 One specimen. 



Chun (92) has given a very clear and accurate description of a Mojiophyid (found by him 

 n ' 88 close to the Canary Islands) having the shape of a true Diphyid but differing from the 

 whole family of Diphyidac by the total absence of any second nectophore, and has called it 

 Doramasia picta. During several consecutive days he observed about forty live specimens. None 

 of these ever developed a second nectophore, nor was there the slightest indication of the 

 growth of a bud, which might have developed into one (92 page 95). 



As we only had preserved material it is ever so much more difficult to come to any 

 positive conclusion about the presence or absence of a nectophore-bud in our Doramasia pictoides. 



It is however very remarkable that among the thousand and more (all Diphyid-Vike) 

 superior nectophores collected by the Siboga expedition there is only one, and a very tiny one, 

 which shows so clearly the naked stem devoid of any other appendages but a terminal group 

 consisting of a siphon, a tentacle and a bud .sitting closely together (PL I, fig. i). This bud 

 cannot be a future second nectophore as it is situated too far from the implantation of stem 

 and somatocyst and much closer to the siphon. Moreover the siphon is probably quite mature 

 and the development of the bud could not but have followed very soon. 



As Chun calls the Dip/iyid-\iV.& Mottophyidae Doramasia, there is no reason why we 

 should not use the same generic name. The specific details differ however too much — always 

 taken as granted that our specimen is a true Monophyid — to allow us to use the name "-picta''. 

 We therefore wish to call our Doramasia "pictoides" thereby indicating the relation which exists 

 between these two probably closely allied Monophyids. But if later explorations bring to light
