graafian follicles contain-

 oviducts, uterus, and vagina. From the Wolffian ducts have 

 formed typical vasa deferentia. The penis is normal in 

 form and extent.
