From the hinder filaments of the nucleus of the sexual organs only the 
vasa deferentia or oviduct arise ; the other parts being all developed from 
the cuticular epithelium. The external passages originate as double nuclei; 
all the unpaired parts originate from adjacent paired parts, and are thus 
to be regarded as secondary or more complex forms. The male and female 
external passages are perfectly homologous organs. The tissues of the 
oviduct, uterus, and vagina in $ , and those of the vasa deferentia, the 
accessory organs, and the ductus ejaculatorius in $ arise quite indepen- 
dently of each other, and have only a secondary connection.
