CONCLUDING REMARKS. 



In Cassiopea Xamachana, then, multiplication of individu- 

 als takes place largely by two kinds of non-sexual reproduction, 

 strobilization and budding. In regard to the last, several 

 interesting questions naturally su^^est themselves, such as, — 

 the origin of budding in the scyphomedusae, which of the known 

 methods is nearer the primitive one, whether this has any re- 

 lation to strobilization, and the like; but until much more ev- 

 idence has been collected th-an we at present possess it will 

 be impossible to give to them conclusive answers. It seems 



to me to be highly probable, however, that the mode of budding 



i 



jthat occurs in Cassiopea will will be found to be the most high- 



i 



ily specialized of tliose so far known. It seems to be an es- 



ipecial adaptation to overcome the unfavorable effect on the dis- 

 ;tribution of the species caused by the sedentary mode of life 

 of the adult, a mode of life unusual with meausae. Dwelling 

 as it does on the bottom ir. quiet lagoons and bays, its eggs 

 stand lit/tie chance of wide distribution art! the plsjiulse would 

 not probably swim very far from their mother before becoming 

 ifixed. The individual buds probably do not swim very far ei- 

 ther, but the last one of a series of generations of buds may
