these circumstances, it is difficult to 

 discriminate between these two buds, and it 

 will therefore be convenient when this is the 

 case, to suppress their individuality and to 

 refer to the whole body as the egg-capsule, or 

 simply, the capsule. Where, however, the 

 " select " polypite is recognizable, as in 

 ATHECATA,and is distinct from the reproductive 

 bud, the latter with its envelope is also called 

 the " gonophore." 



Process of Budding, and Budding 

 of Medusae. The process of budding, as 

 previously stated, is by inflations of the body 

 wall, which is composed of an inner and an 

 outer layer. This process takes place not 

 only in the polypites, but also in the Medusae, 

 in which latter case the buds are Medusae. 



Ovaries are situated in body wall, 

 also in radiating canals of Medusae. 

 Ova are formed between the outer and inner 

 layers of the alimentary cavity. This is the 

 case also in the Medusae, but with some of 

 these ova also occur in sacks (inflations of the 

 layers) in the canals which radiate from the 

 stomach cavity. The important distinction 

 between budding and ova-production should 

 therefore be clearly understood.
