Family LOVENELLIDAE 

 Eucheilota sp. 

 (PI. V, fig. I) 

 Occurrence: St. 91. 8. ix. 26. False Bay, South Africa. Net: TYF 0-5 m. i specimen. 



I am not inclined to establish a new species for this single specimen, though it does not agree with 

 any of the 14 species of Eucheilota described up to now. While on the Danish 'Galathea' Expedition, 

 in the Indian Ocean and western Pacific I saw many medusae belonging to this genus, apparently 

 representing several diflferent species, some of which could not be referred to any known species. 

 A thorough revision is needed before a reliable limitation of these numerous forms can be carried 

 through. Provisionally, therefore, I shall only give a short description and a figure of the little medusa 

 taken in False Bay by R.R.S. 'Discovery'. 



The umbrella is almost hemispherical, 2 mm. wide and i mm. high, with very thin walls. Manu- 

 brium narrow, mouth with an indication of four simple lips. Gonads (male) egg-shaped, about one- 

 third as long as the radial canals, situated a little outside the middle of the canals ; one of the gonads 

 is undeveloped. Radial canals and ring-canal very narrow. Velum narrow. There are two well- 

 developed perradial tentacles with broadly conical basal bulbs, and two globular perradial bulbs 

 without tentacles; moreover, four small interradial bulbs and a few very tiny marginal swellings. 

 Eight fairly large adradial marginal vesicles. In each octant about five marginal cirri, typically spiral 

 with a solid endoderm and a terminal knob containing nematocysts. There is no black pigmentation 

 anywhere, neither on the stomach nor on the marginal bulbs.
