ones. These consist of a siphon, a group of tentilla and some small buds, probably the bract 

 and the g-onophore. 



On PI. VI, fig. 52 we gave a sketch of one of these developed groups; it shows clearly 

 the siphon, the bract, the tentilla and one bud, the future gonophore. There is no trace to be 

 seen of the development of a special gonocalyx in the group. 



So instead of using the genusname Diphyopsis, we go back again to the original name 

 Diphyes as it was given by Chamisso and Eysenhardt, being convinced that the Siboga-specimens 

 are identical to theirs.

The length of these 50 specimens varied from 7 to 1 5 mm. They differ essentially from 

 Dipliyopsis campamilifera O. et G. which is described on p. 49 through the absence of any 

 special nectophore in the groups of appendages and also through the difference in size. There 

 were only superior nectophores, though some verv much developed inferior ones were to be 

 found on the stem of a few specimens. Another ditference with Diphyopsis campantilifera is 

 the length of the stem between two groups of appendages. In Diphyes Nierstraszii there is a 

 considerable distance between two groups. This occurs in all the specimens whose groups are 

 sufficiently well-developed. It is not merely in some of them that we noticed this particularitj'. 

 At the same time we found only four developed groups on one specimen ; in Diphyopsis cam- 

 panulifera of the Siboga expedition we have found a much larger number (see PI. VIII, fig. 63). 

 These groups are also much larger in size than the same in Diphyopsis campajiulifera at the 

 same stage of development. The shape of the nectojahores, of the nectosac, the somatocyst, 

 the hydroecium etc. is the same as in Diphyopsis.
