Jelly -masses. 



In hauls from 1670 and 1770 fathoms M-ere lenticular 

 masses of jelly 20 and 13 millim. in diameter respectively, 

 "which seemed to ha^^e been parts of the umorella of some 

 Medusa Mhich had died, perhaps, in a higher stratum of 

 water. I have thought their occurrence worthy of notice, 

 because a problem to wliich future investigators should turn 

 their attention is that of the degree of permanence of the 

 jelly, which forms the bulk of many pelagic organisms, 

 after death and in the middle depths of the ocean. It would 

 be interesting, for example, to leai-n the extent to which 

 such jelly-masses are the food of organisms living in the 

 greater ocean depths. 



SIPHOXOPHORA. 



C A L Y C O P n O R ^. 



Monophyidas. 

 Sjjhceronectes gracilis, Hseckel. 



Specimens of about 8 millim. in diameter were taken in 

 hauls from depths of 510, 810, 1510, 1670, and 1770 fathoms. 



Dorajnasia picta, Chun. 



To this species belong three individuals in a haul from. 

 1570 fathoms and three taken in the three hauls from 1170, 

 1190, and 1300 fathoms. 



Diphyidae. 



Diphyes bipartita, Costa. 

 Eudoxia campanula, Leuckart. 



A number of Eudoxia were present in hauls from below 

 810 fathoms and down to 1610 fathoms. 



It seems that they are to be identified with the Eudoxia 

 campanula, Leuck., which was caught in such large numbers 

 in the North Atlantic during the Plankton Expedition. It 

 has already been shown that this species is often present in 

 large numbers in the deeper waters of the Mediterranean 

 and in the North Atlantic. Their relative abundance is 

 indicated by the following catches made by the ' Oceana^ : — 



Between 810 fathoms and the surface, 6 individuals.
