The relationships of the Cystonects are not at all certain. The gonophores of Rhizophysa arise in 

 a longitudinal meridian on the lower part of the air-sac, and are flanked on either side by a meridional 

 row of gastrozooid buds. Distally they all come to occupy a single meridional row. Each branchlet 

 of the gonophore has a subterminal medusa-bud in which, presumably, the eggs are developed. But 

 the early development of cystonects is quite unknown, except for Physalia. Hitherto they have been 

 placed with the Physonectae because in both groups there is an air-sac or pneumatocyst. But it seems 

 possible that the Physonectae have not passed through a Cystonect stage in their phylogeny, and that 

 the Calycophorae may be more closely related to the Physonectae than either group is to the 

 Cystonectae. The larva of Physalia would certainly seem to indicate a much earlier origin of
