The division of the constituents of one group does not mean any difference with Chun's 

 observations. But Chun seems not to have noticed the very distinct division into two, as he 

 speaks of the intermixture of loose palpons and gelatinous polypoids on the difterent side- 

 branches. He does not write about the appearance of the large siphon and of the gelatinous 

 polypoid on the main-stem. 



Two very interesting papers on the structure of gonodendra in Physalia have just 

 appeared. The first was published in 1906 by O. Steche; it seems that the small spherical 

 generative organs of the gonodendron, which up to this time have been considered as andro- 

 phores only, are in other cases also gynophores. A complete gonodendron is either male or 

 female. The origin and the function of the medusiform gonocaly.K remains a mystery. 



The last publication on SipJionopJiores is that of Richter (1907) who independently of 

 Steche published an extensive work on the same subject which differs from the latter only in 

 minor details.
