HYDROMEDUSAE, SIPHONOPHORES, AND CTENOPHORES. 333 



In these specimens the stems and appendages are entirely lost, 

 and the nectophores themselves are so crumpled and torn that the 

 most that can be said about them is that they are certainly prayids. 

 And since the hydroecium (when distinguishable) reaches from one 

 end of the nectophore to the other, they probably belong to P. 

 cymbiformis.

The inferior nectophore of this species was discovered very re- 

 cently, and is so far known only from small examples (Bigelow, 

 19116). Unfortunately the present specimen is so crumpled that I 

 can add nothing to my previous account.
