that time several analCTous cases have been made kno^/m. 

 The scyphistoma larvae of Cassiopea , for example, were 

 found producing buds in larr;e numbers by Bigelow (1900), who 

 gives a detailed account of the method of budding in his 

 monograph on this Rhizostome, It may be further stated in 

 general, that the non-sexual process of production of buds 

 by the larvae is an important method of multiplication 

 among the Discomedusae, The buds usually develop, after de- 

 tachment from the parent polyp, into a second genei^ation of 

 scyphistomas , identical in form and fate with the original 

 ones. Buds may arise on the body of the scyphistoma, or 

 upon stolons from its base, and either singly or several 

 at a time. In Cotylorhiza the buds develop so rapidly and 

 remain attached so long that large clusters accumulate 

 about the base of the scyphistoma. According to some au- 

 thors, Goette, for example, the distal end of the bud in 

 Aurelia and Cyanea is destined to become the oral end of 

 the detached larva, developong mouth and tentacles. Fried- 

 ma nn , on the other hand, says ("Postembryonal dev, of Aure- 

 lia aur i t a " 1902) that in Aurelia he has found the opposite 

 condition, the mouth being invariably developed at the at- 

 tached end of the bud. This is the common relation in oth- 

 er forms.
