Diphxopsis campamilifcra O. et G. 



This very well-known species Diphyopsis campanulifera O. et G. is found in rather large 

 quantities in the Siboga material. They are by far the best preserved. They owe this to their 

 great consistency, the gelatinous substance being well-developed and firm. 



We found four complete specimens one of which we sketched (PI. VIII, fig. 63) 42 loose 

 superior nectophores and 9 loose inferior ones. These latter however are not well-preserved 

 enough to make us feel sure that they indeed belong to Diphyopsis campanulifera O. et G. 



The foiu- complete ones are at the same time the largest in size, of Cat. 32 .A. the length 

 of the two nectophores is 33 mm. of Cat. 80 A. 28 mm. and 20 mm., sizes which we only 

 found back in DipJiyabyla. 



The sketch given is of Cat. So A. size 28 mm. The stem and appendages are well- 

 preserved in this specimen. The difference in size of the groups of appendages with relation to 

 the size of the superior nectophore should be particularly noticed and the same in Diphyes 

 Nierstraszii which perhaps is closely related to Diphyopsis campanulifera. 



The enc/o.vid of the latter, Ersaea Lessoni Hu.xl. we found in the unusual great number 

 of 714 specimens, the largest quantity of one species of Calycophorac of the Siboga e.xpedition. 



These .specimens vary in size but do not show any structural difference with the Ersaea 

 Lessoni as it was once described very clear!)- by Huxley 59, Fewkes 81 etc. 



For completeness" sake we give a sketch of one of the more perfect .specimens.
