Resuming- we find that Diphyabyla Hubrechti resembles Abyla Letukarii in four points: 

 i" by the shape of the somatocyst, 

 2" by the shape of the hydroecium, 



3" by the course of the canal which goes to the nectosac, 

 4" by the general appearance of the basal part of the nectophore. 



It resembles Diphyopsmae : 

 i" by the upper part of the nectophore, as concerns the ridges, 

 2" b)' the shape of the nectosac. 



Finally the shape of the immature bract is P /iysophoridA\k&. 



Subfam. Diphy opsin ae Hkl. SSa and 88 <5. 



Some of the following different species of Diphyopsinae bear two names: Diphyes and 

 Diphyopsis because by the effects of the conservation the stem had in many cases contracted 

 itself and lost many of its appendages. It was then in most cases impossible to make out whether 

 there were any special nectophores in the groups of appendages ("Specialschwimmglocken"), the 

 characteristic peculiarity which distinguishes Haeckel's genus Diphyopsis. 



So we begin be describing the species which decidedly do not show any sign of this 

 development; they are Diphyes contorta nov. spec, Diphyes dispar Cham. Eys., Diphyes Nier- 

 straszi nov. spec, Diphyes indica nov. spec. 



Then we describe three species which resemble Diphyes, but of which we could not 

 definitely say whether there are special nectophores. Finally we describe four true Diphyopsis. 



Unfortunately all inferior nectophores (excepting Diphyopsis campanuliferd) were lost. 

 Of course there were many loose inferior nectophores of Diphyopsinae in the Siboo-a material 

 but only for two specimens, there was no question of determination. We suppose that the 

 inferior nectophores do not keep as well in the preserving fluid and are even more delicate 

 than the superior ones. This we have seen in some complete specimens, where the inferior 

 nectophore was quite crumpled up, the superior one tolerably well preserved (Cat. 50 C.B. (2) 

 Diphyes i^. Diphyopsis) Gegendauri nov. sp.).
