DISCOVERY REPORTS 



This species has separate sexes. The gonads are numerous, arranged in a series along 

 both the adradial and the interradial side of the genital slits ; the eggs are small and very 

 numerous. It may thus be concluded with a fair degree of certainty that the species is 

 not viviparous, but probably has a typical Ophiopluteus larva. 



The occurrence off the South Sandwich Islands of this species, which was hitherto 

 known only from the Kerguelen region, shows that it must be widely distributed in the 



Antarctic seas.
