THE carnivorous Annelids are mostly sexually 

 separate. The same was originally the case with 

 the Apodidae, which arc now, however, mostly 

 hermaphrodite (see Appendix V.). Males, generally 

 smaller than the females, have been found at intervals 

 in the best known species, and these seem to suffice 

 for occasional cross fertilisation. 



The sexual elements of the Annelids frequently 

 develop out of the ccelom epithelium (see Fig. 11, p. 

 54), and then, falling off, ripen in the body fluid. 

 They are discharged through the nephridia, which 

 may or may not be specially modified into sexual 

 ducts. 



In the section on the excretory glands, we have 

 already briefly described the sexual glands in the 

 Apodidae. We have here, then, only to describe the 

 process of formation of the sexual products some-

 of clearness what was said above. The genital glands
