ced larvae of the same species. 



This, of course, is a mere assimiption, but it gains in pro- 

 bability when we find that the development of these larvae cor- 

 responds in most particulars with what Glaus has found to take 

 place in the egg larvae of another Rhizostome, Cotylorhiza. 

 I Up to this time the process of budding in the Discomedusae 

 has received but little attention. In 1841 Sars described 

 the budding in scyphistoma larvae that were supposed to be ei- 

 ther Aurelia or Cyanea. The buds, accordirg to this account, 

 may groN directly out from the main part of the body of the 

 larva, or they may be produced on stolons extending outward 

 from the foot. In either case, several buds may apparently 

 be formed in various positions on the scyphistoma at one time. 

 The figures show the buds still attached to the parent and with 

 a well developed cro^vn of tentacles at the distal end. Agassiz 

 (1860) also found a similar process of budding to occur occa- 

 sionally in Aurelia. Goette (1887) has confirmed these ob- 

 servations and has also found that the larvae of Cotyloi-hiza 

 tuberculata produce buds. In this species the process, as 

 described by Goette, is peculiar. A bud is formed as an out- 

 growth from the body of the scyphistoma, and as this grows it 

 gradually approaches the shape of its parent, but its relative 

 position is just the reverse of what Sars found, for the dis-
