The nectosac is cylindrical, narrows out very yj^radually. it has the shape of a true Diphyes. 

 It is accompanied by the tubular, elongated somatocyst which is nearly of the same breadth 

 from top to base. The hydroecium-top is situated a little above the last third part of the whole 

 length of the nectophore. 



In two specimens we could clearly see the young bud of the inferior nectophore, but 

 nothing can be said of the clusters of appendages, which are badly preserved and incomplete. 

 We could not find out whether there are special nectophores in the groups.

The four superior nectophores are very slender, tiny and delicate. Their length varies 

 from 6^0 — 8^2 mm. At first sight they resemble very much the upper nectophores of Doramasia 

 bojani Ch. or our Doramasia pictoides. But also here the division occurs of one of the four 

 principal ridges into two (PI. VIII, fig. 58) near the ape.\ of the nectophore. In this respect 

 they resemble Diphyes Steetistrupii Ggbr. and Diphyes ( Lihyopsis) malayana. They have also 

 lateral teeth possessing the same shape a.?, \n Diphyes Steenstrupii Gghr. The points of re.semblance 

 with the latter are numerous ; the ventral ridges of the hydroecium only having a more inclined, 

 concave course. All the ridges are serrated ; the dorsal tooth differs one third in length from 

 the lateral ones. 



The nectosac narrows very gradually towards the top of the nectophore. The somatocyst 

 is narrow, nearly of the same breadth and runs along the lateral sides of the nectosac. 



The hydroecium has the same position as in Diphyes (Diphyopsis) malayana. 



As is shown above there is a great resemblance with Doramasia pictoides, but we have 

 distinctly seen a bud, the future inferior nectophore in one of our specimens and we even 

 possess a complete specimen (Cat. 50 C.B. (2)). Unfortunately the inferior nectophore is absolutely 

 unrecognizable; it has quite shrivelled up through the preservation. 



Another specimen (Cat. 80S. (2)) shows a distinct group of appendages; the bract is 

 developed but no traces are to be found of any gonophores or special gonocalyces. .So we cannot 

 make any conclusion about these four nectophores belonging to the genus Diphyes or Diphyopsis.
